| 摘 要： | 统计了河北省1998～2007年11月至翌年3月所出现的低温寡照过程，应用聚类分析方法，对重度低温寡照的欧亚范围内的逐日高空环流格点图进行分类。得出秋末至春初季节，造成河北省长时间连阴（雪或雾）天气的高空500hPa环流形势主要有冷低压型、低槽型和欧亚高压脊型3种类型。以2001年1月的低温寡照过程为例，分析了长时间连阴（雪或雾）天气下日光温室内的致灾环境及蔬菜表现。

| Abstract: | Through analyzing the data of low-temperature and overcast weather processes from November to next March from 1998 to 2007,it is found that the 500-hPa circulation patterns during continual overcast weather(snow,fog) in Hebei Province can be divided into three types on the Eurasian region from November to next March for each year: cold vortex,trough,and high-pressure.As a example,the disaster-inducing environment and the vegetable growing state in greenhouses during the process of low-temperature and overca... |
