Weekly Global Climate Highlights Map for January 4, 2003




1. Eastern Canada:

ABOVE-NORMAL TEMPERATURES DOMINATE

Large positive weekly temperature departures (+6°C to +10°C) dominated Canada, with locally higher departures reaching +22°C. The mercury climbed above -10°C across the southern half of the region, but lows plummeted to -20°C throughout northeastern and east-central Canada [WARM - Up to 14 weeks].

 

2. Western United States:

PACIFIC STORM TRACK SHIFTS NORTHWARD

Moderate to heavy precipitation (50 to 200 mm) soaked the region. During the last 4 weeks, the 200 to 500 mm of precipitation was among the highest 10% of the climatological distribution, but provided additional water for use later in the year [WET - 6 weeks].

 

3. North-Central United States:

PRECIPITATION DEFICITS PERSIST

Little or no precipitation fell on the region, except for 10 to 25 mm along the extreme southern fringes. Generally less than 150 mm of precipitation accumulated during the last 13 weeks, resulting in moisture deficits of 50 to 150 mm [DRY - Up to 12 weeks].

 

4. Eastern United States:

MORE WET WEATHER

Between 10 and 100 mm of precipitation fell on the mid-Atlantic, with locally higher amounts approaching 200 mm. The 150 to 250 mm of precipitation during the last 4 weeks was among the highest 10% of the climatological distribution, and essentially eliminated most long-term deficits that plagued the region last year [WET - 4 weeks].

 

5. Northern and Central South America:

WARM ANOMALY REMAINS INTACT

Temperatures averaged 2°C to 5°C above normal across northern and central South America, with highs reaching 43°C in Paraguay, and climbing above 30°C elsewhere. The mercury remained above 20°C throughout the region [WARM - Up to 8 weeks].

 

6. Southwestern Europe and Northwestern Africa:

UNUSUALLY WARM WEATHER DEVELOPS

Temperatures were 3°C to 9°C above normal in Europe while weekly departures ranged from 2°C to 7°C in northwestern Africa. Highs in the twenties (°C) covered Africa and eastern Spain, and ranged from 1°C to 19°C elsewhere. Subfreezing lows were restricted to a few high elevations [WARM - Up to 3 weeks].

 

7. Northern Scandinavia and Northern European Russia:

STILL VERY DRY

Little or no precipitation fell on the region, except for 10 to 25 mm in Estonia. Fewer than 100 mm of precipitation was reported during the last 2 months, with shortfalls of 50 to 150 mm; but, 8-week deficits approached 400 mm in exposed portions of Norway [DRY - Up to 9 weeks].

 

8. Europe and Asia:

BITTERLY COLD AIR COVERS MUCH OF TWO CONTINENTS

Temperatures averaged 3°C to 10°C below normal across most of Europe and Asia, with weekly temperature departures of -10°C to -22°C in northeastern Scandinavia and northwestern Russia. Lows ranged from -20°C to -45°C across most of the region, except for subfreezing lows along the western fringes from Poland and Germany southward to northern Pakistan. The mercury failed to reach the freezing mark in Kazakhstan, northern China, and Russia [COLD - Up to 14 weeks].

 

9. Kenya and Tanzania:

MORE ABUNDANT RAINS

Moderate showers delivered 25 to 50 mm of rain to Kenya and northern Tanzania, with locally heavier amounts (up to 200 mm) in central Tanzania. Precipitation totals of 100 to 320 mm during the last 4 weeks were among the highest 10% of the climatological distribution [WET - Up to 6 weeks].

 

10. Southeastern Africa:

DRY WEATHER RETURNS

Scattered showers dropped 10 to 50 mm of rain on some areas, but much of southeastern Africa received little or no rain. Generally less than 200 mm of rain accumulated during the last 8 weeks, allowing moisture shortfalls to range from 50 to 325 mm [DRY - Up to 10 weeks].

 

11. China and Japan:

MOISTURE SURPLUSES CONTINUE

Between 25 and 100 mm of precipitation (with locally higher amounts to 200 mm) fell on Japan, but most of China received less than 50 mm. China and Japan reported 8-week precipitation totals of 100 to 500 mm, allowing short-term moisture excesses of 50 to 200 mm to accumulate [WET - Up to 8 weeks].

 

12. North-Central Australia:

MOISTURE DEFICITS REMAIN

Moderate to heavy rains (50 to 200 mm) fell on the immediate northern coasts, but inland weekly precipitation totals dropped off rapidly to zero. Much of eastern Australia (not depicted) reported long-term moisture deficits, but 4-week precipitation totals did not fall in the lowest 10% of the climatological distribution. Fewer than 100 mm of rain accumulated across interior portions of northern and central Australia during the last 3 months, yielding 13-week moisture deficits of 60 to 160 mm. Some coastal locations received more than 200 mm during the same period, but shortages approached 275 mm [DRY - Up to 15 weeks].
