汕头12月历史天气气候特点

Characteristics of Weather and Climate for Shantou in December

对汕头12月和原拟定第3届亚青赛(12月20—28日)历史同期的气温、降水、风、日照等气象要素进行气候特征分析,同时统计两次时段历史同期的天气事件频次。结果表明:12月为汕头冬季运动会的适宜举办月份,12月20—28日历史同期气候条件适宜活动开展,比赛受大风、暴雨等严重天气事件影响的概率很低;但中雨量级降水、中等强度冷空气及强冷空气过程发生的可能性较高,需考虑阶段性降温和降水对比赛的影响。

In this work,historical meteorological elements of air temperature,precipitation,wind and sunshine duration in Shantou for December and the originally scheduled duration for the third Asian Youth Games(from 20 to 28 December,2022)are analyzed and historical frequencies of weather events are statistically studied for the two periods.The results are shown as follows.December is the month suitable for Shantou to hold winter sporting games and December 20 to 28 is a period in which climatological conditions are suitable for sporting events due to low probability for such severe weather events as high wind and hard rain to occur.On the other hand,it is highly possible for precipitation at the moderate level and moderate and strong cold air processes to take place,making it necessary to take into account the effects of periodic temperature falls and rain on the games.
