Abstract
Tropical cyclones are also known as typhoons or hurricanes. Also, special emphasis is given on the various aspects associated with cyclogenesis, like the six essential parameters required for cyclogenesis as given by W. M. Grey, and Dvorak technique is discussed in this chapter. INSAT-3D is an indigenous advanced dedicated meteorological satellite in geostationary orbit, which was launched on 26th July 2013. INSAT-3D was declared operational by IMD on 15th January 2014. INSAT-3D has four payloads, namely. IMAGER, SOUNDER, data relay transponder (DRT), and satellite aided search, aid and rescue (SAR). Three rainfall estimates are being generated from INSAT-3D, namely, hydro-estimator (HE), INSAT multispectral rainfall algorithm (IMSRA), and QPE (quantitative precipitation estimate). It has been found in this study that IMSRA performs better during initial stages of cyclogenesis (i.e., during T1.0, T1.5, and T2.0); during mature stages T2.5 to T3.0, HE performs better. During weakening stages IMSRA gives better results.
