Dynamics of river plumes in the Bay of Bengal
The Bay of Bengal (BoB) receives a large amount of freshwater through runoff from sev-
eral rivers along its border. This large freshwater gain has severe implications on the
dynamics and thermodynamics of the BoB as ...
Stirring and mixing driven by mesoscale eddies in the stratified Bay of Bengal
The stirring of passive tracers driven by altimetry-derived daily surface geostrophic currents is studied on subseasonal timescales in the Bay of Bengal. Advection of latitudinal and longitudinal bands highlights the chaotic ...
Moist and Dry Dynamics in Shallow Water and General Circulation Models
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 ...
Estimation of Glacier Mass Balance at Basin Scale in the Himalaya for Recent Decades and Future
The Himalayan glaciers are a major source of perennial river systems which support the livelihood of millions of people in south Asia. Therefore, it is important to understand changes in water resources due to changes in ...
Simulations of Aerosol Species over the Indian Region: Evaluation and Improvements
Increasing aerosol loading over the south Asian region, holds a potential of, perturbing the south Asian monsoon system and the Himalayan glacial coverage, and thus affecting lives of (1/4)th of the world’s population. ...
Effect of Rainfall and River Discharge on the North Indian Ocean
In the north Indian Ocean, the Bay of Bengal (BoB or bay) and the Eastern Arabian Sea (EAS) receive a huge amount of rainfall during summer. Several rivers along their boundaries discharge enormous amounts of freshwater ...
Impact of river runoff into the ocean on climate in a coupled model
In order to study the impact of global runoff, sensitivity experiment (NoRiv) was carried out
by shutting down the entire runoff into the ocean for a period of 200 years. The changes in
NoRiv, compared to the reference ...
Space-time variability of near-surface salinity in the Bay of Bengal
Freshwater from monsoon rain and rivers leads to a 5-10 m deep low-salinity layer in the north Bay of Bengal from August to February. The thin fresh layer, with strong stratification at its base, is highly responsive to ...
Physical controls of chlorophyll distribution in the North Indian Ocean
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 ...
Energetics of monsoon variability over the last 22,000 years
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 ...
