摘要
为了做好二十四节气与肇庆气象的相关服务工作,利用肇庆6个国家基准气象观测站30年资料,基于气温、降雨等气候因子对肇庆进行四季划分,并分析了肇庆二十四节气特征。结果表明:肇庆二十四节气中立春日与肇庆平均入春时间最为接近,平均入夏时间接近清明日。除高要外其他地区平均入秋时间与霜降日接近,高要接近立冬日入秋。肇庆各地平均入冬时间接近小寒日、大寒日。肇庆一年中最热在大暑、小暑,最冷在大寒、小寒节气。谷雨节气升温幅度最大,霜降节气降温幅度最大。肇庆高温天气集中在立夏到秋分之间,霜降节气不再出现高温天气。从立春开始肇庆降雨逐渐增加,在清明节气期间有小幅的回落,芒种节气降雨最多,后呈波动下降,霜降节气降雨最少。肇庆初雷日比惊蛰节气早约一个节气时间。清明节气平均降雨日数8.2 d,清明节遇雨概率为53.8%。
In order to do a good job in the 24 solar terms related meteorological services in Zhaoqing,the 30-year data of six national benchmark meteorological observation stations in the city were used to divide the four seasons based on the climate factors such as temperature and rainfall,and the characteristics of the 24 solar terms in Zhaoqing were analyzed.The results are shown as follows.For the 24 solar terms of Zhaoqing,the Beginning of Spring(1st solar term)is the closest to the average spring onset time of the city and its average summer onset date is close to the Pure Brightness(5th solar term).Except for the area of Gaoyao,the average autumn onset date for the remaining parts of the city is close to the Frost's Decent(18th solar term),while Gaoyao's autumn begins near the Beginning of Winter(19th solar term).The average winter onset date in Zhaoqing is close to the Lesser Cold and Greater Cold(23rd and 24th solar terms,respectively).For the city,the hottest time of the year is in the Lesser Heat and Greater Heat(11th and 12th solar terms,respectively),and the coldest in the Lesser Cold and Greater Cold.The Grain Rain(6th solar term)is accompanied with the most temperature rise,while the Frost's Decent witnesses the most temperature drop.The high temperature weather in Zhaoqing is concentrated between the Beginning of Summer(7th solar term)and the Autumn Equinox(16th solar term),and comes to an end in the Frost's Descent.After the Beginning of Spring,the rainfall in Zhaoqing gradually increases,drops a little during the Pure Brightness and peaks in the Grain in Beard(9th solar term)before declining in fluctuation afterwards,and the rainfall is the least in the Frost's Descent.For Zhaoqing,the first thunder day of the year is about one solar term earlier than the Waking of Insects(3rd solar term).For the Pure Brightness,the average number of rainfall days is 8.2 d,and the probability of rain is 53.8%.
