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 ...
Assessment of Direct Radiative Effects of Aerosols using Assimilated Datasets over the Indian Region
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 ...
Intraseasonal Variability in Aquaplanet Configuration of Community Atmosphere Model
The Intraseasonal Oscillation (ISO) plays an important role to modulate deep convective activity
in the tropical region. In this thesis, I aim to understand the role of land and warm oceans
in ISO, using a general ...
Vertical Structure of Convective Clouds Using the TRMM PR Data
Very small fractional area (0.1%) occupied by the cumulonimbus (Cb) clouds belies their
importance in Earths hydrological cycle and climate. For example, Riehl and Malkus
(1958) estimated that the vertical transport of ...
Impact of Local and Remote Land-Atmosphere Coupling on the Indian Summer Monsoon
India lies on the edge of the Asian summer monsoon domain and receives almost 80% of its annual rainfall during June to September (referred as Indian summer monsoon rainfall: ISMR). The dominant forcing behind inter-annual ...
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 ...
Effects of aerosols and atmospheric boundary layer dynamics on refractive index fluctuations: implications for Free-Space Optical communication
Laser communication through atmospheric channels is an emerging wireless technology, commonly known as Free-Space Optical (FSO) communication. It facilitates unprecedented channel capacity and very large bandwidth, favouring ...
