| Abstract: | Based on the seasonal mean temperature (T, winter), wind (V, winter) andprecipitation (R, summer) observed at Huimin, Binzhou and Kenli meteorologicalstations from 1957 to 1996, the characteristics of climate over the Yellow Riverdelta region in recent 40 years are investigated. The analysis reveals that: (1) thelong-term climate change tendency of T in winter is that it becomes warmer andV becomes weaker and R in summer changes little; (2) there are turnings andclimate jumps of T in winter, V in spring and R in summer. The jump years were1986 (T) and 1975 (V) and the turning years were 1972 (T), 1978 and 1989 (R);and (3) the variation periods were 3.6-4.5 years for T in winter, V in springand R in summer, and what is more, the periods of 18 and 6 years also existedfor V and R respectively. |
