摘要
Abstract
Numerical weather products, automatic observation station data, satellite images and Doppler radar data were used to analyze circulation situation field characteristics during storm, heavy rain process and thermodynamics, dynamics and radar echo characteristics of meso-and micro-scale physical quantity on June 30, 2010 in Anyang, the results indicate that the changes of automatic observation station data can be well reflected in changes in surface convergence line with the changes and movement of rain trends; ever-increasing radial flow for the heavy rainfall in the southwest provided sufficient moisture; surface layer easterlies ground invasion and pre-warming for the heavy rain continued to provide a high energy unstably; the stronger the precipitation generated the more the release of latent heat of condensation, which played a driving role for the development of meso-scale convergence.关键词
