摘要: 利用1962-2008年洱海水面蒸发量资料和大理气象观测资料,基于气候变暖背景下,对洱海水面蒸发量的变化及影响洱海水面蒸发量变化的直接气候因子进行分析。结果表明:随着气候变暖,洱海水面蒸发量不仅没有增加反而呈现减少趋势,洱海水面蒸发量和气温的相关性并不显著。洱海水面蒸发随着总云量和相对湿度的增加而减小,随着平均风速和日照时数的增大而增大。引起洱海水面蒸发量逐步减少的主要原因是总云量呈增多趋势。

Abstract: Based on the evaporation of Erhai Lake from 1962 to 2008 and the observation data in Dali weather station, evaporation variation and related direct climatic factors influencing evaporation were analyzed. The results indicate that evaporation from Erhai Lake takes on the decreasing trend with climatic warming, and the relationship between water surface evaporation and air temperature is not significant. Evaporation from Erhai Lake decreases with the increase of total cloud cover and relative humidity, and it increases with the increase of mean wind speed and sunshine duration. The main reason causing the decrease of evaporation from Erhai Lake is the increase of total cloud cover.
