A Comparison of HY-2 and QuikSCAT Vector Wind Products for Tropical Cyclone Track and Intensity Development Monitoring

China is the country worst affected by tropical cyclones in the Asia-Pacific region. The use of remote sensing data can help improve emergency preparedness for such events. In this letter, we evaluate the performance of HY-2 scatterometer data for monitoring Saola, Haikui, and Usagi typhoons, and consider QuikSCAT data for Florence, Ioke, and Gorden hurricanes. We use the means and standard deviation of the great circle distance to assess the typhoon track, and the t-test, mean error, and scatter index to evaluate the accuracy of typhoon intensity. Our results show that the HY-2 has the ability similar to that of QuikSCAT, suggesting that HY-2 has potential for application in typhoon monitoring.
