呼伦贝尔一次暴雨的物理量诊断分析
|
摘要
利用NCEP再分析资料、区域自动站资料,从环流配置、物理量配置等对2018年7月呼伦贝尔地区一次暴雨天气进行了诊断,结果表明:在环流形势稳定的前提下,充沛的水汽输送,螺旋度的大值落区及高温高湿的能量锋区在暴雨区汇集,这样的物理量配置利于中、小尺度系统的发展,有助于暴雨产生。
Using NCEP reanalysis data and regional automatic station data, a stormy weather in Hulunbuir area was diagnosed in July 2018 from circulation configuration and physical quantity configuration. The results show that under the premise of stable circulation, abundant water vapor transport, the high value falling area of helicity and the energy front area of high temperature and high humidity gather in the rainstorm area, which is beneficial to the development of medium-and small-scale systems and to the occurrence of torrential rain.
