Moscow hits 102°F; hottest day ever in Finland; 90L a long-range theat
At 4pm local time today in Moscow, Russia, the temperature surpassed 100°F for the first time in recorded history. The high temperature of 100.8°F (37.8°C) recorded at the Moscow Observatory, the official weather location for Moscow, beat Moscow's previous record of 99.5°F (37.5°C), set just three days ago, on July 26. Prior to 2010, Moscow's hottest temperature of all-time was 36.6°C (98.2°F), set in August, 1920. Records in Moscow go back to 1879. Baltschug, another official downtown Moscow weather site, hit an astonishing 102.2°F (39.0°C) today. Finland also recorded its hottest temperature in its history today, when the mercury hit 99°F (37.2°C) at Joensuu. The old (undisputed) record was 95°F (35°C) at Jvaskyla on July 9, 1914. There is little relief in sight, as the latest forecast for Moscow predicts continued highs in the 90s for most of the coming week.
A remarkable year for extreme heat
Finland's new national heat record makes it the fourteenth country (or semi-independent territory) to break an all-time hottest temperature record this year. My source for extreme temperature records is Chris Burt, author of the book Extreme Weather. July in Moscow is easily going to smash the record for hottest month in Moscow's history. By my rough estimate, the temperature has been 18°F (10°C) above average this month. The record hottest July, in 1938, had temperatures 5.3°C above average. Given that the planet as a whole has seen record high temperatures the past four months in a row, it should not be a surprise to see unprecedented heat waves like the Russian heat wave. A record warm planet "loads the dice" in favor of regional heat waves more extreme than anything experienced in recorded history.
Figure 1. Russia's heat wave has contributed to a severe fire season this July. Fires on dry peat bogs east of Moscow are covering the city with smoke as this photo taken yesterday (July 28, 2010.) Tiny red dots indicate hot spots of high surface temperatures associated with fires, and multiple clusters of such dots appear east of Moscow. Dull gray smoke mixes with opaque white clouds east and northeast of the capital city. Air pollution levels in Moscow due to the smoke and smog are so high that residents have been warned to stay home rather than go in to work. Firefighters are battling 340 blazes across Russia covering 86,658 hectares (214,136 acres) amid a drought that led the government to declare weather-related emergencies in 23 crop-producing regions. Agriculture Minister Yelena Skrynnik said on July 23 that the drought had damaged 10.1 million hectares, or 32 percent of all land under cultivation, according to Bloomberg. Raging fires have destroyed hundreds of houses across Russia today and forced mass evacuations in the city of Voronezh, 300 miles southeast of Moscow, according to the Associated Press.

Fourteen extreme national high temperature records have been set in 2010
This year now ranks in second place for the most number of countries that have set extreme heat records, according to a list supplied to me today by Chris Burt. The new list removes a number of old disputed records, resulting in the year 2007 surpassing 2010 as the year with the most extreme heat records--fifteen. Keep in mind that the matter of determining extreme records is very difficult, and it is often a judgment call as to whether an old record is reliable or not. The list of countries (225) includes islands that are not independent countries, such as Puerto Rico and Greenland. One-third (33%) of those heat records were set in the past ten years. Ten years have had extreme heat records set at five or more countries on Mr. Burt's list:
2007: 15 records
2010: 14 records
2003: 12 records
2005: 11 records
1998: 9 records
1983: 9 records
2009: 6 records
2000: 5 records
1999: 5 records
1987: 5 records
I highly recommend the book Extreme Weather by Chris Burt for those interested in weather records. I thank Mr. Burt and weather record researchers Maximiliano Herrera and Howard Rainford for their assistance identifying this year's new extreme temperature records. Here's a list of the fourteen nations that have set extreme heat records this year:
Finland recorded its hottest temperature on July 29, 2010, when the mercury hit 99°F (37.2°C) at Joensuu. The old (undisputed) record was 95°F (35°C) at Jvaskyla on July 9, 1914.
Qatar had its hottest temperature in history on July 14, 2010, when the mercury hit 50.4°C (122.7°F) at Doha Airport.
Russia had its hottest temperature in history on July 11, when the mercury rose to 44.0°C (111.2°F) in Yashkul, Kalmykia Republic, in the European portion of Russia near the Kazakhstan border. The previous hottest temperature in Russia (not including the former Soviet republics) was the 43.8°C (110.8°F) reading measured at Alexander Gaj, Kalmykia Republic, on August 6, 1940. The remarkable heat in Russia this year has not been limited just to the European portion of the country--the Asian portion of Russia also recorded its hottest temperature in history this year, a 42.3°C (108.1°F) reading at Belogorsk, near the Amur River border with China. The previous record for the Asian portion of Russia was 41.7°C (107.1°F) at nearby Aksha on July 21, 2004.
Sudan recorded its hottest temperature in its history on June 25 when the mercury rose to 49.6°C (121.3°F) at Dongola. The previous record was 49.5°C (121.1°F) set in July 1987 in Aba Hamed.
Niger tied its record for hottest day in history on June 22, 2010, when the temperature reached 47.1°C (116.8°F) at Bilma. That record stood for just one day, as Bilma broke the record again on June 23, when the mercury topped out at 48.2°C (118.8°F). The previous record was 47.1°C on May 24, 1998, also at Bilma.
Saudi Arabia had its hottest temperature ever on June 22, 2010, with a reading of 52.0°C (125.6°F) in Jeddah, the second largest city in Saudi Arabia. The previous record was 51.7°C (125.1°F), at Abqaiq, date unknown. The record heat was accompanied by a sandstorm, which caused eight power plants to go offline, resulting in blackouts to several Saudi cities.
Chad had its hottest day in history on June 22, 2010, when the temperature reached 47.6°C (117.7°F) at Faya. The previous record was 47.4°C (117.3°F) at Faya on June 3 and June 9, 1961.
Kuwait recorded its hottest temperature in history on June 15 in Abdaly, according to the Kuwait Met office. The mercury hit 52.6°C (126.7°F). Kuwait's previous all-time hottest temperature was 51.9°C (125.4°F), on July 27,2007, at Abdaly. Temperatures reached 51°C (123.8°F) in the capital of Kuwait City on June 15, 2010.
Iraq had its hottest day in history on June 14, 2010, when the mercury hit 52.0°C (125.6°F) in Basra. Iraq's previous record was 51.7°C (125.1°F) set August 8, 1937, in Ash Shu'aybah.
Pakistan had its hottest temperature in history on May 26, when the mercury hit an astonishing 53.5°C (128.3°F) at the town of MohenjuDaro, according to the Pakistani Meteorological Department. While this temperature reading must be reviewed by the World Meteorological Organization (WMO) for authenticity, not only is the 128.3°F reading the hottest temperature ever recorded in Pakistan, it is the hottest reliably measured temperature ever recorded on the continent of Asia.
Myanmar (Burma) had its hottest temperature in its recorded history on May 12, when the mercury hit 47°C (116.6°F) in Myinmu, according to the Myanmar Department of Meteorology and Hydrology. Myanmar's previous hottest temperature was 45.8°C (114.4°F) at Minbu, Magwe division on May 9, 1998. According to Chris Burt, author of the authoritative weather records book Extreme Weather, the 47°C measured this year is the hottest temperature in Southeast Asia history.
Ascention Island (St. Helena, a U.K. Territory) had its hottest temperature in history on March 25, 2010, when the mercury hit 34.9°C (94.8°C) at Georgetown. The previous record was 34.0°C (93.2°F) at Georgetown in April 2003, exact day unknown.
The Solomon Islands had their hottest temperature in history on February 1, 2010, when the mercury hit 36.1°C (97°F) at Lata Nendo (Ndeni). The previous record for Solomon Islands was 35.6°C (96.0°F) at Honaiara, date unknown.
Columbia had its hottest temperature in history on January 24, 2010, when Puerto Salgar hit 42.3°C (108°F). The previous record was 42.0°C (107.6°F) at El Salto in March 1988 (exact day unknown).
90L forms in far eastern Atlantic
NHC has designated an area of thunderstorms in the tropical Atlantic as Invest 90L (8.5 N, 30.0 W). Microwave remote sensing suggests there are some decent thunderstorms in 90L, as peak rain rates were around 1 - 2 inches per hour. According to CIMMS wind-shear analyses, 90L is under a moderate 10 - 15 knots of wind shear, and upper level winds over the disturbance are diverging, which creates a vacuum effect that will enhance updrafts and thunderstorm growth. The disturbance is tracking into a broad area of weak shear to the west and northwest. The steering currents for 90L are to the west-northwest, which will move it into this area of weaker shear. The disturbance is at 8°N latitude, which is too close to the Equator to leverage the Earth's spin very well to spin up. As 90L's west-northwest motion carries it farther from the Equator, the additional spin the disturbance gains from the Earth's rotation will aid development, particularly once 90L gets north of 10°N latitude.The Saharan Air Layer with its dust and dry air lurks just to the north of 90L, but the SHIPS model predicts 90L will remain far enough from the dry air over the next five days so that it will not interfere with development.

Model Forecasts and Climatology
The latest 2pm EDT (18Z) runs of the GFDL and HWRF models show 90L developing into a hurricane 3 - 5 days from now. These models suggest that 90L will pass well northeast of the Lesser Antilles Islands. The 18Z GFS model develops 90L into a tropical storm about 7 days from now, and forecasts a track through the northern Lesser Antilles Islands 7 - 8 days from now. The 18Z NOGAPS and 12Z ECMWF models show little development of 90L. The GFDL and HWRF models are too aggressive developing 90L, and likely show too much of a northward motion due to excessive depth of the system they portray. The GFS solution, showing a more delayed development and possible threat to the Lesser Antilles Islands is probably more reasonable. Looking at climatology based on research done by Dr. Bob Hart at Florida State University,, 90L has a 36% chance of developing into a tropical cyclone by 2pm Saturday. NHC is putting these odds at 20%. Dr. Hart also has an experimental product showing that historically, about 30% of all tropical cyclones at 90L's current position eventually hit land as a hurricane. Of course, 90L is not yet a tropical cyclone, but these odds suggest that 90L has the potential to become a dangerous Cape Verdes-type hurricane that will affect land.
Next update
I'll have an update by 8pm Friday.

Rob Carver on the right, Dr. Masters down the middle, Bastardi on the left, hummmm.
Yes El Niño brought on some extra heat. It wasn't near as extreme an El Niño of '97-'98 yet it is well warmer atleast so far, than 1998, even with the deeper solar minimum this last year.
Indeed. You may have to go shopping for that coffee soon.
I will not post the video, just do a search on YouTube for Agenda 21 and you will see for yourself the facts. Just sayin, keep an eye on these folks that push what you are unsure of!!!!
http://www.un.org/esa/dsd/agenda21/res_agenda21_00.shtml
That's right! If you read it, you should be scared of these people or sites, telling you what to do!

;-) Something to watch, J.L lol
Jay Lopez
i am happy too re port that you been re ported
Ha! But I was thinking more recently. XD
I obviously didn't exist back then. LOL!
It's called separation of church and state. They shouldn't be reaching out to any religious group.
Where exactly is this year warmer than 1998?
lol
i 2nd that
whats go party in the snow
Forget? no way, 1st week of November, pfhhhh. Playoffs round the corner.
That's due to their inclusion of false data in the Arctic!
[quote]
the 12-month running mean global temperature in the GISS analysis has reached a new record in 2010…. GISS analysis yields 2005 as the warmest calendar year, while
the HadCRUT analysis has 1998 as the warmest year. The main factor is our inclusion of estimated temperature change for the Arctic region.

And here I thought I was the only crazy one still up. Nice dichotomy between forecasts. It will be interesting to see who ends up being the closest.
I'm still trying to find out EXACTLY where you got the info on Watt's past. You seem to post the source on everything you post, except that.
And on the other side, there is such a thing as posting under a nom-de-plume.
Do you post here under your real name? How can we believe you if you don't?
If all the people who supported AGW posted under their real name, we wouldn't have to guess who Tamino (Open Mind) was, and what HIS credentials were.
Surface obs, surface obs, surface obs. Where the heck did all the red paint in the arctic come from? GISS has 2 stations up there.
Why choose this junk over satellites that have full global coverage? No gaps in the spatial field.
ASCAT missed 90L
darn darn darn
Well thats nothing new, ASCAT is guaranteed to miss when we most need it LOL! -.-
They just interpolate warmth into all the areas where they have no surface stations. What?
IT'S A TRAP!
Why, thank you!
can anyone post any model runs for the new invest(90l)? thanks in advance:)
They used the name Omar in 2008.
...hundreds of climatologists and meteorlogists in NASA, GISS, and NOAA are criminals...
Really Storm? You actually believe that?
And satellite measurement without interpolation into areas with no people standing with thermometers isn't valid?
Why settle for less than full coverage? Those are some BIG gaps! Statistical interpolations are not good enough......why choose that over complete global coverage via satellite? Why on earth would we choose the incomplete dataset over the complete one?
