摘要
应用1957～2001年广西76站逐月降水量和平均气温资料,通过计算各站降水和气温的趋势系数,分析广西45a来年、季、月降水和气温长期变化的特征。结果表明,广西的年降水量没有明显的长期变化异常,但季、月的降水量表现出不同的长期变化特征;广西的年平均气温有很明显的增温趋势,变暖主要是发生在夏、秋季,而春季气温则有比较明显的下降趋势。
Analyze the long-term changing tendency and distribution of yearly, seasonal and monthly precipitation and air temperature of Guangxi in the past 45 years by using information in the 76 observatory stations on monthly precipitation and average air temperature during 1957 ~ 2001, and calculating the tendency coefficient of precipitation and air temperature in these stations. The results show that there is no significant long-term change abnormality in yearly precipitation, yet a different long-term changing characteristics on seasonal and monthly precipitation; there is an obvious increase in yearly average air temperature and temperature increase happens mainly in summer and autumn, while there is a significant decrease in spring temperature. Meantime the long-term change of precipitation and temperature is featured with obvious regional characteristics.
