Collection and arrangement of the historical records of climatic changes andenvironment evolution, especially in the aspect of calamities, are made on the history documents ofpast 1500 years about Hai'an region, Jiangsu Province. There existed two obvious flooding-droughtfrequently-occurring periods: one was from 1550 AD to 1850 AD and another was 1000 AD to 1200 *** period of 1550 AD to 1850 AD is interrupted by two relatively arid and cold climatic periods:one was from 1630 AD to 1700 AD and another was 1750 AD to 1820 AD. The main characteristic of thecalamity periods is that they occurred by turns, and sometimes, both drought and flooding occurredin the same year. The instability of the climatic changes in the Little Ice Age may be the mainreason of the frequently-occurring flooding and drought in Hai'an region. Research results also showthat the frequently-occurring periods of flooding and drought is in close relationship with thesolar activity, and therefore, occurrence of the flooding and drought may be in relation with theintensity of the solar activity. This hypothesis may need further study in the future.

THE IMPACT OF PRECEDING ATMOSPHERIC CIRCULATION AND SST VARIATION ON FLOOD SEASON RAINFALL IN YUNNAN

引用

Journal of Tropical Meteorology 2005年第2期11卷 121-130页

作者：严华生鲁亚斌程建刚段鹤杨素雨 Department of Atmospheric Sciences / Yunnan University Kunming 650091 China Department of Atmospheric Sciences / Yunnan University Kunming 650091 China Yunnan meteorologicalbureau Kunming 650034 China Yunnan meteorologicalbureau Kunming 650034 China Simao Prefecture Meteorological Bureau Simao 665000 China

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.
