Monitoring and Forecasting of Extreme Weather Systems by Using Satellite Remote Sensing Technology Gin-Rong Liu Vice-President, National Central University (NCU) Distinguished Professor, NCU Professor, Center for Space and Remote Sensing Research; Department of Atmospheric Sciences; Institute of Hydrological and Oceanic Sciences; Master of Science Program in Remote Sensing Science and Technology 1 E-mail : GRLiu@.tw Outline I. Introduction II. Mesoscale Convective Systems III. Typhoons V. Conclusion 2 I. Introduction Satellites are versatile and powerful tools. The followings demonstrate that satellite applications in two main extreme and disastrous weather systems, mesoscale convective systems and typhoons. 3 II. Mesoscale Convective Systems (MCSs) Motivation: To foresee a MCS’ formation and development in Mei-Yu season. 4 Liu et al. (2002, 2006, 2009) used satellite derived air-sea parameters to establish the Objective Potential Index (OPI), to serve as an indicator for detecting the formation and development of MCSs. 5 Retrieved results of Ts and Ta SSM/I Ts (C) SSM/I Ta (C) 6 (continued) Qa and (Ts-Ta) SSM/I Qa (g/kg) SSM/I Ts-Ta (C)
