NOAA's monthly reports are used by scientists, researchers, and leaders in government, industry and aviation to help track changes in the world's climate. It provides several practical uses as in agricultural advising to farmers, and resource guiding to managers with critical decisions about vital assets such as water or energy. NOAA plays an important role in conserving and managing coastal and marine resources and also predicting and studying the Earth’s environment.
NOAA's National Climatic Data Centerin Asheville, N.C. provides a monthly analysis based on records since 1880 as a part of the suite of climate services. NCDC has released that this october was the sixth warmest on record by combining global land and ocean surface temperature. NCDC scientists have stated however that the average land surface alone was also the sixth warmest and the global ocean surface temperature was the fifth warmest.
Facts:
-The combined global land and ocean surface temperature for October 2009 1.03 degrees F above the 20th century average of 57.1 degrees F.
-The global land surface temperature for October 2009 was 1.48 degrees F above the 20th century average of 48.7 degrees F.
-The worldwide ocean temperature was 0.90 degree F above the 20th century average of 60.6 degrees F. Warmer-than-average temperatures dominated much of the world’s land areas.
-The greatest warm temperature variances during October 2009 were present across Alaska and northern and eastern Russia.
=Cooler-than-average conditions prevailed across Scandinavia, New Zealand, the contiguous U.S., and parts of northern Australia and southern South America.
-According to New Zealand’s National Institute of Water and Atmospheric Research, New Zealand experienced uncharacteristically cool conditions, resulting in the coolest October since 1945. The national average was 51.1 degrees F, 2.5 degrees F below the long-term average.
Average Arctic sea ice coverage was 2.9 million square miles during October. This is 19.2 percent less than the 1979-2000 average and the second smallest October extent, behind 2007, since records began in 1979.
-Antarctic sea ice extent in October was 1.6 percent above the 1979-2000 average, the ninth largest October extent on record.
=Hurricane Rick became the second-most intense Northeast Pacific hurricane on record, behind 1997’s Linda, and the strongest hurricane to form in October since reliable records began. Rick made landfall near Mazatlan, Mexico on October 21st, resulting in two fatalities.
