The Retrieval of Aerosols above Clouds and their Radiative Impact in Tropical Oceans
(2018-03-01)
Aerosols affect the global radiation budget which plays an important role in determining the state of the Earth's climate. The heterogeneous distribution of aerosols and the variety in their properties results in high ...
An Investigation On Role Of Surface Reflectance And Aerosol Model In Remote Sensing Of Aerosols From Moderate-Resolution Imaging Spectroradiometer Over India
(2010-07-21)
The Moderate-resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Terra and Aqua satellites have provided a global distribution of aerosols. The space-based inversion of MODIS measurements requires assumption about ...
Installation and Operation of Air-Sea Flux Measuring System on Board Indian Research Ships
(2018-07-04)
Exchange of mass (water vapor), momentum, and energy between atmosphere andocean has profound influence on weather and climate. This exchange takes place at the air-sea interface, which is part of the marine ...
Space-Time Evolution of the Intraseasonal Variability in the Indian Summer Monsoon and its Association with Extreme Rainfall Events : Observations and GCM Simulations
(2018-03-01)
In this thesis, we investigated modes of intraseasonal variability (ISV) observed in the Indian monsoon rainfall and how these modes modulate rainfall over India. We identified a decreasing trend in the intensity of ...
Influence of River Discharge on Climate in A Coupled Model
(2018-04-05)
River discharge can affect ocean surface temperature by altering stratification within the oceanic mixed layer. A hitherto unexplored aspect of present climate is the feedback of river runoff onto climate. This thesis ...
Role of Aerosols in Modulating the Intraseasonal Oscillations of Indian Summer Monsoon
(2017-12-05)
In this thesis, we have presented a systematic analysis of the change of cloud properties due to variation in aerosol concentration over Indian region using satellite observations, and Weather Research and Forecasting Model ...
Sensitivity of Sea Surface Temperature Intraseasonal Oscillation to Diurnal Atmospheric Forcings in an OGCM
(2018-04-05)
Abstract
The diurnal cycle is a dominant mode of sea surface temperature (SST) variability in trop-ical oceans, that influences air-sea interaction and climate processes. Diurnal variability of SST generally ranges from ...
Temporal Persistence and Spatial Coherence of Tropical Rainfall
(2018-01-01)
The work presented in the thesis focuses on systematically documenting the multi scale nature of the temporal persistence and spatial coherence of tropical rainfall. There are three parts to the thesis: The first two parts ...
A Method to Derive an Aerosol Composition from Downward Solar Spectral Fluxes at the Surface
(2018-01-01)
Aerosol properties are highly variable in space and time which makes the aerosol study more complex. The sources and production mechanism of aerosols decide the properties of the aerosols. Aerosol radiative forcing is ...
Formation and Maintenance of the Southern Bay of Bengal Cold Pool
(2018-06-11)
Around Sri Lanka and to the south of India sea surface temperatures (SST) are cooler compared to the surrounding region during summer monsoon. This region where SSTs are relatively cooler is known as the cold pool. Owing ...
