Linking typhoon tracks with rainfall patterns and flood timing



Being able to predict the timing and amount of flooding during and following a hurricane or typhoon would improve early warning and mitigation efforts. However, variable typhoon tracks and interaction between typhoons and varied landscapes make flood prediction challenging. Huang et al. investigated the detailed distribution of typhoon-induced rainfall over a mesoscale mountainous watershed located in eastern Taiwan, a region that is regularly affected by severe typhoons—losses associated with typhoons in Taiwan can reach $500 million per year. The researchers analyzed high-resolution radar observations of 38 rainfall events during 2000–2010 in eastern Taiwan to study the relationship between typhoon track, rainfall patterns, and the timing of peak flooding.
