摘要
根据1960—2020年都安碳酸钙工业区周边的历史气象灾害以及工业区内重点企业对气象要素和高影响天气的抽样调查,确定影响工业区的关键气象因子为降水、气温、风速,高影响天气为暴雨、雷暴、大风、潮湿天气、高温。1960—2020年都安站气象统计资料显示:年平均暴雨日数为7.6 d,各月份均有可能出现暴雨天气,5—8月为暴雨多发期,其中6—7月最为集中,每年的5—9月为雷暴的高发期,其中6—8月最为频繁,21:00至翌日07:00为雷电活动高发期,年平均大风日数为3.4 d,月最大风速在12.4~22.7 m/s之间,年极大风速在17.4~26.9 m/s之间,年平均潮湿寡照日数为83.0 d。潮湿寡照日数主要集中多分布在1—4月,最多的月份出现在3月,平均年高温日数为17.1d,高温日数最多的月份出现在6—9月,其中8月最多。
According to the historical meteorological disasters around the Du’an Calcium Carbonate Industrial Zone from 1960 to 2020 and the sampling survey of meteorological elements and high impact weather by key enterprises in the industrial zone,the key meteorological factors affecting the industrial zone are determined to be precipitation,temperature and wind speed,and the high impact weather is rainstorm,thunderstorm,gale,humid weather and high temperature.According to the meteorological statistics of Du’an Station from 1960 to 2020,the annual average number of rainstorm days was 7.6 days,and rainstorm weather may occur in all months.May August was a period of frequent rainstorm,of which June July was the most concentrated period.May September of each year was a period of high thunderstorm occurrence,of which June August was the most frequent period.From 21:00 to 07:00 of the next day was a period of high thunderstorm activity.The annual average number of strong wind days was 3.4 days,and the maximum monthly wind speed was between 12.4 m/s and 22.7 m/s,The annual maximum wind speed ranges from 17.4 to 26.9 m/s,and the average number of wet and sunny days was 83.0 days.The number of humid and sunny days was mainly concentrated from January to April,with the most frequent month occurring in March,with an average annual high temperature day of 17.1 days.The month with the most high temperature days occurs from June to September,with August being the most abundant.
