Weekly Global Climate Highlights Map for March 8, 2003




1. North America:

COLD AIR REMAINS ENTRENCHED

Bitterly cold air, with temperatures averaging 6°C to 18°C below normal, dominated much of Canada and the north-central United States while weekly departures of -2°C to -6°C covered the remainder of the region. Lows of -20°C penetrated as far south as 42°C while subfreezing lows reached northern Texas and southern Arkansas. The mercury failed to reach 20°C north of 40°N, and remained below freezing across Canada and the north-central United States [COLD - Up to 5 weeks].

 

2. Midwestern United States:

MORE VERY DRY WEATHER

Little or no precipitation was reported across most of the Midwest; however, between 10 and 25 mm of precipitation fell on the southern and eastern fringes of the region. Generally less than 100 mm of precipitation has accumulated during the last 13 weeks, resulting in shortfalls of 50 to 235 mm [DRY - Up to 21 weeks].

 

3. Caribbean Basin:

ABNORMALLY WARM CONDITIONS DEVELOP

Temperatures averaged 2°C to 5°C above normal in Florida while weekly departures of +2°C to +3°C prevailed elsewhere. Highs were generally in the thirties (°C) [WARM - Up to 3 weeks].

 

4. South America:

WARM WEATHER RETURNS

Weekly temperature departures of +2°C to +3°C dominated South America, with temperatures averaging 3°C to 6°C above normal prevailing across Argentina. Highs were generally in the thirties (°C). The mercury remained above 20°C across the continent except for Chile and Argentina [WARM - Up to 9 weeks].

 

5. Central South America:

VERY WET CONDITIONS REPORTED

Moderate to heavy rains (25 to 200 mm) were observed across much of central South America as wetness returned after a break of about 2 or 3 months. During the past 8 weeks, 100 to 500 mm of precipitation accumulated, yielding short-term moisture surpluses of 50 to 325 mm [WET - Up to 7 weeks].

 

6. Iceland and Southern Greenland:

MILD WEATHER SHIFTS WESTWARD

Temperature departures ranged from +2°C along the coasts of Iceland to +17°C in the deep interior of Greenland. The mercury climbed above the freezing mark throughout the region while lows of -10°C or lower were restricted to areas above 65°N [WARM - Up to 4 weeks].

 

7. Europe:

DRY ANOMALY EXPANDS

Little or no precipitation fell on much of Europe, except for light to moderate amounts (10 to 50 mm) on the higher elevations of the Alps. Precipitation totals were generally less than 50 mm and were among the lowest 10% of the climatological distribution [DRY - Up to 6 weeks].

 

8. Southeastern Europe and Southwestern Asia:

COLD ANOMALY SPREADS EASTWARD

Temperatures were 2°C to 10°C below normal, with subfreezing lows across the entire region. The mercury plummeted below -20°C across most of Kazahkstan [COLD - Up to 6 weeks].

 

9. Western Sahel:

HIGH TEMPERATURES PERSIST

Weekly high temperatures of 35°C to 42°C dominated the region, with weekly temperatures departures ranging from +2°C to +4°C at most locations [WARM - Up to 5 weeks].

 

10. Southern Africa:

WARM ANOMALY CONTINUES

Weekly departures of +2°C to +5°C prevailed across most of southern Africa, with highs ranging from 25°C to 39°C [WARM - Up to 9 weeks].

 

11. South Africa:

STILL VERY DRY

Little or no rain fell on east-central and southeastern South Africa. Between 100 and 300 mm of rain fell on the region during the past 13 weeks, resulting in moisture shortages of 70 to 240 mm [DRY - Up to 19 weeks].

 

12. Zimbabwe and Mozambique:

REMAINS OF TROPICAL STORM JAPHET DELIVER HEAVY RAINS

Torrential rains (100 to 500 mm) drenched eastern Zimbabwe and central Mozambique as the remnants of Tropical Cyclone Japhet trekked across the region [Episodic Event].

 

13. China and Japan:

WET ANOMALY DEVELOPS

Between 25 and 100 mm of precipitation fell on Anhui, Jiangxi, Fujian, Zhejiang, and Shanghai provinces of eastern China and on most of southern and central Japan. Locally heavier rains, in excess of 100 mm, drenched parts of the southern and eastern coasts of Japan. Precipitation totals of 100 to 300 mm during the last 4 weeks were among the highest 10% of the climatological distribution [WET - Up to 6 weeks].

 

14. Southeastern Asia:

VERY WARM WEATHER PERSISTS

Temperatures averaged 2°C to 5°C above normal across much of the Indochinese Peninsula, with highs generally in the thirties (°C) [WARM - Up to 5 weeks].
