An Assessment Of The Simulation Of Monsoon And Inter Tropical Convergence Zone In Coupled Ocean-Atmosphere Models
(2010-10-08)Monsoons and Intertropical Convergence Zones (ITCZ) exhibit variability at various temporal and spatial scales. The temporal scale of variability encompasses scales from the intraseasonal through interannual to interdecadal ... -
Extremes of Indian Summer Monsoon Rainfall and Equatorial Indian Ocean Oscillation
Our studies suggest that the equatorial Indian Ocean Oscillation, which is the atmospheric component of Indian Ocean Dipole, is as important as El Nino and Southern Oscillation for the interannual variation of Indian Summer ... -
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 ... -
Impact of Orography on the Simulation of Monsoon Climate in a General Circulation Model
(Indian Institute of Science, 2005-02-28)Orography plays a major role in the general circulation and climate of the tropics. Although many works have been done on the impact of global orography on summer monsoon, the previous studies have examined the impact on ... -
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 ... -
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 ... -
Multi-Scale Modeling of Moist Convection Over India
Clouds exist on all scales from turbulent processes to global scale and are organized on all the scales in between. They truly are multi-scale in nature. This makes them a very challenging simulation problem for atmospheric ... -
Simulations of Aerosol Species over the Indian Region: Evaluation and Improvements
Increasing aerosol loading over the south Asian region, holds a potential of, perturbing the south Asian monsoon system and the Himalayan glacial coverage, and thus affecting lives of (1/4)th of the world’s population. ... -
Time Splitting Methods Applied To A Nonlinear Advective Equation
(2009-03-09)Time splitting is a numerical procedure used in solution of partial differential equations whose solutions allow multiple time scales. Numerical schemes are split for handling the stiffness in equations, i.e. when there are ... -
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 ...
