Analysis the Typhoon Eyes of Megi from MTSAT Satellite Cloud Images with 3-D Profile Reconstruction

In this paper, image reconstruction technique (IRT) is used to reconstruct a 3-D profile of typhoons from MTSAT satellite cloud image data and based on a 1691 MHz receiver and iDAP system. The satellite cloud image data gives a single line profile slicing from a surface cloud image which does match the typhoon distribution. The line profile is presented with the temperature of the cloud top. The 3-D profiles of typhoons are constructed with the surface cloud images and the temperatures. IRT is conducted using the data of the 2010 Megi event. The typhoon feature is studied and the various typhoon eyes in three time intervals are analyzed. An effective early-warning system may become feasible based on this work. Lung-Chun Chang Ching Yun University, Taiwan
