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.

Based on the forecast longwave pattern, a large amplitude trough is forecast to become extant over much of the southern and eastern United States next week. Based on that, my guess right now on any United States areas would be Florida (don't fantasize about this too strongly, Janiel), although a weaker system could come more west. An alternative scenario is for it to remain south of the weakness and move into Central America.

You have a penchant for the trenchant.

...
His Puissant Sword unto his side
Near his undaunted Heart was ty'd,
With Basket-hilt, that wou'd hold broth.
And serve for Fight, and Dinner both.
In it he melted Lead for Bullets,
To shoot at Foes, and sometimes Pullets ;
To whom he bore so fell a Grutch,
He ne'er gave quarter t' any such.
The trenchant blade, Toledo trusty.
For want of fighting was grown rusty,
And eat into it self, for lack
Of some body to hew and hack.

The peaceful Scabbard where it dwelt,
The Rancor of its Edge had felt :
For of the lower end two handful,
It had devoured 'twas so manful ;
And so much scorn'd to lurk in case,
As if it durst not shew its face.
In many desperate Attempts
Of Wars, Exigents, Contempts,
It had appear'd with Courage bolder
Than Sergeant Bum, invading shoulder.
Oft had it ta'en possession.
And Pris'ners too, or made them run.
This Sword a Dagger had his Page.
But was but little for his age :
And therefore waited on him so,
As Dwarfs upon Knights Errant do.
It was a serviceable Dudgeon,
Either for fighting or for drudging ;
When it had stab'd or broke a head.
It would scrape Trenchers, or chip Bread,
Toast Cheese or Bacon, though it were
To bait a Mouse-trap, 'twould not care.
...

From spaceweather.com

In this wide-angle view, Blanchard captured the exhaust from both missiles. "The crescent Moon overhead was a beautiful bonus," he says.

As the rockets raced through the high atmosphere, water vapor in their exhaust crystalized to form tiny ice crystals. The crystals diffracted the light from the rising sun to produce the iridescent colors.
Nice Pic etxwx. Living close to to KSC I have seen similar from my front yard, but as often happens I forget to actually get out ahead of time to watch, so by the time the low rumble shakes my house all I can see is the exhaust trail...the rocket is already out of sight.
P.S. Never saw two go off at once though!

HURRICANE NADINE DISCUSSION NUMBER 15
NWS NATIONAL HURRICANE CENTER MIAMI FL AL142012
1100 PM AST FRI SEP 14 2012

NADINE HAS GOTTEN BETTER ORGANIZED OVER THE PAST FEW HOURS...WITH
THE CORE CONVECTION BECOMING MORE SYMMETRICAL AND MICROWAVE IMAGERY
SHOWING THAT THE LOW-LEVEL CENTER IS LOCATED A LITTLE CLOSER TO THE
DEEP CONVECTION. SATELLITE INTENSITY ESTIMATES RANGE FROM 65 KT
FROM TAFB TO 77 KT FROM SAB AND THE UW-CIMSS ADT. GIVEN THAT SOME
TILT STILL APPEARS TO EXIST IN THE CIRCULATION...THE INITIAL
INTENSITY WILL BE BASED ON THE MORE CONSERVATIVE ESTIMATE FOR THIS
ADVISORY. SOUTHWESTERLY VERTICAL SHEAR OF 25 TO 30 KT IS AFFECTING
NADINE...AND THIS MODERATE TO STRONG SHEAR IS FORECAST TO CONTINUE
FOR THE NEXT SEVERAL DAYS. GIVEN THIS MARGINAL ENVIRONMENT...ONLY
MINIMAL STRENGTHENING IS FORECAST IN THE SHORT TERM. LATE IN THE
PERIOD...THE CYCLONE WILL BE MOVING OVER COOLER WATERS...WHICH IN
COMBINATION WITH EVEN STRONGER SHEAR SHOULD LEAD TO GRADUAL
WEAKENING. THE NEW NHC INTENSITY FORECAST IS CLOSE TO THE DECAY
SHIPS MODEL THROUGH 72 HOURS AND TRENDS TOWARD THE LGEM BY DAY 5.

THE INITIAL MOTION ESTIMATE IS 025/12...AS NADINE IS MOVING AROUND
THE NORTHWESTERN SIDE OF THE SUBTROPICAL RIDGE. THE CYCLONE WILL
ENTER THE MID-LATITUDE WESTERLIES WITHIN 24 HOURS...WHICH SHOULD
RESULT IN A QUICK EASTWARD MOTION UNTIL ABOUT DAY 3. A SLOWER
MOTION TOWARD THE NORTHEAST IS EXPECTED AT DAYS 4 AND 5 AS AN
UPPER-LEVEL TROUGH APPROACHES FROM THE WEST. THE GLOBAL MODEL
GUIDANCE IS IN GENERALLY GOOD AGREEMENT ON THIS SCENARIO...WHILE
THE REGIONAL HURRICANE MODELS APPEAR TO BE OUTLIERS AT THIS TIME.
THE NHC FORECAST IS LARGELY AN UPDATE OF THE PREVIOUS ONE...BUT
WITH A FASTER FORWARD SPEED THROUGH 72 HOURS. THE NEW NHC TRACK IS
VERY CLOSE TO A BLEND OF THE GFS...ECMWF...UKMET...AND THE GEFS
ENSEMBLE MEAN...AND LIES NEAR THE MIDDLE OF THE GUIDANCE ENVELOPE.

NADINE MARKS THE THIRD-EARLIEST FORMATION OF AN EIGHTH HURRICANE FOR
THE SEASON IN THE ATLANTIC BASIN...BEHIND 1893 AND 2005.
