摘要
利用1980-2006年27年间黑龙江省林区发生的37次特大森林火灾资料,针对高空500hPa温压场的结构,将着火前3天短期时段内的天气形势分为4类8型,在此基础上对相对湿度与气温等因子的变化进行了分析,并对高火险日数及前期气候与大气环流特征进行了预报。
Based on the data about 37 violent forest fire in Heilongjiang forest region during 1980 -2006 and temPerature-pressure field structure of 500 hPa, this paper classifies the weather situation in three days before fires into 4 classes, analyzes the change of factors such as relative humidity and air temperature and forecasts days with high fire risk and the climatic and circulating characteristics in earlier stage.
