Note: Satellite data is unavailable this month due to processing problems; blended satellite/SSMI products should be available again in the September-November seasonal report.
 Global Temperature
Mean monthly temperature anomalies for the three-month period June through August (using a base period 1880-1998) are shown in the above figure. The combined land and sea surface temperature anomaly for this period was 0.31 deg C, down 0.36 deg C from the record value recorded in 1998. The effects of the shift from El Niño to La Niña conditions are still evident in both land and ocean temperatures. The ocean temperature anomaly, 0.20 deg C, was less than half the 1998 value, 0.54 deg C, while the average land temperature anomaly fell to 0.57 deg C from 0.98 deg C in the year-ago period.
Although global land temperatures have cooled below the record 1998 values, most land areas of the world continue to experience much above average temperatures. The adjacent figure shows the largest positive anomalies in the June through August period occurred in the northern hemisphere across portions of Europe, the Middle East, northern Africa and eastern North America, with temperatures more than 4 deg C above the long term average in many areas. (Grid boxes contain at least 2 out of 3 months of data during the June - August period.)

Temperatures across the U.S. for the June through August period reflected the general circulation pattern which showed a trough in the west (cooler than normal temperatures) and a ridge in the east (warmer than normal temperatures). Warmest anomalies were observed over portions of eastern Canada and across Europe (3-4 deg C in most areas). The only area of widespread below-average temperatures was across portions of northern Scandinavia where anomalies were 2-3 degrees C below normal in most areas.
Global Precipitation

Several areas experienced much above average precipitation in the June-August season. The most notable areas included portions of the Sahel and Korea with flooding reported in these areas. Dryness and drought conditions affected portions of the U.S. and western India. Additional information on these events are available at Drought in the U.S. and the Global Regional Analyses pages.
