影响靖宇地区温带气旋的统计分析

Statistics and Analysis of Extratropical Cyclones Over Jingyu Area

核电站因它不排放如二氧化碳这样的温室气体,核电对降低能源部门的碳密集作出了贡献,因此愈益受到人们的重视。在对核电站地区的天气、气候环境进行分析的基础上,对影响靖宇核电站地区的温带气旋作了研究。结果表明:1949—2007年期间影响靖宇地区的温带气旋计111个;受温带气旋影响的年数有41年(约2/3)。影响靖宇地区且产生强降雨的温带气旋,主要发生在6、7、8月这3个月,并且一半以上出现在7月。影响靖宇地区的温带气旋大部分是东北气旋,占总数的65%;蒙古气旋与华北气旋次之。此外,对造成严重影响的温带气旋的个例也从天气学角度进行了分析。

Nuclear power stations do not release greenhouse gases,such as carbon dioxide,and thus make the contribution to reducing the carbon density of energy products.Therefore,it gets increasingly attentions of people.In view of analyzing the weather and climate environment around nuclear power station area,the study of extratropical cyclones that influence Jingyu nuclear power station area has been made.The result shows： there were 111 extratropical cyclones totally that influence Jingyu area from 1949 to 2007.There were 41 years that were influenced by the extratropical cyclones（approximately 2/3）.The extratropical cyclones that influence Jingyu area and produce strong rainfall,mainly occurred in June,July and August,more than half of them were in July.Most of the extratropical cyclones that influence Jingyu area were Northeast cyclone,which is 65% of the total;what followed behind it were Mongolian cyclone and North China cyclone;Jianghuai cyclone is the last one.Extratropical cyclones cause severe rainfall and gale disasters,some weather disasters are extremely serious.Of them a case study of the extratropical cyclone was also made from synoptic analysis.
