摘要

利用INSAT-3D卫星分析了2020年5月20日横越西孟加拉邦-孟加拉国海岸的超级气旋风暴(SuCS) AMPHAN的特征特征。无源微波(PMW)图像，特别强调眼睛特征及其与强度的关系。对这些卫星图像/产品进行分析，以确定气旋的中心、强度和气旋眼的特征。它显示了SuCS强度随“眼”几何和热特性的特征变化。气旋风眼特征的精确变化可用于气旋强度的短期预报。

Characteristic features of Super Cyclone ‘AMPHAN’- observed through satellite images

Characteristic features of Super Cyclonic Storm (SuCS), AMPHAN which crossed West Bengal-Bangladesh Coast on May 20, 2020 have been analyzed based on INSAT-3D & passive microwave (PMW) images with special emphasis on eye characteristics and its relationship with intensity. These satellite images/products are analyzed to determine the centre of the cyclone, its intensity and the characteristics of the eye of the cyclone. It shows the characteristic variation of intensity of SuCS with geometric and thermal characteristics of the ‘eye’. Precise changes in the eye features of the cyclone can be used for very short-range forecasting of the intensity of the cyclone.

期刊介绍： Tropical Cyclone Research and Review is an international journal focusing on tropical cyclone monitoring, forecasting, and research as well as associated hydrological effects and disaster risk reduction. This journal is edited and published by the ESCAP/WMO Typhoon Committee (TC) and the Shanghai Typhoon Institute of the China Meteorology Administration (STI/CMA). Contributions from all tropical cyclone basins are welcome. Scope of the journal includes: • Reviews of tropical cyclones exhibiting unusual characteristics or behavior or resulting in disastrous impacts on Typhoon Committee Members and other regional WMO bodies • Advances in applied and basic tropical cyclone research or technology to improve tropical cyclone forecasts and warnings • Basic theoretical studies of tropical cyclones • Event reports, compelling images, and topic review reports of tropical cyclones • Impacts, risk assessments, and risk management techniques related to tropical cyclones
