| 摘 要： | 利用辽宁省1961~2005年39个气象观测站的常规地面观测资料,采用趋势分析等统计方法,分析了辽宁省近45年的气候变化特征。采用沙道夫干湿指数分析了辽宁省近45年的旱涝变化趋势;同时研究了辽宁省夏季低温冷害和沙尘天气的变化。结果表明,近45年来辽宁气温升高、降水减少,气候向暖干化方向发展。在气候变暖背景下,近45年来辽宁的干旱有增加趋势、洪涝减少,夏季低温冷害明显减少,沙尘日数减少。

| Abstract: | Based on tendency analysis,the climate change characteristics of the recent 45 years in Liaoning province are analyzed by using the data of 39 weather stations from 1961 to 2005.Changes of some meteorological disasters,such as drought,flooding,summer low temperature cold damage and dust storm during in the recent 45 years in Liaoning are studied by using indices of aridity and wetness.The results show a tendency of temperature increase,precipitation decreases and climate warming in the recent 45 years in Liaoning.Under the background of climate warming,there is an increasing tendency of drought and a trend of decrease in flood-waterlogging,summer freezing damage and the number of sand-dust day. |
