摘要
通过统计分析2008—2017年吉安国家基本气象站的常规观测气象资料与恶劣天气事件的发生情况,为江西省吉安桐枰通用机场二期扩建项目的建设提供基础气象数据与分析,从常规气象、极端气象角度分析机场二期扩建项目的可行性。结果发现:1)该地常年平均风力微弱,以N风向和NNW风向为主;2)常年平均气温19. 6℃,日最低气温历史极值为-4. 5℃,日最高气温历史极值为40. 7℃;3)降水集中在3―6月,年均降水量1 546. 4 mm,年均降水日数153 d;4)全年能见度较好,雷暴、积雪等恶劣天气发生概率较低且发生规律明显。
Based on the statistics of conventional observation data and the occurrence of severe weather events in Tongping basic weather station from 2008 to 2017,the research provided the basic meteorological data and analysis for the phase II expansion project in Tongping general airport of Jiangxi province.From the analysis of conventional and extreme meteorological elements,discussing the feasibility of the airport phase II expansion project.The results show that:1)the annual average wind is weak,and the wind direction is mainly N and NNW wind direction;2)The annual average temperature is 19.6℃,the historical extreme value of daily minimum temperature is-4.5℃,and the historical extreme value of daily maximum temperature is 40.7℃;3)The precipitation is concentrated from March to June,with an average annual precipitation of 1546.4 mm and an average annual precipitation days of 153 days;4)Visibility is good throughout the year,thunderstorms,snow and other severe weather occurrence probability is low and the occurrence regularity is obvious.
