February 2012 was the globe's 22nd warmest February on record, according to the National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC). Global temperatures were the 15th warmest on record according to NASA. It was the coolest February since 1994, and the coolest month, relative to average, since January 2008. The relatively cool temperatures were due, in part, to the on-going La Niña event in the Eastern Pacific, which has brought a large amount of cool water to the surface. February 2012 global land temperatures were the 37th warmest on record, and ocean temperatures were the 12th warmest on record. Global satellite-measured temperatures for the lowest 8 km of the atmosphere were colder than average, the 7th or 13th coldest in the 34-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH). February temperatures in the stratosphere were the coldest on record. We expect cold temperatures there due to the greenhouse effect and to destruction of ozone due to CFC pollution. Snow cover during February varied dramatically depending on which hemisphere you were in. Eurasia had its third largest snow cover extent in the 46-year period of record, while North America had its fourth lowest. As seen in Figure 1, much of North America and Siberia were much warmer than average, while Europe was considerably colder than average. Wunderground's weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of February in his February 2012 Global Weather Extremes Summary.

La Niña weakens, almost gone
A borderline weak La Niña event continues in the equatorial Pacific, where sea surface temperatures were approximately 0.5°C below average during February and the the first half of March. NOAA's Climate Prediction Center forecasts that La Niña will be gone by the end of April. The majority of the El Niño computer models predict neutral conditions for this fall, during the August - September - October peak of hurricane season, though 32% of the models predict an El Niño will develop. El Niño conditions tend to decrease Atlantic hurricane activity, by increasing wind shear over the tropical Atlantic.

February Arctic sea ice extent fifth lowest on record
Arctic sea ice extent was at its fifth lowest extent on record in February, according to the National Snow and Ice Data Center. Continuing the pattern established in January, conditions differed greatly between the Atlantic and Pacific sides of the Arctic. On the Atlantic side, especially in the Barents Sea, air temperatures were higher than average and ice extent was unusually low. February ice extent for the Barents Sea was the lowest in the satellite record, due to air temperatures that ranged from 4 - 8°C (7 - 14°F) above average at the 925 mb level (about 3000 feet above sea level). In contrast, on the Pacific side, February ice extent in the Bering Sea was the second highest in the satellite record, paired with air temperatures that were 3 to 5 degrees Celsius (5 to 9 degrees Fahrenheit) below average at the 925 mb level. Satellite sea ice records date back to 1979.

Huge hailstone sets Hawaii record
A hailstone with the diameter of roughly that of a grapefruit that hit Oahu on March 9, 2012, has been confirmed as the largest hailstone on record for the state of Hawaii, according to NOAA. The record-setting hailstone was dropped by a “supercell” thunderstorm on the windward side of Oahu. There were numerous reports of hail with diameters of 2 to 3 inches and greater. Hail the size of a penny (diameter of 3/4 inch) or quarter (diameter of one inch) has been reported in Hawaii only eight times since records began, and there is no record of hail larger than 1 inch in diameter. Hail the size of golf balls and baseballs can only form within intense thunderstorms called supercells. These supercells need warm, moist air to rise into progressively colder, drier air, as well as winds changing direction and increasing speed with increasing height off the ground. For both sets of conditions to exist at the same time in Hawaii is extremely rare, but that did occur on March 9. Conditions that day were ideal for a supercell to form, and the storm looked very much like supercell thunderstorms common in the Central U.S. during spring. Supercells can also produce tornadoes, another rarity in Hawaii. The same hail-producing supercell produced a confirmed EF-0 tornado with winds of 60-70 mph in Lanikai and Enchanted Lakes on Oahu.

...DISCUSSION...
GFS AND ECMWF HAVE COME INTO DECENT AGREEMENT THROUGH ROUGHLY DAY 5
/MON 4-2/ WITH RESPECT TO HANDLING OF THE EJECTING WRN SYSTEM...BUT
DEVIATIONS FROM DAY 6 /TUE 4-3/ ONWARD -- AS THIS SYSTEM CROSSES
AREAS NEAR AND E OF THE APPALACHIANS -- RESULT IN FORECAST
UNCERTAINTY FOR THE LATTER 2/3 OF THE PERIOD.

WHILE SOME SEVERE POTENTIAL MAY EXIST DAY 4 /SUN 4-1/...PRIMARILY
NEAR A WARM FRONT INVOF THE UPPER MS VALLEY...LARGE-SCALE RIDGING
STILL IN PLACE WITH THE MAIN SYSTEM STILL OVER THE ROCKIES SUGGESTS
THAT ANY THREAT WILL REMAIN LIMITED.

MORE SUBSTANTIAL SEVERE THREAT APPEARS LIKELY TO EXIST DAY 5...AS
THE UPPER TROUGH EMERGES INTO THE PLAINS...AND A COLD FRONT SWEEPS
EWD ACROSS THE PLAINS EARLY IN THE DAY...AND REACHES A POSITION FROM
ROUGHLY THE UPPER MS VALLEY SSWWD ACROSS MO AND INTO E TX.
WHILE
SOME THREAT WILL LIKELY EXIST AS FAR N AS THE UPPER MIDWEST/UPPER
GREAT LAKES REGION...GREATEST POTENTIAL APPEARS LIKELY FROM THE
OZARKS SWD/SEWD TO THE WRN AND CENTRAL GULF COAST REGION.
HERE...STRONG SHEAR AND AMPLE INSTABILITY SUGGEST FAIRLY WIDESPREAD
SEVERE POTENTIAL...WITH SUPERCELL ORGANIZATION LIKELY AND ASSOCIATED
THREATS FOR WIND/HAIL AND POSSIBLY ISOLATED TORNADOES.
THREAT WILL
SPREAD EWD WITH TIME...POSSIBLY REACHING THE TN VALLEY AND AL DURING
THE EVENING/OVERNIGHT.

THE SURFACE FRONT ASSOCIATED WITH THIS SYSTEM IS PROGGED SHIFT EWD
ACROSS THE ERN U.S. DAY 6...AND WILL LIKELY HAVE MOVED TO/OFF THE
ATLANTIC COAST BY THE END OF THE DAY 6 PERIOD...WITH THE UPPER
TROUGH AXIS FOLLOWING SHORTLY THEREAFTER. AGAIN HOWEVER...WITH

AREALLY HIGHLIGHT ANY THREAT AREAS WHICH MAY BE EVENTUALLY ADDED
NEAR/E OF THE APPALACHIANS. WITH LARGE-SCALE/PERSISTENT RIDGING
FORECAST ACROSS THE CENTRAL U.S. IN THE WAKE OF THIS SYSTEM...A LULL

Surely you can not achive over saturation, once you have 100 % saturation, you can't add any more.

Kind of interesting, and I'm surprised that no one has thought of an acoustic mirage.

Sound can do strange things, sometimes due to temperature inversions, and since these events are all happening about the same time of the evening ... I think; I wouldn't rule out the possibility.

You can have acoustic shadows, as well, and these make for an interesting read.

It's still a little unnerving, however.

The critters are having a hard enough time trying to survive around Man's margins.
The last thing they need is for even more people to lose empathy/sympathy for their plight because their names are associated with hurricanes.

Pret much would hafta look that way for any substantial flow rate...

...the seabed is only 305feet(93metres) down.
Not much headroom for mixing&diffusion before reaching the surface.

It appears that things at Fukushima are not going according to either plan or press release; news soucres this evening are reporting that radiation levels in Unit #2 are at an insanely high 73 sieverts per hour--the highest they've been since last year's earthquake. (To illustrate how high that is: nuclear workers can be exposed to roughly 20 millisieverts of radiation per year; Unit #2 is at about 640 million times that level. A worker in Unit #2 would receive 20 years' worth of radiation each second. Meaning that, yes, working there would kill someone within minutes.) Unit #2's containment vessel was supposed to have 10 meters of water in it, but was found instead to be holding only 60 centimeters.

Conditions in Unit's #1 and #2 aee still unknown, as neither workers, robots, nor arthroscopes have been able to get a close picture.

Sure sounds like an "everything's under control, cold shutdown" scenaro to me...

Anti-science legislation offers prospect of a new Scopes trial

lmost 90 years ago, Tennessee became a national laughingstock with the Scopes trial of 1925, when a young teacher was prosecuted for violating a state law forbidding the teaching of evolution. With the passage of two bills, House Bill 368 and Senate Bill 893, the Tennessee legislature is doing the unbelievable: attempting to roll the clock back to 1925 by attempting to insert religious beliefs in the teaching of science.

These bills, if enacted, would encourage teachers to present the “scientific strengths and scientific weaknesses” of “controversial” topics such as “biological evolution, the chemical origins of life, global warming, and human cloning.” As such, the bills are misleading, unnecessary, likely to provoke unnecessary and divisive legal proceedings, and likely to have adverse economic consequences for the state.

MEDIUM-RANGE MODELS CONTINUE TO DEPICT THE EWD EJECTION OF A
SUBSTANTIAL CHUNK OF THE PERSISTENT NERN PACIFIC UPPER
SYSTEM...SHIFTING ACROSS THE INTERMOUNTAIN WEST DAY 4 /SAT 3-31/ AND
THEN INTO THE PLAINS DAY 5. HOWEVER...SIGNIFICANT DIFFERENCES
PERSIST BETWEEN THE TWO MODELS...EVEN MORESO THAN THE MODEL RUNS
FROM 24 HOURS AGO.

WHILE THE PASSAGE OF THIS SYSTEM ACROSS THE CENTRAL -- AND
EVENTUALLY THE ERN/NERN U.S. -- WOULD LIKELY BE ACCOMPANIED BY
FAIRLY SUBSTANTIAL SEVERE POTENTIAL...THE DIFFERENCES IN TIMING AND
EVOLUTION OF THIS SYSTEM AS DEPICTED IN THESE TWO MODELS CAST
CONSIDERABLE DOUBT AS TO EVEN ROUGH APPROXIMATIONS OF TIMING AND
LOCATION. THE ECMWF APPEARS SUBSTANTIALLY MORE ROBUST WITH RESPECT
TO SEVERE POTENTIAL -- PARTICULARLY BEYOND DAY 4...WITH ITS MUCH
SLOWER/NEGATIVELY-TILTED PROGRESSION OF THE TROUGH INTO THE PLAINS
AS OPPOSED TO THE GFS WHICH SHIFTS A MUCH FLATTER SYSTEM QUICKLY EWD
ACROSS THE N CENTRAL U.S./GREAT LAKES REGION. GIVEN THE DEGREE OF
MODEL DIVERGENCE...WILL ONCE AGAIN FOREGO AN AREAL HIGHLIGHT THIS
FORECAST.

Tough crowd on FB tonight. Maybe we want to be gentle here and discuss global warming?

Hope all is well with everyone.

NOLA Disco,Long term,

Area forecast discussion
National Weather Service New Orleans la
826 PM CDT Wednesday Mar 28 2012



Long term...
a strong shortwave trough will move into California on Saturday as
a pair of shorwaves move across the eastern Seaboard and central
Gulf Coast region. A flat middle level ridge will move into the
central states. The lingering shortwave trough will bring
lingering shower and thunderstorm chances on Saturday...but this
may be more in the morning than afternoon. The middle level ridge
will move over the central Gulf Coast on Sunday...so any slight
rain chance should be confined to the coastal waters.


The operational models have gone back to a stronger shortwave
trough that moves from The Rockies into the plains Sunday night
and early Monday and the Mississippi Valley late Monday and Monday
night. This is similar to the stronger ensemble runs from
yesterday. Have maintained a slight chance of showers and
thunderstorms for now...but if the stronger model runs continue
that pop will go up with future forecasts. A fairly strong cold
front should move through Monday night followed by drier and
cooler air Tuesday and Wednesday.

I wish we had names like those of the 1950's for storms in the Atlantic during hurricane season.They were as we say.....more catchy.
