Impact of 3D distribution of Black Carbon aerosols in the atmosphere on aerosol radiative forcing over the Indian region
Black Carbon (BC) aerosols are produced by the incomplete combustion of carbonaceous materials. While they constitute an insignificant mass-fraction of the composite atmospheric aerosols, their measurement is essential in ...
A Tropical Survey of Mid-Tropospheric Cyclones, their Classification and Genesis over the Arabian Sea
Middle Tropospheric Cyclones (MTCs) are moist synoptic tropical systems with vorticity maxima in the middle troposphere and weak signature in the lower troposphere. We begin with a tropical survey of MTCs; in South Asia, ...
Influence of Western Ghats Orography on Temporal and Spatial Distribution of Rainfall over South Asia
The Western Ghats (WG) orography that runs along the western coast of peninsular India, is a long
and narrow mountain chain with an average height of about 1200 meters. The orientation of this
orography is approximately ...
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 ...
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 ...
Ab initio Quantum Chemical Studies on Kinetic Fractionation during the analysis of Carbonates for the Clumped Isotope Thermometry
Stable and clumped isotopic compositions of molecules and minerals carry the signatures of temperatures and other physical and chemical conditions of the time of their formation. Isotopic compositions of such precipitate ...
On the spatial extent of extreme rainfall events over India during the summer monsoon
The spatial extent of extreme rainfall events directly affects the damages caused and
impacts of such events. However, it has been less explored in the literature. This thesis
examines extreme rainfall events of different ...
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 ...
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 ...
