Customization of WRF-ARW model with physical parameterization schemes for the simulation of tropical cyclones over North Indian Ocean

Osuri, Krishna; Mohanty, U.; Routray, A.; Kulkarni, Makarand - In: Natural Hazards 63 (2012) 3, pp. 1337-1359

The convection and planetary boundary layer (PBL) processes play significant role in the genesis and intensification of tropical cyclones (TCs). Several convection and PBL parameterization schemes incorporate these processes in the numerical weather prediction models. Therefore, a systematic...

An observational perspective on tropical cyclone activity over Indian seas in a warming environment

Mohanty, U.; Osuri, K.; Pattanayak, S.; Sinha, P. - In: Natural Hazards 63 (2012) 3, pp. 1319-1335

The genesis of tropical cyclones (TCs) over Indian seas comprising of Bay of Bengal (BoB) and Arabian Sea (AS) is highly seasonal with primary maximum in postmonsoon season (mid-September to December) and secondary maximum during premonsoon season (April and May). The present study is focused to...

Impact of sea surface temperature in modulating movement and intensity of tropical cyclones

Mandal, M.; Mohanty, U.; Sinha, P.; Ali, M. - In: Natural Hazards 41 (2007) 3, pp. 413-427

It is well recognized that sea surface temperature (SST) plays a dominant role in the formation and intensification of tropical cyclones. A number of observational/empirical studies were conducted at different basins to investigate the influence of SST on the intensification of tropical cyclones...
