Advances in Research of the Weather Radar Quantitative Precipitation Estimation

High-resolution weather radar data are needful for a wide range of use in meso-scale and micro-scale meteorology, in climatological applications and in high-resolution meteorological service. Since the last century, several countries have researched and developed multiple radar quantitative precipitation estimation (QPE) technologies and operation products, with the development of IT infrastructure and Doppler weather radar network. The recent advances in radar QPE researches and operation products are reviewed in this paper. There are some signi ficant advances such as Multi-Radar Multi-Sensor System (MRMS) that was developed at NSSL(National Severe Storms Laboratory) and went into NWS (National Weather Service) operations in USA in 2014. Then, QPE methods and operation products are compared between in China and abroad. Finally, the research plan of our radar QPE reanalysis is outlined.
