Cloud Properties Over SHAR Region Derived From Weather RADAR Data
(2011-01-18)
Weather radars are increasingly used for the study of clouds, understanding the precipitation systems and also for forecasting very short range weather (one hour to a few hours). Now, Doppler Weather Radar (DWR) data are ...
Impact Of Dynamical Core And Diurnal Atmosphere Occean Coupling On Simulation Of Tropical Rainfall In CAM 3.1, AGCM
(2010-12-30)
In first part of the study we discuss impact of dynamical core in simulation of tropical rainfall. Over years many new dynamical cores have been developed for atmospheric models to increase efficiency and reduce numerical ...
A Variable Resolution Global Spectral Method With Finer Resolution Over The Tropics
(2010-11-19)
Variable resolution method helps to study the local scale phenomenon of interest within the context of global scale atmosphere/ocean dynamics. Global spectral methods based on spherical harmonics as basis functions are ...
Intraseasonal Variations In Sea Level Pressure And Association With Tropical Convection
(2010-07-19)
This thesis deals with tropical intraseasonal variation (TISV) having time scales in 20-80 day range. Variations on this time scale have been observed to have profound influence on the weather and climate of the entire ...
Aerosol Absorption And Source Characteristics Over Different Environments
(2010-11-02)
Extremely fine liquid droplets or solid particles, those remain suspended in the air, are known as aerosols. They are produced by natural sources and anthropogenic activities. Several types of aerosols produced by different ...
The Changing Nature Of Rainfall Annual Cycle And The Propagation Characteristics Of The Intraseasonal Oscillations In Flood And Drought Years Of The Indian Monsoon
(2010-08-30)
Using a 50-year (1951-2000) gridded (1-degree) daily rainfall data set over the Indian land region, we study two main aspects of the Indian monsoon. The first aspect deals with the changing nature of the rainfall annual ...
Changes In The Duration-Depth Characteristics Of Indian Monsoon Rainfall During 1951-2000
(2010-11-22)
Several previous studies have found that various characteristics of the Indian monsoon rainfall have shown secular changes over the past century. In this study, using a gridded (1degree) daily rainfall dataset, we analyse ...
Structure of the Tropical Easterly Jet in NCAR CAM-3.1 GCM
(2018-04-24)
This thesis examines the structure of the Tropical Easterly Jet (TEJ) in a General Circulation Model (GCM). The TEJ is observed only during the Indian summer monsoon period and is strongest during July and August. The jet ...
Biennial Oscillation Of Indian Summer Monsoon And Global Surface Climate In The Present Decade
(2010-12-08)
The ENSO-monsoon system is known to have a biennial component. Here we show using high resolution satellite data, mainly daily rainfall and sea surface temperature (SST) from the Tropical Rainfall Measuring Mission (TRMM), ...
