| 摘 要： | Spatial and temporal distribution characteristics and scale range of two significant areas were
obtained by analyzing the relationship among summer rainfall in Yunnan province, height field and SST field
(40°S – 40°N, 30 °E – 70°W) across the North Hemisphere at 200 hPa, 500 hPa and 850 hPa for Jan. to May and
correlation, and field wave structure. Remote key regions among summer rainfall in Yunnan province, height
field and SST field (40°S – 40°N, 30°E – 70°W) across the North Hemisphere at 200 hPa, 500 hPa and 850 hPa
were studied through further analyzing of the circulation system and its climate / weather significance. The result
shows that the forecast has dependable physical basis when height and SST fields were viewed as predictors and
physical models of impacts on rainy season precipitation in Yunnan are preliminarily concluded. |
