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 ...
Surface Energy Budget Over A Land Surface In The Tropics
(2009-05-21)
Atmospheric convection is sensitive to the nature of the surface and its temperature. Both dry (without cloud) and moist (with cloud) convections depend on the surface temperature. Surface temperature is of critical ...
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 ...
Effects of Arctic Geoengineering on Precipitation in the Tropical Monsoon Regions
(2018-06-14)
Arctic geoengineering wherein sunlight absorption is reduced only in the Arctic has been suggested as a remedial measure to counteract the on-going rapid climate change in the Arctic. Several modelling studies have shown ...
Mesoscale Turbulence on the Ocean Surface from Satellite Altimetry
(2018-06-26)
The dynamics captured in the ocean surface current data provided by satellite altimetry has been a subject of debate since the past decade. In particular, the contribution of surface and interior dynamics to altimetry ...
Assesment Of Air Quality And Anthropogenic Aerosol Fraction Over India Using Observations And Model
(2014-12-11)
Air quality degradation is emerging to be an issue of major concern in India. Recent investigations have shown that anthropogenic aerosols have significant impact on climate as well as on health. In fourth assessment report ...
Observed Subseasonal Variability Of Temperarture And Salinity In The Tropical Indian Ocean
(2013-06-10)
Subseasonal variability of tropical Indian Ocean sea surface temperature is thought to influence the active-break cycle of the Asian monsoon. There are several open questions related to the role of surface fluxes, large-scale ...
