Impact of EnKF assimilating Himawari-8 all-sky infrared radiance on the forecasting of a warm-sector rainstorm event
《Science China Earth Sciences》2024年第10期3110-3127,共18页Shanshan LOU Lei ZHU Xuexing QIU Guangzhou CHEN Song YUAN Shengnan ZHOU 
supported by the Jianghuai Meteorological Joint Project of Anhui Natural Science Foundation (Grant No.2208085UQ12)。
Warm-sector rainstorms are highly localized events, with weather systems and triggering mechanisms are not obvious,leading to limited forecasting capabilities in numerical models. Based on the ensemble Kalman filter(P...
