| 摘 要： | 利用化州1959年以来的气温资料与ENSO资料,分析了化州近54a中寒潮及强冷空气爆发的天气气候特征和在全球大气环流和天气气候异常的大背景下,ENSO事件对影响化州的寒潮及强冷空气异常活动产生的作用,得到一些相关性的结论.统计分析表明,化州出现寒潮的拉尼娜影响年,其时拉尼娜事件爆发型均为东部型,强度中等或偏强,而化州出现寒潮的厄尔尼诺影响年,其时厄尔尼诺事件爆发型均为中部型,强度中等或偏弱.化州寒潮和强冷空气活动多的年份一般出现在中等或弱的厄尔尼诺事件期间或非ENSO年期间.少寒潮和强冷空气活动容易发生在拉尼娜事件影响年期间以及非ENSO事件影响年期间.

| Abstract: | Based on temperature data and ENSO data from 1959 in Huazhou, climate characteristics of cold wave and strong cold air outbreak during 54a were analyzed, and affection of ENSO events to abnormal cold and strong cold air activities under the background of global atmospheric circulation and climate anomalies to get some relevant conclusions. The result s showed that when a cold wave appeared in la Nina years, La Nina event breakout form was eastern type, and in moderate or strong intensity, when a cold wave appeared in el nino years, el nino event breakout form was central type, and in middle or weak strength. Cold wave and the strong cold air appeared more in the middle or weak el nino years or not ENSO years, on the contrary happened during la Nina event years t and ENSO years. |
