 European/Asian Snow Cover Anomaly
European/Asian Snow Cover Anomaly

The featured product above is the European/Asia snow cover anomaly. In this month's analysis, two large anomalies were evident. A large area of negative anomalies, denoting below average snow, covered much of Central Europe from the Ukraine, north of the Black Sea into Scandinavia. The below average snow cover in the Baltic regions is due to warmer than usual temperatures; precipitation fell as rain rather than snow. The region around the Black Sea was also warmer than average, with little precipitation and below average snow cover. In contrast, snow cover was above average across much of southern Siberia, Mongolia and parts of western and northern China. These areas were also quite cold during the month. The combination of above average snow cover and cold temperatures killed almost 16,000 head of livestock, and thousands of families are migrating to save herds from another devastating winter, according to the Mongolian State Emergency Commission. See the NOAA Daily Eurasia Daily Snow/Ice Cover Movie Loop for November 2000. Additional details and global regional information are available in other sections of this report.

Top of Page South American Wetness Product

The largest positive wetness anomalies this month were observed over northeastern Argentina. The area from central Cordoba into the southern Chaco has been wet the past two months with parts of the region receiving over 650 mm of precipitation. Media reports indicate losses of approximately 25 million dollars to the agriculture and cattle raising industry in this region. The flooded zone reportedly extends over 6 districts, where agricultural and cattle production represents 25% of the country's total. Positive wetness anomalies were also noted across the Amazon river basin where the rivers are shown. Negative anomalies were noted across the higher mountainous regions of southern Peru and Bolivia. These areas had above average snow cover, hence less precipitation in the form of rain. This shows up as a negative wetness anomaly. South American Wetness Product

Top of Page Southeast Asia Wetness Product

The continent is a study in contrasts this month. Positive wetness anomalies were evident across Bangladesh southeastward into Thailand, Cambodia and Vietnam. Although Indochina has entered a drier period, flooded ground along the Mekong river is still evident in Cambodia and Vietnam as a positive wetness anomaly signal. This was caused by the leftover flooding from the devastating July-October southwest monsoon in this region, rather than any abnormally heavy rains during November.

In contrast, parts of the Korean peninsula and adjacent areas in China were dry with scattered areas of drought. Drier than average conditions were noted across much of India and Pakistan. Most of India and east Pakistan are now entering their dry season.

Top of Page African/Middle East Temperature Product

Cool anomalies this month were noted across both the northwestern and southeastern sections of the African continent. In the northwest, a series of storms off the Atlantic brought periodic cloudiness and cooler than average temperatures. In southeast Africa, a persistent flow of moisture and cloudiness across the region, from Zimbabwe southward into eastern South Africa, kept the region cooler than average. Rainfall was also higher than average across a portion of Zimbabwe and Mozambique which had the coolest temperature anomalies
Positive temperature anomalies were observed for the second month is a row across parts of Angola and Namibia. Other areas with scattered positive temperature anomalies were noted across parts of central Africa at about 5 degrees north, into southern Saudi Arabia and parts of the Middle East.

Much of the United States was cool during the month. The largest cold anomalies were observed over portions of the western states. Some areas in the central Rockies reported anomalies greater than 4 C below average. Temperatures were also below average across eastern portions of the U.S. but the anomalies were not as large as in western areas. Positive temperature anomalies were found across New England, and across much of Canada.

A ridge of high pressure aloft over central Europe brought dry and warm conditions from Germany eastward into the Ukraine, Belarus and extreme western Russia. Portions of the region were more than 4C above average. Areas along the Atlantic coast of Europe and across Scandinavia had showers, cloudiness, and negative temperature anomalies.

East of this region, across central Siberia eastward into northern China, cold weather was persistent during the month. The temperature at Tura, Russia in central Siberia reached -52 C during the latter half of the month.

Top of Page Australian Temperature Product

Australia was a study in contrasts this month with cooler than average temperatures across the northern parts of the continent and warm temperatures across the south and southeast sections. The coolest anomalies were noted across the Great Dividing Range in east central Queensland at about -3C. The warmest anomalies of 4 C were in southern South Australia, Victoria and New South Wales. An early season heat wave brought temperatures above 40 C in parts of northwestern New South Wales and South Australia during the month.
