2015年8月3～4日辽宁省东南部强降水天气过程分析

摘要

利用卫星雷达资料、加密自动站雨情和实况资料，从环流形势、中尺度分析等方面对2015年8月3～4日辽宁省东南部强降水天气过程进行了分析。结果表明，此次过程是低涡、低空急流和低空切变线及蒙古气旋相互作用下形成的暴雨天气过程。从雷达产品的分析入手可以较早且较准确地发现强对流发生的时间和地点，提高短时强降水预报和预警的准确率。%By using satellite radar data, rainfall data and observation data of encryption automatic weather station, the heavy precipitation process in the southeast of Liaoning Province during Aug.3-4, 2015 was analyzed from aspects of circulation situation and mesoscale analy-sis.The results showed that the heavy rainfall process was generated by the interaction of vortex, level jet stream, low level shear line, Mongo-lia cyclones.According to the analysis of radar products, it was found that the occurrence time and place of strong convection can be found earlier and more accurately, and the accuracy of short term precipitation forecasting and early warning can be improved.
