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.

SAL is pretty much in check for the time being:



Which helps explain which P27L still at it too.

Concerning p28L that's the most moisture I have seen in front of one of these waves this year.

Quoting WxLogic:
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.


Yeah that's the wave to watch, plus there are a couple more behind that one.

But you are right Wxlogic down the road p28l is low enough to cause some trouble.

Sanba has been tweaked west slightly, showing a path more directly over Korea. The west coast of Korea is more heavily populated than the east coast. Seoul is one of the largest cities in the world (metro 23 million) and has a very pronounced rainy season from June to mid-September, and is winding up a fairly wet season in which they have had about 20 inches of rain in the past five weeks. Needless to say, nearby Pyongyang in North Korea is a constant disaster waiting to happen.

Good morning. EWRC occuring with Sanba:



It's still listed as a 150kt Cat 5, but that's probably too high at this point. Hopefully the timing of this EWRC works out so that it never recovers and continues to weaken before impacting land.

Good morning MA, yeah I don' think Sanba is a cat5 right now too.

Quoting aislinnpaps:
Good morning, everyone. My thoughts and prayers to those in the path of Sanba. That is one wicked storm.

Good morning aislinnpaps, I hope it weakens more so that it's impacts aren't as bad.

Where is Kori tonight?


Remember what I said yesterday about going to work on no sleep? Well I ended up doing it. Slept from 7:30 to 8:30, went to work at 9. Even then, it wasn't really "rest", it was more casual dosing off then realizing "Oh geez, is it 8:30 already?"

Ended up sleeping from 7:30 to 12:30 (it's 12:48 now) after I got in and ate dinner. >.>

Tropical Cyclone Bulletin #7
TYPHOON KAREN (SANBA)
11:00 AM PhST September 14 2012
==============================

Typhoon "KAREN" has maintained its strength as it continues to traverse the East Philippine sea in a North Northwest direction

At 10:00 AM PhST, Typhoon Karen (Sanba) located at 18.5°N 129.6°E or 740 km east of Aparri, Cagayan has 10 minute sustained winds of 100 knots with gusts of 120 knots. The cyclone is reported as moving north northwest at 8 knots.

Additional Information
===========================

Estimated rainfall amount is from 15-30 mm per hour (heavy to intense) within the 550 km diameter of the typhoon.

Fishing boats and other small seacrafts are advised not to venture out over the eastern seaboard of the country due to strong winds generated by Typhoon "KAREN".

"KAREN" will continue to enhance the Southwest Monsoon that will bring light to moderate rains over Metro Manila and occasional moderate to heavy rains over CALABARZON, MIMAROPA and Western Visayas.

The public and the disaster coordinating councils concerned are advised to take appropriate actions and watch for the next bulletin to be issued at 11 p.m. today.

The remnants of Karen have shown themselves once again! :P

Check out that tropical wave at 11N/41W. That little critter has shown some persistence. I wonder if the NHC will place a yellow circle there in the near term. It has a chance to develop and maybe become a Caribbean cruiser.

The MODIS instrument aboard NASA's Aqua satellite captured this true-color image of Hurricane Ivan on Septebmer 13, 2004 at 19:00 UTC (3:00 PM EDT). At the time this image was taken Ivan was located approximately 110 km (70 miles) south-southeast of the western tip of Cuba and was moving towards the northwest at 13 km/hr (8 mph). Ivan had maximum sustained winds of 260 km/hr (160 mph) with higher gusts. The MODIS Rapid Response System provides this image at additional resolutions and formats.
Date 13 September 2004Hurricane Emily was spinning through the Caribbean south of Jamacia on July 16, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite captured this image at 15:45 UTC (11:45 a.m. Eastern Daylight Time). At this time, Emily was a well-developed hurricane with winds over 230 kilometers an hour (125 knots) and gusts as high as 285 km/hr (155 knots). As shown in this satellite image, the storm is passing roughly east to west well south of Jamaica (around 160 kilometers, or 100 miles), but the heavy rains in the storm�s outer bands fell on an already sodden island still recovering from Hurricane Dennis, which similarly glanced the island on July 7. Emily�s rains caused flooding, which has resulted in four deaths on the island. Tourists in the Yucatan Peninsula are being evacuated from resort areas and beaches as the hurricane continues on track to make landfall there during the morning of July 18, 2005.

Date 23 August 1992The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite captured this true-color image of Hurricane Isabel about 400 miles north of Puerto Rico on September 14, 2003, at 14:45 UTC. At the time, Isabel was packing maximum sustained winds of 155 miles per hour, making it a rare and powerful Category 5 hurricane on the Saffir-Simpson Hurricane scale.
Date 14 September 2003Hurricane Dean on August 20 at approximately 1841 UTC. This image was produced from data from NOAA-18, provided by NOAA.
Date 20 August 2007Hurricane Felix on September 2 at approximately 1810 UTC. This image was produced from data from NOAA-18, provided by NOAA.
Date 2 September 2007Hurricane Wilma was a powerful Category 5 storm when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this image at 12:40 p.m. Eastern Daylight Time, on October 19, 2005. Less than 24 hours before this image was taken, Wilma had rapidly grown into a record-breaking, powerful storm. Winds around the eyewall of the storm were raging at 280 kilometers per hour (175 miles per hour). Just hours before, National Oceanographic and Atmospheric Administration (NOAA) aircraft measured a record-low air pressure of 882 millibars in the center of Hurricane Wilma, making it the most intense hurricane ever observed in the Atlantic basin. Wilma also broke records for the fastest development of a storm, going from tropical storm status to Category 5 hurricane in less than 24 hours. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response Team provides this image at additional resolutions.

That would be a really interesting track and possibly even a threat to the US if that happened.


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.
