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 ...
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 ...
Dynamics of river plumes in the Bay of Bengal
The Bay of Bengal (BoB) receives a large amount of freshwater through runoff from sev-
eral rivers along its border. This large freshwater gain has severe implications on the
dynamics and thermodynamics of the BoB as ...
Stirring and mixing driven by mesoscale eddies in the stratified Bay of Bengal
The stirring of passive tracers driven by altimetry-derived daily surface geostrophic currents is studied on subseasonal timescales in the Bay of Bengal. Advection of latitudinal and longitudinal bands highlights the chaotic ...
Bay of Bengal Freshwater in the tropical Indian Ocean
The annual total continental runoff into the Bay of Bengal (BoB) is more than half the runoff into the entire tropical Indian Ocean. The net freshwater (FW) content in the Bay of Bengal mixed layer increases from a minimum ...
Moist and Dry Dynamics in Shallow Water and General Circulation Models
Various aspects of dry and moist atmospheric dynamics are explored through systems of varying complexity, ranging from a 2-D shallow water model to a more complex 3-D general circulation model. First, we examine the response ...
Estimation of Glacier Mass Balance at Basin Scale in the Himalaya for Recent Decades and Future
The Himalayan glaciers are a major source of perennial river systems which support the livelihood of millions of people in south Asia. Therefore, it is important to understand changes in water resources due to changes in ...
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), ...
Variation Of Marine Boundary Layer Characteristic Over Bay Of Bengal And Arabian Sea
(2016-05-04)
The atmospheric boundary layer (ABL) is the lowest layer of the atmosphere where surface effects are felt on time scales of about an hour. While its properties are determined by the surface characteristics, season and ...
