摘 要: | 根据世界气象组织气温二倍标准差和降水量业务化距平百分率标准,分析了抚顺3站1961—2010年春季(3—5月)、夏季(6—8月)、秋季(9—11月)、冬季(12—2月)和汛期(6—9月)的平均气温、降水量的异常特征。结果表明,抚顺地区易出现气温偏高和降水偏多,冬季是最易出现异常的季节;从年代演变来看,气温和降水异常偏高频数在20世纪90年代以后呈增长趋势,异常偏低频数在20世纪60—70年代呈小幅波动;从区域划分来看,全区春季和夏季易出现气温异常偏高,全区夏季和冬季易出现降水异常偏多,降水异常偏少集中在全区的秋季。

Abstract: | In this study, the anomalies of the average temperature and precipita-tion in spring (March to May), summer (June-August), autumn (September-November), winter (December-February) and flood season (June-September) from 1961 to 2010 were analyzed according to the temperature standard deviation prin-ciple and precipitation abnormity per-centage published by World Meteorolog-ical Organization. The results showed that Fushun was characterized by high temperature and frequent precipitation, and the anomalies mostly occurred in winter. In addition, the frequency of ab-normally high temperatures and frequent precipitations gradually increased from 1990s, and that of abnormally low tem-perature and few precipitation slightly fluctuated from 1960s to 1970s. The ab-normally high temperatures mostly oc-curred in spring and summer, the abnor-mally frequent precipitations in summer and winter while the abnormally few precipitations mostly occurred in autumn in Fushun. |
