Weekly Global Climate Highlights Map for July 27, 2002

1. Northwestern United States and Southwestern Canada:

MORE ABNORMALLY WARM WEATHER
Temperatures averaged 2°C to 6°C above normal across much of southwestern Canada and northwestern United States, with the mercury soaring above 40°C in parts of interior Washington. Weekly highs were generally in the thirties (°C) except for twenties (°C) along the coasts of British Columbia [WARM - Up to 9 weeks].

2. Central United States:

MOISTURE SHORTAGES CONTINUE
Scattered showers delivered 25 to 100 mm to some locations along the Missouri River, but most of the central Great Plains received fewer than 25 mm. Generally less than 120 mm of rain has accumulated during the last 13 weeks, allowing moisture deficits to range from 50 to 200 mm. See the United States Drought Monitor for more details [DRY - Up to 11 weeks].

3. Eastern United States:

RAINS BRING LIMITED RELIEF
Moderate showers and thundershowers dropped 25 to 100 mm of rain on the east-central United States while little or no rain fell on the Northeast. Although 100 to 300 mm of rain has fallen on the region during the last 13 weeks, moisture shortages of 50 to 160 mm dominated the affected area. See the United States Drought Monitor for more details [DRY - Up to 17 weeks].

4. Southern Chile and Adjacent Parts of Argentina:

PRECIPITATION DEFICITS PERSIST
Little or no precipitation fell on the region, except for 25 to 50 mm in the extreme northern fringes and isolated totals to 100 mm in the Andes. During June and July, southern Chile received 100 to 300 mm of precipitation while totals in adjacent parts of Argentina were less than 100 mm. This resulted in short-term moisture deficits of 75 to 300 mm in Chile and  50 to 150 mm in Argentina [DRY - Up to 7 weeks].

5. Western Russia:

HIGH TEMPERATURES DOMINATE
Weekly temperature departures of +6°C to +9°C prevailed across central European Russia while departures of +2°C to +6°C covered the remainder of European Russia. The mercury soared into the thirties (°C) at most locations during the past week [WARM - Up to 17 weeks].

6. South-Central Siberia:

STILL UNUSUALLY WARM
Temperatures were 2°C to 4°C above normal around Lake Baykal, with highs generally in the thirties (°C) during the past week [WARM - Up to 6 weeks].

7. India:

MOISTURE DEFICITS REPORTED
Although a few coastal locations received more than 100 mm of rain, much of central and northwestern India received fewer than 25 mm of precipitation. Since early June, moisture shortages of 100 to 200 mm accumulated, with larger deficits (to 500 mm) in areas that are normally orographically favored [DRY - 4 weeks].

8. Central China:

DRY ANOMALY DEVELOPS
Little or no rain fell in central China from eastern Qinghai eastward through Shaanxi as unusually dry conditions evolved. During the last 4 weeks, fewer than 60 mm of rain fell, yielding 28-day totals among the lowest 10% of the climatological distribution [DRY - 4 weeks].

9. Southeastern China:

WET WEATHER RETURNS
Heavy rains (100 to 500 mm) drenched eastern Guizhou and northern Guangxi northeastward to Anhui while 50 to 100 mm of rain fell on the remainder of interior southeastern China. Between 100 and 825 mm of precipitation has accumulated, resulting in short-term moisture excesses of 100 to 500 mm [WET - 7 weeks].

10. Eastern Australia:

VERY DRY CONDITIONS SPREAD
For the fifth consecutive week, little or no rain has fallen on the coasts of southeastern Queensland and eastern New South Wales while very little rain has fallen on eastern Victoria during the last 3 weeks. Fewer than 100 mm of rain has accumulated in the region during the past 8 weeks, yielding precipitation shortfalls of 50 to 200 mm [DRY - Up to 7 weeks].
