Global Analysis - Summer 1999


Global Temp Anomalies, Jun-Aug

The global mean temperature for June through August, 1999, was well above the long-term average, based on preliminary data. In fact, for nearly every month in the past 10 years, the global mean land temperature has been above the long-term (1880-1998) mean. Even so, this 3-month global mean temperature was considerably cooler than the record warmth experienced in June through August of 1998, largely due to cooler sea surface temperatures this year. See the Global Analysis and Global Regional Analysis pages for more details on the global climate. Global Monthly Anomalies

For the three-month period June through August, 1999, the mean temperature for the contiguous U.S. was well above the long-term average, based upon preliminary data. The bars in this graph are departures from the 1895-1998 mean. The curved line is a nine-point binomial filter which shows the decadal-scale variations.
Based on preliminary data, average total precipitation for the contiguous U.S. for the period June through August 1999 was well below the long-term average, falling below the long-term average for the first time in 8 years. The bars in this graph are departures from the 1895-1998 mean. The curved line is a nine-point binomial filter which shows the decadal-scale variations. See the U.S. National Analysis and U.S. Regional / Statewide Analyses pages for more details on the U.S. climate. US Precip Anomalies, Jun-Aug

Top of Page Extreme Events

During the June-August 1999 period, several areas of the world experienced extremes in climate. The eastern and southeastern portion of the U.S. experienced drought conditions with warm temperatures and the lack of rainfall in many areas. A full report is available at the Drought in the U.S. page. Globally, extended drought conditions caused problems across portions of western Russia, the Middle East, eastern India, Uganda and Kenya. Flooding has been a particular problem across portions of China and eastern India, Bangladesh, northern Sudan, and parts of southeast Asia.
