基于自动站观测资料的朝阳地区强对流空间分布规律研究

Research on the Spatial Distribution of Strong Convective Weather in Chaoyang District Based on the Observation Data of Automatic Weather Stations

通过对2011—2016年朝阳地区140个区域自动站观测资料进行筛选统计,得出强对流事件出现的总次数,绘制短时强降水和对流性大风的频发区空间分布图。结果表明,短时强降水主要分布在山地的迎风坡、河流与丘陵复杂分布的地区。对流性大风有三大块频发区,受山脉的阻挡和影响,对流性大风频发区集中分布于山谷、河流等地势平坦地区。

Through the analysis of observation data based on 140 regional automatic weather stations in Chaoyang area from 2011 to 2016, the total number of strong convection events was obtained, and the spatial distribution of frequent areas of short-term heavy precipitation and convective winds was mapped. The results showed that short-term heavy precipitation was mainly distributed in windward slopes, rivers and hills in mountainous areas.There were three major block frequency areas for convective winds. Due to the obstruction and influence of the mountains, the convective wind areas were concentrated in flat areas such as valleys and rivers.
