The analysis on the data collected by the Central Weather Bureaus Chiku weather radar and automatic rainfall rate measurement is to identify the characteristics of rainbands under the influence of typhoon-induced southwest flow.There are 2 case studies,including Sepat (2007) and Kalmaegi(2008),for recognizing the pattern of convective rainbands associated with typhoon-induced southwest flow.The preliminary result shows The rainbands evolve into linear convections with north-south orientation after propagating inland.The line echoes in the case of Typhoon Sepat are well organized,which are similar to the squall line and oriented to northwest-southeast.Severe convections associated with typhoon Kalmaegi develop on the upslope over the southwestern Taiwan.Later on they extend to central Taiwan and elongate over 9 hr.
