池州市2018年冬季连阴雨气候特征及其对农业生产的影响
|
摘要
基于当地气象台站的逐日降水、日照及气温等资料,对2018年12月至2019年2月池州市出现的历史上罕见的冬季连阴雨天气特征进行分析。结果表明,整个冬季气候呈"两多一少一低"特征,即降水累积量多、阴雨日数多、光照稀少,同时,气温比常年偏低。此次连阴雨天气对农业的影响表现在不少农田湿渍害严重,农业气象灾害指标超过1960年以来历史同期极值。
Based on the data of daily precipitation, sunshine and temperature,the characteristics of the rare continuous rainy weather in winter from December2018 to February 2019 in Chizhou was analyzed. The results showed that there were more precipitation accumulations,more rainy days and less light in winter.Meanwhile, the temperature was lower than other years. The impact of continuous rainy weather on agriculture was manifested in the serious wet damage to farmland. The index of agrometeorological disasters had exceeded the historical extreme since 1960.
