The extremely warm temperatures in Scandinavia and Eastern Europe were the dominant climatological feature in June. These anomalies were associated with a persistent upper level ridge that covered the region for almost the entire month. Also evident were the cold sea surface temperature anomalies which have persisted in the east equatorial Pacific for almost a year. These anomalies are associated with La Niña conditions that continue to prevail over the tropics.
| Global land precipitation averaged 2.8 mm below the 1900 to 1998 long term mean in June. See the Global Analysis and Global Regional Analyses pages for more details on the global climate.

Based upon preliminary data, June 1999 temperatures ranked near the long term mean for the contiguous U.S. 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, June 1999 precipitation averaged across the contiguous U.S. ranked near the long term mean, despite intensifying drought conditions in the northeast. 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.

Extreme Events
Several areas of the world, including a good deal of the Middle East as well as northern and western Mexico, are experiencing drought. In some areas of Mexico, the drought is entering its fifth year with one-third of the country being affected. Drought problems are also plaguing portions of the southeastern U.S. In contrast, flooding is a problem in parts of northwest China's interior Qinghai province. A full report on selected global extremes is available under the Climate-Watch, June 1999 page.
