Summer precipitation is enhanced throughout the U.S. due to SST anomalies. The increase in precipitation is caused by enhanced low-level moisture flux, strong upper-level cyclonic circulation and intensified zonal wind over the U.S. The second part was to assess U.S. precipitation variability in the model, forced by the observed time-varying SST (1950-1994). In both winter and summer, the response of U.S. precipitation to tropical SST is significant and similar to observations. The response to North Pacific SST is weak in winter. In summer, the North Pacific SST has few effects on U.S. precipitation, but has significant impacts on 500 mb height. The model results confirm the variability of U.S. precipitation associated with the tropical Pacific SST in both seasons and suggest some effects of North Pacific SST on the atmospheric circulation.","abstract_html":"The first part of the modeling study was to simulate summertime U.S. precipitation in response to prescribed North Pacific SST anomalies, related to Great Plains precipitation.
