Weekly Global Climate Highlights Map for February 22, 2003




1. Great Lakes Region:

STILL VERY DRY

Between 10 and 50 mm of precipitation brought some relief to southern Illinois, the southeastern half of Indiana, and much of Ohio. To the north and west, however, little or no precipitation was reported. Generally less than 150 mm of precipitation has accumulated during the last 91 days, yielding precipitation shortfalls of 50 to 250 mm [DRY - Up to 19 weeks].

 

2. Eastern United States:

COLD CONDITIONS DOMINATE

Temperatures averaged 2°C to 5°C below normal across the mid-Atlantic and southern New England during the past week. Although highs were generally above freezing during the week, the mercury plummeted below -10°C at most locations [COLD - Up to 3 weeks].

 

3. Northern South America:

WARM AIR RETREATS NORTHWARD

Weekly departures of +2°C to +4°C prevailed across northern South America, with isolated higher departures approaching +5°C. Highs were generally in the thirties (°C) and lows were in the twenties (°C) [WARM - Up to 7 weeks].

 

4. Central South America:

SHARP TEMPERATURE REVERSAL REPORTED

Temperatures averaging 2°C to 7°C below normal brought an abrupt end to the warm weather across Paraguay and northern Argentina. Weekly lows ranged from 5°C to 15°C, but highs were generally in the thirties (°C) [COLD - 2 weeks].

 

5. Southern Europe:

UNUSUALLY COLD WEATHER PERSISTS

Unusually cold conditions, characterized by weekly departures of -2°C to -8°C, dominated the southern half of Europe during the past week. Subfreezing lows dominated the region, and the mercury failed to reach 20°C throughout the region [COLD - Up to 4 weeks].

 

6. South Africa:

TEMPERATURES MODERATE

Temperatures were generally within 3°C of normal, except in extreme northern South Africa, where weekly departures reached +5°C. Highs were generally in the thirties (°C) [WARM - Up to 7 weeks].

 

7. Zimbabwe and Mozambique:

RAINFALL DEFICITS CONTINUE

Fewer than 25 mm of rain were reported at a limited number of locations, but reliable precipitation data are lacking in most of the region. During the last 13 weeks, moisture shortages ranged from 50 to 350 mm at the few available reporting stations [DRY - Up to 17 weeks].

 

8. China and Southeastern Asia:

WARM ANOMALY DEVELOPS

Temperatures averaged 2°C to 9°C above normal across the region, with the largest positive departures occurring across the western interior of China. Highs exceeded 30°C across the Indochinese Peninsula and in western China as far north as 30°N. The mercury remained above freezing as far north as 33°N [WARM - Up to 3 weeks].

 

9 Eastern Australia:

MODERATE TO HEAVY RAINS BRING SOME RELIEF

Between 50 and 200 mm of rain fell on eastern New South Wales and extreme southeastern Queensland while 25 to 100 mm were recorded in the western portions of New South Wales and Victoria. The remainder of eastern Australia received fewer than 25 mm of rain. Despite the abundant precipitation last week, 13-week totals were generally below 350 mm along the coast and less than 100 mm inland, allowing moisture deficits to remain in the 50 to 300 mm range, with locally larger deficits reaching 500 mm [DRY - Up to 22 weeks].
