The reliable prediction of the South Asian monsoon rainfall and its variability is crucial for various hydrological applications and early warning systems. This study analyzes Global Fore- cast System (GFS) model generated ...

Uncertainties in estimation of radiative effects of aerosols, pose the primary challenge for the accurate climate impact assessment of aerosols. Especially, over the Indian region which is characterized by significant ...

The interpretation of proxies of paleo monsoons has been based primarily on changes in incident solar radiation. The role of feedbacks has not been examined in depth. In this thesis, we have used a diagnostic model of ...

The north Indian Ocean is one of the highly productive regions among the tropical oceans. Being a prominent monsoon regime, the basin exists as a highly dynamic region charac- terised by intense mixing and upwelling and ...

Free–space optical (FSO) communication is a wireless technology with an unguided laser signal carrying a large volume of data through the atmosphere. Numerous advantages such as higher bandwidth, high security, easy ...

Various aspects of dry and moist atmospheric dynamics are explored through systems of varying complexity, ranging from a 2-D shallow water model to a more complex 3-D general circulation model. First, we examine the response ...

The annual total continental runoff into the Bay of Bengal (BoB) is more than half the runoff into the entire tropical Indian Ocean. The net freshwater (FW) content in the Bay of Bengal mixed layer increases from a minimum ...

Our studies suggest that the equatorial Indian Ocean Oscillation, which is the atmospheric component of Indian Ocean Dipole, is as important as El Nino and Southern Oscillation for the interannual variation of Indian Summer ...

The east-west oriented cloud bands in the tropics are called the Inter-tropical Con-vergence Zones (ITCZ). Till recently, the ITCZ has been assumed to have a simple vertical structure with convergence near the surface ...

Deep convective clouds play an important role in global energy balance through vertical transport of water vapor, momentum and energy, altering radiation and also influence hydrological cycle via precipitation. These clouds ...
