“蒸发悖论”现象在吉林省地区的表现
“Evaporation Paradox” phenomenon expression in Jilin Province
摘要
Abstract
Using the meteorological information during 1963 to 2012 of 45 weather stations in Jilin Province ,ana-lyzed the changing trend of pan evaporations in 50 years ,which observation data were collected from the 20 cm caliber e-vaporation pan .Combined the climate change ,emphatically analyzed the spatial and temporal distribution rule of the“E-vaporation Paradox”in Jilin Province .The results showed that:In 50 years ,the pan evaporation has assumed a signifi-cant decline tendency in Jilin Province .Among them ,in spring the decline rate and decrease range was the maximum , and in other three seasons despite the change trend was slightly rose ,but was not remarkable .In the past 50 years ,on the whole the“paradox evaporate”was existed in Jilin Province .In geography ,the number of weather station existed“e-vaporation paradox”phenomenon was presented the distribution form as gradually increasing from west to east .But the paradox rarely appeared in Changbai Mountain areas .In different years ,the number of stations existed paradox was dif-ferent in Jilin Province ,in 1980s was the maxima ,followed was 2000s and 1970s ,the minimum was 1990s .From the seasons ,the“evaporation paradox”was existed in spring all over the province ,other three seasons were central in middle Changchun area ,two season in summer and autumn were expanded to the east regions ,in winter was contracted to the middle region .关键词
