Giving thanks to the Hurricane Hunters and QuikSCAT scientists

Everyone knows that flying into hurricanes is dangerous work. The NOAA Hurricane Hunter aircraft have flown a number of dangerous flights over the years, most recently in Hurricane Felix on September 2 this year. NOAA P-3 aircraft N42RF (affectionately called Kermit), penetrated a rapidly intensifying Hurricane Felix as it approached Category 5 intensity. The aircraft hit four G's of acceleration in both the up and down directions in Felix's eyewall. Regulations require a flight to be aborted at that level of turbulence, and Kermit returned to base. A detailed inspection of the aircraft the next day revealed no damage, and Kermit returned to service for the remainder of hurricane season.


Figure 1. A NOAA P-3 refuels in Cold Bay, Alaska (left) on its way to the Aleutian Islands to fly a mission in the 1987 Alaska Storms Program. Right: The two NOAA P-3's get de-iced at Brunswick Naval Air Station, Maine, as they prepare for a mission into a 'Noreaster during the Experiment on Rapidly Intensifying Cyclones over the Atlantic (ERICA) in 1989. Both photos taken by yours truly.

What is less appreciated is that these aircraft fly research missions into dangerous weather conditions year-round and world-wide, and some of the most dangerous flights have occurred far from the tropics. Earlier this year, Kermit experienced perhaps the most dangerous flight of its 31-year career. On February 9, the aircraft flew into an intense winter storm 500 miles east of Newfoundland. The mission was part of the Ocean Winds project, a study designed to test the accuracy of QuikSCAT satellite wind estimates in regions of high wind and heavy rain. Flying at 3,000 feet, the aircraft sampled the surface winds with its SFMR (Step Frequency Microwave Radiometer) and dropsondes. The flights were timed to coincide with an overhead pass of the QuikSCAT satellite, which also measured winds at the ocean surface. It was a bit of a rough ride, since the storm packed winds of 100-110 mph at flight level. Sea spray kicked up by the powerful winds reached all the way to flight level, coating the windshield with a thick white coating of salt. The windshield washer failed, leaving the windshield partially opaque. It was an unusually dry winter storm, and the rain showers needed to rinse the windshield clean were difficult to find.


Figure 2. QuikSCAT wind profile of the ocean surface at 21:22 GMT February 9, 2007, just before Kermit headed back to St. John's, Newfoundland.

After a successful 4-hour flight, the aircraft dropped its final dropsonde, and turned north to complete its final sampling run. Suddenly, crew members observed flames coming from the #3 engine, accompanied by an audible popping sound. "Fire on #3, flames, flames, flames!" came the cry over the on-board intercom system. The pilots and flight engineers immediately began an emergency shut down of the #3 engine. As they worked to shut down the engine, the ominous call, "Fire on #4!" came over the intercom. The pilot immediately began an emergency shut down of the #4 engine. With both engines on the right wing now shut down, the pilot cautiously ramped up power on the two engines on the left wing, turned the aircraft towards home base in St. Johns, Newfoundland, and attempted to climb. However, the aircraft was not able to climb on just two engines, and the pilot was forced to begin a gradual descent to 2600 feet. The pilot notified the crew to review their ditching placards, and word was send to air traffic control informing them of the emergency. Three tense minutes passed, as the crew attempted to figure out what had caused the multiple engine failures. Speculation centered on the unusually heavy accumulation of salt on the aircraft--but excessive salt had never been implicated in engine failures before. Then, the words they all dreaded, "Fire on #1!" burst out over the intercom. The flight engineer immediately pulled the emergency shutdown handle for the #1 engine, and Kermit began a 700 foot per minute descent towards the turbulent sea below.

The crew donned survival suits as the pilot issued a May-day distress call and prepared to ditch the aircraft. Beneath them, hurricane force winds blew over the night-shrouded North Atlantic waters. With waves easily reaching 20 feet, water temperatures near freezing, and 500 miles out at sea at night, prospects for survival were dim. Four minutes remained to restart one of the flamed-out engines, and the pilot called for an immediate restart of the #1 engine. As the flight engineer worked to comply, Kermit passed through a brief rain shower that washed considerable salt from the aircraft. The attempt to restart the #1 engine succeeded, and Kermit pulled out of its descent just 800 feet above the waves--one minute from impact.

The crew now worked to restart the failed #3 and #4 engines, while the plane slowly climbed away from the ocean surface. As they headed towards Newfoundland, the Canadian Air Force launched a search and rescue C-130 aircraft from Nova Scotia to intercept Kermit. Crews on the Hibernia and Terra Nova oil rigs located east of Newfoundland were alerted of the emergency, and stood by to help if necessary. Kermit's navigator continuously plotted vectors to the oil rigs at they flew home, in case a ditch near one of the rigs became necessary.

As they continued westward, the crew successfully restarted both the #3 and #4 engines, but at reduced power. Kermit climbed to a more comfortable altitude of 14,000 feet and made it uneventfully back to St. Johns. Fortunately, the engines were undamaged and perfectly operational after the salt was washed out, and the data collected during the mission was saved. According to the detailed NOAA Mishap Investigation Report posted on Chris Mooney's excellent blog, "Post flight inspection of engines revealed significant white build up on intakes, first stage compressors, and CIP probes of all four engines. Subjectively, the #2 engine appeared to be the worst coated of all engines. Aircraft fuselage and windows were also heavily coated." Salt build-up on the engines was determined to be the cause of the incident. The unusually dry nature of the storm prevented the salt from being washed off, and was probably part of the reason the engines failed on this flight, and not on previous flights.

I asked Dr. Jim McFadden, project manager of the Ocean Winds project, what happened. He was on the flight, and responded:

This event stumped everyone including the experts who spend a life-time studying sea salt and aerosols in the marine boundary layer. Six previous flights in similar conditions had resulted in nothing like this. But this one was different. It was flown over an ocean warmed by the Gulf Stream in a dry slot of cold Canadian air. Somehow that combination was the key to what could have been a disastrous flight. Fortunately, quick thinking and the flawless action of the crew brought about by excellent training got us home safely.

Last week in Washington D.C., the crew of Kermit was honored with the Department of Commerce's Gold Medal for successfully bringing home the aircraft. The crew members from NOAA's Aircraft Operations Center who were on the flight were:

LCDR Mark Nelson
LCDR Carl Newman
Joseph Klippel
LCDR Peter Siegel
LCDR Joseph Bishop
Tom Shepherd
James Barr
Terry Lynch
William Olney
James McFadden

QuikSCAT scientists Paul Chang and Rob Contreras were also present on the flight.

Separate Department of Commerce Gold and Silver Medals were also awarded last week for scientists involved in leading NOAA's operational use of NASA's QuikSCAT satellite to produce more accurate forecasts and warnings of marine and coastal weather:

Paul Chang
Hugh Cobb III (NWS)
Roger Edson (NWS)
James Franklin (NHC)
Richard Knabb (NHC)
Eugene Legg
Kevin Schrab (NWS)
Joseph Sienkiewicz (NWS)

A Gold Medal is defined as distinguished performance characterized by extraordinary, notable or prestigious contributions that impact the mission of the Department and/or one operating unit and which reflect favorably on the Department. Congratulations to all the awardees, and thanks for all that you do!

That's the point isn't it. If it ain't a Hurricane there's no chance it might blow a tree on your car or lawn furniture through your deck door/window.

Hmm lets see...65 knots of shear....absolutely no circulation, in fact it's anticyclonic, and SSTs are officially way too low to support tropical development.

Sorry I had to....lol.

I just read Dr Jeff's report on the Kermit.

I want to take a moment to give my gratitude to all of those who assist others on a daily basis. our military, both home and abroad. the US coast guard who pre 9/11 had a buget the size of some kids allowance??
To all of you out there who help us all go about our daily business with the freedoms that YOU provide for us.

to everyone out there,
please remember to love one another. we are all on this big round ball TOGETHER.

Happy Thanksgiving to all

SMILE!

V26R ~

Yeah, it's a cold one today for sure.
23 here in NW VT.
Are you down by Boston?
I have relatives there.
We've been having the cold for awhile now,
but I think you've had it gentler down that way.
It still seems a bit cool for the season.

Looks like Typhoon Mitag/Mina is veering off more to the north than anticipated yesterday.
Apparently the shift of both Typhoons is related to the ridge to the south that KoritheMan mentioned upthread.

Definitely one to watch!
It's good news for Manila and below,
but where will Typhoon Hagibis now go?

CENTRAL AMERICA AND THE CARIBBEAN REGION....

Upper diffluence is enhancing the development of scattered showers and isolated thunderstorms over the Northwest Caribbean and parts of Central America north of 14N. South of 14N strong diffluent flow is drawing moisture from the ITCZ across Caribbean from 75W to 65W south of 17N. The upper confluent pattern across the Eastern Caribbean is weakening and as this occurs low level moisture is beginning to move across the Islands from the Atlantic. Despite this, fair weather still remains across most parts. Winds have significantly increase across the Eastern-Central Caribbean over the past day or so south of a ridge north of the area. QuikSCAT shows a swath of 20-30 knot winds from the Islands to 80W. These winds are producing 10-15 ft seas in easterly swells.

Good Saturday to all


....SYNOPSIS....

GULF OF MEXICO/NORTHWEST ATLANTIC OCEAN WEST OF 40W....

Doppler radar over South-Central United States shows numerous showers and thunderstorms across Eastern Texas and Louisiana...also spreading over coastal waters of the Northwest Gulf. This activity is associated with a low pressure system and isentropic lift associated with an attached warm front. All this activity lies within a strong positive vorticity advection region ahead of an upper trough over the Rockies. Meanwhile, a cold frontal boundary continues to push southeastward across the Gulf and the Florida Peninsula. Most of the moisture along the front is in the form of multilayered cloudiness and showers due to moisture advection by upper winds.

A cold front enters the area near 38N/60W and extends southwestward to the Southern Tip of Florida at 25N/81W. Little shower activity accompanies the front south of 38N. Cold air stratiform clouds covers the area to the west of the front from 30N to Atlantic Canada.

As the cold front pushes off to the east, strong high pressure is building in behind resulting in exceptionally clear skies over the Southeastern United States. QuikSCAT and marine observations indicated that the high pressure system is producing fresh to near gale force northwest to northeast winds across Western Atlantic Ocean behind the cold front. These winds are producing 10-15 ft seas which are mainly offshore.

Now the remainder the Atlantic west of 40W remains under the influence of surface ridging and upper confluence west of an upper trough. Thereby shower activity remains low and fair weather dominates.

National Weather Service New Orleans la
456 am CST Sat Nov 24 2007


Short term...
today through Sunday night...a strong autumn storm system will be
bringing the threat of severe weather and heavy rain to the
forecast area on Sunday and Sunday night. Water vapor loops show a
deepening middle/upper trough and closed low digging in over the
southwest Continental U.S. And northwest Mexico while a belt of increasing
upper level winds sets up in southwest flow over Texas...the lower
MS valley...and the northwest Gulf. Minor disturbances will ride
east-northeast along this belt of winds today and tonight as the
upper low moves east-southeast/east into southwest Texas and the
Rio Grande Valley. A large dry and cool Continental low level
airmass over most of the eastern half of the Continental U.S. Will erode as
a trough of surface low pressure/warm front expands from off the
Lower Texas coast towards the Louisiana coast late tonight. Radar
already shows areas of rain and sprinkles west and north of Lake
Pontchartrain...and rain will continue to increase through the day
and into this evening aided by isentropic lift/warm air advection.


By late tonight...elevated instability due a strengthening
southerly 850 mb jet may cause some isolated thunderstorms to
mix in with the rain shield. Strong directional and speed shear
will be in place...and radar will likely be detecting rotation
elevated storms during the midnight to 6 am period...especially
near the south central/southeast la coast. Severe weather is not
expected through tonight due to the elevated nature of the storms.


Sunday...the area of surface low pressure and a warm front will be
drawn northeast into Louisiana. The 06z NAM and GFS take this low
west of our forecast area...across southwest into northeast la.
The 00z European model (ecmwf) is farther east and a bit slower with the surface
low...taking the low through the middle of southeast la and across
south central/ southeast Mississippi Sunday afternoon and evening
with the cold front passing through our area Sunday night. The
upper low/trough will be taking on a negative tilt as it moves
northeast through the arklatex Sunday night. There is a chance of
all types of severe weather...wind...hail and isolated tornadoes
with both the warm front and ahead of the cold front Sunday and
Sunday night...with the greatest threat in the warm sector ahead
the cold front Sunday afternoon and Sunday night. A general
soaking to heavy rainfall event is expected. A general 2 to 3
inch swath with local amounts up to 5 inches is expected over
areas generally along and northwest of a line of McComb to the
Baton Rouge area. Areas to the east could also receive heavy
rainfall up to 2 inches with locally higher amounts...but the line
of thunderstorms and heavy rain will be moving a bit quicker
through this area.




Anyone traveling through the lower MS valley/central Gulf Coast
region this weekend...especially on Sunday...should pay close
attention to the latest forecasts and have a National oceanic and atmospheric administration weather radio or
other notification device to receive any possible hazardous
weather alerts/warnings.

The following data does not include any "peak strength" for Mitag in progress, expected to cross the threshold of Major Hurricane in the next hours. Because Mitag is not yet counted either over nor under that threshold, the percent numbers do not add up to 100%, and won't until some peak is established to categorize the storm.

As it stands, Hagibis is now historic as the third category 2 hurricane in the world in 2007. I personally would have counted Krosa and Sidr as cat 5s, but the keepers of the official records do not. Still going by those records there were more cat 5s than cat 2s. There were also more "major hurricanes" (3, 4 or 5) than "minor" ones (1 or 2), validating a global warming prediction that storm intensities will increase with more high-end storms.

The jetstream to the north of the two typhoons is certainly doing the steering.

Both cyclones are changed directions from due west.

If you look up at post #183 you can see what's doing the steering, and if you put the last 24 hours in motion in an animation you will see a very brisk wind that even hurricanes can't ignore.

Try to pay attention to where that wind is piling on the moisture airlifted by these heat engines. That red-orange cloud at 160-170W, 30N is the accumulation of days of outflow piling on right behind SIDR's accumulated outflow.

SIDR's outflow remnants broke into two branches, one of which battered southern Alaska on Thanksgiving and the second swirling west of the Aleutian Islands. Both Mitag & Hagibis are now contributing to that unseasonably warm airmass which rained 15 inches in a day off Alaska.

The "great circle route" is the shortest line between any two points on the globe. The shortest path that cuts from Hagibis/Mitag through British Columbia goes on to Nashville Tennessee. Expect flash floods and tornadoes thereabouts next week.

Whoa, what the heck? Hagibis's track is now shifted to where Mitag is.

It was near landfall, and is now turning eastward due to a ridge to its south (if I read the discussion right).

Talk about weird. O_o

Tigers add to their worries

The cyclone-struck people of Southkhali union in Bagerhat had a new worry Thursday night when two Royal Bengal tigers entered Sonatala village and the Sharonkhola Forest Office.

The tigers created panic among the people of the union who have been virtually living under the open sky as Sidr destroyed their homes.

The district forest officer (DFO) said the forest guards were trying to locate the tigers. They would be driven back to the forest, he added.

DFO SM Shahidullah said 33 carcasses of deer were recovered till Thursday. But they have not yet recovered any tiger carcasses.

Surviving the aftermath of Cyclone Sidr

"We all thought that we were going to die," says Asia, 40. When she talks about the night that Cyclone Sidr annihilated both her home and her village, the traumatic shock is visible in her eyes.

"We didn't think," she says. "We just held on to anything that was there." Asia counts off the material cost of the disaster: five cows, four goats, and her home. Two days after the storm, she also found the body of her niece, who had been carried nearly three kilometers (2 miles) by the storm surge.

The villagers in Katachira have managed to recover 70 bodies. At least 200 people are still missing, and the body of another child, a little girl was discovered only a day ago. The major concern in the days immediately following the cyclone was how to bury children, wives and husbands, properly when nothing was left .

Like others who survived, Asia managed to resist the sea surge following the storm by holding on to a tree. Another family survived miraculously with 15 members hanging on to branches of the same tree. The few cattle and goats who survived, were also caught by tree limbs, according to the villagers, and managed to keep their heads above the water.

Khatachira is near one of the largest mangrove forests in the world. As the level of the water rose, eventually approaching 5 meters (16 feet) higher, the villagers held on to higher and higher branches of the trees. When the water level finally dropped, after about five or six hours, some people were clinging to branches that were so high off the ground that they didn't know how to get back down.

Abdul Kudos, 68, who lost his fishing boat and means of earning a livelihood, says he can't remember what actually happened, or how he managed to survive.

Feroza, 35, who lives in the same village, lost nearly everything that she had. She tried to hold on to a tree, but was swept two kilometers (1.5 miles) away from the village. Her two-year old daughter drowned. Her five cows perished. Her clothes were torn from her body by the force of the current. She had to borrow new clothes from a neighbor. Today she lives and sleeps on an open patch of ground where her house once stood like many of her neighbors in Katachira.

Most of the survivors in what is left of Khatachira feel that it is a miracle that they are alive. But in an ironic twist of fate the fact that so many people survived this cyclone in comparison to earlier ones, means that there are many more people who are in desperate need of food and support than in previous storms.

Bangladesh now faces an immense challenge in trying to keep the survivors alive. The fishing boats that used to provide food for Katachira were smashed by the storm. The 200 or more houses that once made up the village were swept away, in many cases without leaving any trace that they were ever there. The market that people relied on for food is gone, and no one has any money to pay in any case. The government dropped off some rations a few days after the storm, but they were gone in a day.

For many people the period after the storm promises to be just as dangerous and demanding as surviving the storm itself. Polluted water will begin to spread dysentery if effective action is not taken quickly. Two small children have already died from an outbreak of diarrhea, and more will very likely follow soon. Khatachira's only source of water is a stagnant pond, filled with blackened leaves.

CARE is distributing both food and essential non-food materials needed for survival. But whether these efforts will be sufficient, will depend largely on donors and the public providing sufficient funding to reach the largest number of people possible. In the meantime, people in the places that were most heavily damaged by the storm, know that they can't survive a long wait for help to come. "We were able to cook some food yesterday," says Asia, "but we don't know what will happen today or tomorrow."

A large area of dry air and dust has exited Africa, and extends to 30w. That should dry up any moisture in the Tropical Atlantic, not that there is much to speak of.

nothing is really wrong with them but it may have someone out there who does know how to read a skew-t chart or detect a front using infrared imagery. But I'm glad u understand them

....SYNOPSIS....

GULF OF MEXICO/NORTHWEST ATLANTIC OCEAN WEST OF 40W....

A cold front continues to push southeastward across the Gulf and Western Atlantic from the Isthmus of Tehuantepec...across Southern Florida. The front is accompanied by scattered cloudiness with light to moderate precipitation. Surface high pressure has build in behind the front across the Southeastern United States, extending down into Mexico where the ridge is dammed against the Sierra Madre Mountains. Elevated convection along with patches of fog and low level precipitation exist within the low valleys of Mexico and lowlands of Central Texas from 20N to 35N.

The cold front continues from Southern Florida along 30N/71W 32N/70W to beyond 35N/65W. Light to moderate showers exist within a 120 nm band of cloudiness along the front. Elsewhere over the Atlantic is dominated by surface ridging and thus fair weather exist. The increasing pressure gradient between the ridge and the low in the North-Central Atlantic has increase the wind and wave action along the Atlantic coasts of the Caribbean Islands Chain. See Caribbean section.

CENTRAL AMERICA AND THE CARIBBEAN REGION....

Scattered showers and isolated thunderstorms are over Central America and the immediate Caribbean Sea in associated with the sea breeze circulation and the ITCZ near 10N which are being enhanced by upper diffluence in the left entrance region of an upper ridge. Currently, that is the only disturbed weather to speak of over the region. Fair weather dominates the remainder the Caribbean due to opposite effects. Confluent flow aloft in the right exit region of an upper ridge is bringing dry stable air over the area leading to much subsidence and fair weather dominates.

The cold front moving over the Western Atlantic is pushing a high pressure ridge against the low pressure system in the North-Central Atlantic causing the pressure gradient to tighten over the area. 20-30 knot winds and 16 ft seas are impacting the Atlantic coast of the Leeward Islands, Puerto Rico, Hispaniola and the Bahamas. Small craft advisory remains in effect over these waters. Seas are relatively light over the coast of Cuba due to protection of the Bahamas Islands which are technically aged coral reefs. Conditions remain suitable for marine activities over these waters.

High pressure is also increasing the trades through the Caribbean with the highest trades over the Southwest Caribbean Sea. 7-10 ft seas in east-northeast swells from the Islands to 80W south of 19N.

That Bering low is going to spawn a triple-point system that will move into my area in 2-3 days.

Yeah I guess it has been a while.

That site is for the first image. I have that one lol. To make it simple, I'm looking for the site that you get the images from that have the little cross-hairs for the lat/lon markings, instead of lines.

Hello to everyone out there today. After a bonechilling 12 degree start to the the day, we warmed up just enough to make the snow coming down a little more enjoyable. I always enjoy the first snow! The fire is crackling and the house smells so good.
