大兴安岭地区近30a大风天气变化的特征分析

摘要

The characteristics of the geographic distribution of gale weather and the months, seasons and age change distribution were analyzed statistically with 6 counties' (districts) meteorological data from 1979 to 2008 in Daxinganling region. Furthermore, the geographic distribution and variation rule of gale weather were studied by aspects of the terrain, the geographical environment condition and the transformation characteristic of atmospheric circulation in order to provide better climate background for gale weather forecast.%本文利用大兴安岭地区1979—2008年6个县（区）的气象资料，对大兴安岭地区大风天气发生的地理分布和月、季、年代的变化分布特征进行了统计分析，并对其大风天气的地理分布特征及变化规律从地形、地理环境条件及大气环流转换等方面作了进一步的研究，以便更好的为大风天气的预报提供气候背景。
