基于云模型的四川盆地气候变化时空分布特征分析
Analysis on Characteristics of Temporal-spatial Climate Distribution in Sichuan Basin Based on Cloud Model
摘要
Abstract
In order to study the temporal and spatial distribution characteristics of climate change in Sichuan Basin,based on the monthly precipitation and monthly air temperature data of 15 meteorological stations in the Sichuan Basin from 1955 to 2010,monthly evaporation was calculated using the Takahashi Koichiro evaporation equation.The cloud model is used to describe the distribution of precipitation,temperature and evaporation in time.The spatial and temporal distribution characteristics of precipitation,air temperature and evaporation were analyzed by Kendall rank correlation method.The results show that the distribution of precipitation is the most uneven in the annual and seasonal precipitation series from 1955 to 2010,followed by in autumn.In the annual and quarterly temperature series,the winter temperature distribution is the most uneven and the most unstable,but the autumn temperature distribution is the most stable.In the annual and quarter evaporation series,the distribution of evaporation in winter is the most uneven,and the annual evaporation is most evenly distributed.The annual and quarterly precipitation has been declining.In the annual and seasonal temperature,except the summer temperature,the others are on the ascending trend.The annual and autumn evapotranspiration showed a decreasing trend,and the evaporation in spring,summer and winter showed an increasing trend.The analysis of the spatial and temporal distribution of climate change in Sichuan Basin can provide scientific reference and technical support for climate change research in this region.关键词
