广西气温、降水异常的统计特征

Statistical Features of Temperature and Precipitation Anomalies in Guangxi

利用世界气象组织划分气候异常的标准， 统计了广西８６站１９６１—１９９８年的气温和降水资料， 得出了广西近４０ａ气温、降水异常的时空分布特征， 发现异常的出现以局部性较多， 全区性较少， ９０ 年代的４ 月、７ 月、９月、１０月月平均气温异常较频繁， 月降水量异常较多的是１ 月、３月、６ 月、７

WT5,5”BZ]The WMO's standard of anomalous climate is used in analysis of the temperature and precipitation data at 86 stations in Guangxi from 1961 to 1998.The analysis reveals that number of local anomalous climate are greater than that of extensive anomlous climate over the whole Guangxi. Monthly mean temperatures in the 1990s are frequently anomalous in April,July,September,and October while monthly mean precipitation is frequently anomalous in January,March,June,and July.
