Abstract: | With Doppler radar data from Shantou and Xiamen and the National Centers for Environmental Prediction and the National Center for Atmospheric Research(NCEP/NCAR) reanalysis data,the characteristics of a short-term heavy rainstorm on 17 May 2006 caused by Typhoon Chanchu are studied.Doppler radar data indicates that during the period from 1800 to 1900 May 17,the azimuthal phases of the positive and negative radial wind maximums are asymmetric around the core radius of the typhoon,i.e.,the radial wind on the ... |
