主 题:Deep learning meteorology precipitation nowcasting weather forecasting ZR formula
摘 要:Sudden precipitations may bring troubles or even huge harm to people’s daily *** a timely and accurate precipitation nowcasting is expected to be an indispensable part of our modern ***,the rainfall intensity estimation from weather radar is based on the relationship between radar reflectivity factor(Z)and rainfall rate(R),which is typically estimated by location-dependent experiential formula and arguably ***,in this paper,we propose a deep learning-based method to model the ZR *** evaluate,we conducted our experiment with the Shenzhen precipitation *** proposed a combined method of deep learning and the ZR relationship,and compared it with a traditional ZR equation,a ZR equation with its parameters estimated by the least square method,and a pure deep learning *** experimental results show that our combined model performsmuch better than the equation-based ZRformula and has the similar performance with a pure deep learning nowcasting model,both for all level precipitation and heavy ones only.
