| Abstract: | Based on the observational data,the NCEP reanalysis data(1×1 deg) and the radar products,study is carried out of the causes of the heavy rainfall associated with typhoon FANAPI in Magui.The results show that the terrain effect,the low level jet flow,and the maintenance of surface mesoscale cyclone all made for the heavy rain in Magui.In addition,a large area of dry air layer occurred between 600 hPa and 400 hPa before the heavy rainevent,and gradually disappeared after the heavy rain event began,which exhibits some correlation between the dry air and the instable energy. |
