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 ... -
An Ocean General Circulation Model Study Of The Arabian Sea Mini Warm Pool
(2009-07-17)The most important component of the climate system over the Indian Ocean region is the southwest monsoon, which dictates the life and economy of billions of people in the tropics. Being a phenomena that involves interaction ... -
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 ... -
Air-Sea Flux Measurements Over The Bay Of Bengal During A Summer Monsoon
(2009-03-19)Majority of the rain producing monsoon systems in India form or intensify over the Bay of Bengal and move onto the land. We expect the air-sea interaction to be a crucial factor in the frequent genesis and intensification ... -
Extended Range Predictability And Prediction Of Indian Summer Monsoon
(2009-03-17)Indian summer monsoon (ISM) is an important component of the tropical climate system, known for its regular seasonality and abundance of rainfall over the country. The droughts and floods associated with the year-to-year ... -
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 ... -
Data Assimilation Experiments Using An Indian Ocean General Circulation Model
(2008-09-09)Today, ocean modeling is fast developing as a versatile tool for the study of earth’s climate, local marine ecosystems and coastal engineering applications. Though the field of ocean modeling began in the early 1950s along ... -
Intraseasonal Variability Of The Equatorial Indian Ocean Circulation
(Indian Institute Of Science, 2004-10)Climatological winds over the equatorial Indian Ocean (EqlO) are westerly most of the year. Twice a year, in April-May ("spring") and October-December ("fall"), strong, sustained westerly winds generate eastward equatorial ... -
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 ...
