Genesis of Tropical Cyclones from Tropical Cloud Clusters


Fig. Global locations of TCCs during 1982-2009. Blue colour dots indicate the positions of TCCs and red colour indicates the locations of TCCs that are developed into cyclogenesis


This study investigates the role of Tropical Cloud Clusters (TCCs) as precursors to tropical cyclones using nearly 30 years of satellite observations across major ocean basins. Results show that only about 5–6% of TCCs globally develop into tropical cyclones, with most clusters being small (100–200 km²). Cyclone formation occurs rapidly: nearly 48% within 24 hours and 85% within 84 hours of identification. Developing TCCs are embedded in more favourable environments, characterized by higher moisture, stronger upward motion, enhanced vorticity, and greater latent heat release. The study highlights size, lifetime and environmental controls on cyclone genesis. Read More..

About

NICES is a multi-institutional venture with participation of ISRO/DOS centres and other Departments and national Institutions under various Ministries which will help to strengthen the information base with contributions (in-situ observational and model outputs) from the participating organisations. NICES has been functioning under the guidance of NICES-Programme Management Council (PMC) with a composition of members from inter and intra-departmental institutions under the Chairmanship of Director, NRSC.

NICES envisages realisation of national level climate database generation, derived from Indian and other Earth Observation satellites from polar and geostationary missions for climate change impact assessment and mitigation.
