Paper Abstract

The socioeconomic aspects of life in coastal regions of India are significantly affected by tropical cyclones (TCs) over North Indian Ocean (NIO). It is well known that the lack of conventional observation over the ocean is a critical factor limiting the accuracy of the TC forecast. The goal of this study is to assess the impact of hyperspectral sounder measurements from Atmospheric Infrared Sounder (AIRS) and Infrared Atmospheric Sounding Interferometer (IASI) in the MetOp satellite on TC simulation using NCMRWF Unified Model (NCUM) with 17 km horizontal resolution. The results of the study indicate that the assimilation of hyperspectral radiance data has a positive impact on the prediction of track and intensity of TC.
