Impact of mesoscale-synoptic scale interactionson the Mumbai historical rain event during26-27 July 2005

摘要

The exceptionally heavy rainfall event during 26-27July 2005 over Mumbai and Thane districts has beenanalysed in this article to identify the meteorologicalconditions that possibly caused the phenomenallyheavy rainfall. Using satellite and radar inputs combined with synoptic and thermodynamic analysis, it isfound that formation of mesoscale convective systemsover Mumbai, comprising super thunderstorm cells andtheir interaction with the synoptic scale low-pressurearea from the Bay of Bengal led to the concentratedvery high intensity rainfall.
