The new hottest place on Earth: Death Valley, California

As any weather aficionado can avow, Earth's most iconic weather record has long been the legendary all-time hottest temperature of 58°C (136.4°F) measured 90 years ago today at El Azizia, Libya on September 13, 1922. One hundred thirty six degrees! It's difficult to comprehend that heat like that could exist on our planet. For 90 years, no place on Earth has come close to beating the unbelievable 136 degree reading from Al Azizia, and for good reason--the record is simply not believable. But Earth's mightiest weather record has been officially cast down. Today, the official arbiter of Earth's weather records, the World Meteorological Organization (WMO), announced that the all-time heat record held for exactly 90 years by El Azizia in Libya "is invalid because of an error in recording the temperature." The WMO committee found five major problems with the measurement. Most seriously, the temperature was measured in a paved courtyard over a black, asphalt-like material by a new and inexperienced observer, not trained in the use of an unsuitable replacement instrument that could be easily misread. The observer improperly recorded the observation, which was consequently in error by about 7°C (12.6°F.) The new official highest hottest place on the planet is now Death Valley, California. A remarkable high temperature of 56.7°C (134°F) was measured there on 10 July 1913, at Greenland Ranch.


Figure 1. The trading post at Al Azizia, Libya in 1923. The photo was taken from the Italian military fort located on a small hill just south of the trading post. It was at this fort that the temperature of 58°C (136.4°F) was observed on Sept. 13, 1922 (used with permission from the family of Gen. Enrico Pezzi).

The story behind the overturning of Earth's most hallowed weather record
Today's announcement is the culmination of a 3-year research effort begun by wunderground weather historian, Christopher C. Burt. His blog post today, World Heat Record Overturned--A Personal Account, provides a fascinating detective story on how the record came to be cast down--and how the Libyan revolution of 2012 almost prevented this from happening.

Dead Heat: The Video
Don't miss the 25-minute wunderground video, Dead Heat, a detective story on how the El Azizia record was overturned.

Atlantic tropical update
Tropical Storm Nadine is recurving to the northwest and north well east of the Lesser Antilles Islands, on a track that would likely keep this storm far out at sea away from any land areas. However, Nadine may eventually threaten the Azores Islands or Newfoundland; the models are divided on how the steering currents will evolve next week, and we cannot be sure which way Nadine will go during the middle of next week.

The models predict that a trough of low pressure off the U.S. East Coast may serve as the focus for development of a non-tropical low pressure system on Sunday or Monday, but this low will likely form too far to the north to become a tropical storm. The GFS model has been predicting a tropical wave coming off the coast of Africa may develop next week, but has not been consistent with the timing or location of the development.

In the Western Pacific, Super Typhoon Sanba is an impressive top-end Category 4 storm with 155 mph winds, and is headed north-northwest towards a possible landfall in Korea early next week.

Given the importance of the new world record all-time high temperature, I'll leave this post up until Saturday afternoon, when I'll post an update on the tropics.

Good Morning to everyone, first rain here outside Buda Tx in 61 days this morning, rec. about 1 inch so far, Lake Travis which is down 50 feet went up 4 inches since yesterday. Still think this state needs tropical rains because this drought around here has been going on for years.

Puerto Rico NWS

AN ACTIVE TROPICAL WAVE...CURRENTLY NEAR 45 WEST LONGITUDE EARLY
THIS MORNING...IS EXPECTED TO APPROACH THE REGION BY TUESDAY OR
WEDNESDAY NEXT WEEK. THIS WAVE IS FORECAST TO BRING ACTIVE WEATHER
ACROSS THE LOCAL AREA. LATEST MODEL GUIDANCE INDICATED PW VALUES
WILL INCREASE UP TO 2.25 INCHES WITH THE PASSAGE OF THIS WAVE.
THEREFORE...A MORE UNSETTLED WEATHER IS FORECAST TO DOMINATES THE
NORTHEAST CARIBBEAN NEXT WEEK...COMPARED TO THE PREVIOUS 2 WEEKS
OF THE MONTH WHICH HAVE BEEN VERY DRY AND HOT. ACROSS THE TROPICAL
ATLANTIC...OTHER THAN TROPICAL STORM NADINE WHICH IS MOVING OVER
THE OPEN WATERS...NO DEVELOPMENT ARE FORECAST IN THE NEAR FUTURE.

Yes, for my independent study but I don't mind writing them at all. I'll be writing one every single day, that's the writing portion.

Another rather amazing observation for this date, 9/14/12, is the North Pole Web camera #1 showing water droplets on its lens. These may be frozen droplets; that is impossible to discern but that they arrived on the lens as liquid attests to quite warm temps at the top of the world. The picture also shows some of the melt ponds as not yet snowed over.



In one week the sun will depart from the pole for the six months of winter and now is just barely above the horizon.

the NOGAPS does well on the genesis of storms especially when it comes to the the east caribbean..we will see if it outperforms the models again..
Okay but I give it a 10% chance of doing so.And that's being generous :).

Good Morning...

Keep watching P28L this could be a player in the W Carib to NW Carib to Bahamas. Location/development would depend on its direction of displacement.

LOCATED OVER THE CENTRAL TROPICAL ATLANTIC ABOUT 1100 MILES EAST OF
THE WINDWARD ISLANDS. HOWEVER...ENVIRONMENTAL CONDITIONS DO NOT
APPEAR CONDUCIVE FOR SIGNIFICANT DEVELOPMENT WHILE THE WAVE MOVES
WESTWARD AT ABOUT 15 MPH DURING THE NEXT COUPLE OF DAYS. THIS
SYSTEM HAS A LOW CHANCE...10 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

As of 9/13/12, The Cryosphere Today web site showed a low in sea ice extent over 22% lower than the record minimum set in any previous year.



This could greatly change the temperature regime of the Arctic Ocean and increase the release of methane gases from subsea deposits. That will be another positive feedback for global warming causing greater climate instability for the future.

Is this the "story of the year" that the main stream media chooses to ignore?

TODAY THROUGH SATURDAY AND SUNDAY...AS A SERIES OF DISTURBANCES
PASS OVER THE REGION IN ADVANCE OF THE LOW OVER THE SOUTHWEST U.S.
THE FINAL PERIOD OF RAIN IS EXPECTED ON SUNDAY...AS THE LOW MOVES
OVER SOUTH CENTRAL TEXAS FROM THE WEST. LOCALLY HEAVY RAIN IS
POSSIBLE WITH THESE WEATHER PATTERNS THROUGH SUNDAY. RAINFALL
AMOUNTS OF 1 TO 2 INCHES IS EXPECTED...WITH ISOLATED RAIN AMOUNTS
OF 3 TO 5 INCHES. THIS MAY CAUSE MINOR FLOODING ACROSS STREETS...
UNDERPASSES...LOW WATER CROSSINGS AND ALONG SMALL STREAMS AND
RIVERS.

DRIER WEATHER IS EXPECTED SUNDAY NIGHT AND MONDAY...AS THE RAIN
MAKING WEATHER SYSTEM MOVES EAST OF SOUTH CENTRAL TEXAS.
A MOSTLY SUNNY DAY IS EXPECTED MONDAY.

Well I'm off for awhile, looks like on visible in motion that P27L doesn't care what the models think. It appears to be forming a depression to me.

One thing you can say about P27l is it is not trying to form up the whole Atlantic at one time. I just find it interesting the NHC puts a circle on the tip of Fl. the other day and doesn't circle P27l. But that's how much respect these models demand and to some extent they have earned it. I just like to look for things that may spring up. Also was hoping the N Antilles would get a rain from the system, as they seem to be in need of it.

Quoting Grothar:


I think these models are based on a tropical wave that is expected to move south of Nadine and interact with here; a sort of Fujiwhara scenario where the wave slings Nadine back west.





Morning, Gro,

Probably more likely, or at least an alternate explaination is the GFS based FIM is having some problems handling Nadine's interaction with the deep-layer cut-off low to the east and a replacement cut-off forming up to the west towards the middle of next week. Models that show a re-re curve back to the west depict Nadine becoming entrained in the cyclonic circulation around the "replacement ULL. A T-wave might not have enough "reach" to cause the FIM track.

The simplest solution would have Nadine follow in the wake of the eastern ULL, stall over the Azores and eventually become absorbed into its circulation. The 06Z GFS operational has backed off on a western tracking slingshot.

Interesting steering possibilities in any case.

SAL is pretty much in check for the time being:



Which helps explain which P27L still at it too.
