摘要
通过分析朝阳地区2011—2015年近100次强对流天气过程的雷达观测资料,统计出强对流天气的易发区,并结合地形对易发区的分布特征进行研究。结果表明,上游移入朝阳地区的强对流多在途经朝阳地区的行政边界沿线分布,当地新生的强对流易发区分布在朝阳境内山脉的迎风坡、山脉背风坡与沿河平原毗连地带、河流与丘陵相间分布的复杂地形区。
Through the analysis of nearly 100 strong convective weather process of radar observation data of Chaoyang district in 2011- 2015, we got the statistics of susceptible area of strong convective weather and combining the terrain to study the distribution characteristics of the susceptible area. The results showed that the strong convection from upstream of Chaoyang distribute along the border mostly, while the generated susceptible area of strong convection bad the distribution of the windward side of mountain, the adjoining area of the leeward of mountains and plains along the river, the complicated topographical of rivers and hills alternative distribution.
