宣城春烟最佳移栽期天气气候分析
|
摘要
用1981-2010年安徽宣城气象资料和美国NCEP/NCAR全球日平均分析场资料,对宣城春烟最佳移栽期的天气气候进行分析.结果表明:(1)春烟最佳移栽期出现在3月下旬到4月中旬,4月上旬最多.(2)最佳移栽期出现前有一次强冷空气活动,降温和升压幅度大,影响过程时间短.(3)春烟最佳移栽期出现前后,多为偏东北风.(4)850hPa日平均温压场上,大陆高压减弱北缩,南部的暖平流向测站上空输送的趋势及气团受非绝热加热的影响,使得气温上升出现最佳移栽期.
In this paper,based on the data of meteorology in Xuancheng from 1981 to 2010,and NCEP/NCAR reanalysis day-to-day data,the weather and climatic characteristics of the best transplanting period of the spring tobacco in Xuancheng are analysed.The results are as follows.The best transplanting period of the spring tobacco was observed in late March to mid-April,and most of which appeared in early April.The best transplanting period of the spring tobacco appeared before a strong cold air activitys,which caused a large range of cooling and boost,and the influence period is short.Before and After spring tobacco transplanting period most of wind direction is partial NE.At 850hpa,the continental anticyclone weakened and North shrink.Warm advection from the south showed the trend to be transmited to the station,and the air mass was impacted by non-adiabatic heating. All of these made the rising of temperature and so the best transplanting period appeared.
