February 2012 the globe's 22nd warmest; record Hawaii hailstone confirmed

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.

Global drought text/assessment for the month:
In February 2012, short-term drought conditions expanded significantly in the Northern Hemisphere while remaining nearly the same in the Southern Hemisphere. In North America, the drought intensified in the Canadian Plains and higher-latitudes, as well as through the Upper Midwest of the U.S. In Europe, drought intensified around the Mediterranean Sea but eased in Eastern Europe. Asia saw drought intensify in the East and South, and particularly in west-central Russia. Drought in South America remained nearly the same as last month, concentrated mostly near the equator. Similarly, drought conditions in Africa intensified around the equator. In Australia, drought remains largely again this month. It is estimated that drought was impacting nearly 397 million people at the end of February, over three-times as many people as affected in January.

Population under exceptional drought for the last three months : 397,185,000

Tropical Disturbance Summary
TROPICAL DEPRESSION 17F
9:00 AM FST March 29 2012
=================================

At 21:00 PM UTC, Tropical Depression 17F (1000 hPa) located at 18.4S 175.7E is reported as slow moving southward. Position fair based on multisatellite visible/infrared imagery and peripheral surface observations. Sea surface temperature is around 29C.

Organization has improved slightly past 12 hours. Convection remains persistent to the east of the partially exposed low level circulation center. Tropical depression 17 lies under an upper diffluent region in a low to moderate sheared environment and is expected to move into an area of increasing shear. Cyclonic circulation extends up to 500 HPA.

Most global models have picked up the system and are moving it south with little intensification.

Potential for this system to develop into a tropical cyclone in the next 4-48 hours remains LOW.
