Southwestward propagating quasi-biweekly oscillations over the South-West Indian Ocean during boreal winter: Characteristics and propagation mechanism Open
An analysis of outgoing longwave radiation (OLR) and winds over the South-West Indian Ocean (SWIO) yields regular, poleward propagating, large-scale, convectively coupled systems of alternating cyclonic and anticyclonic circulation with a …

Northward Propagating Versus Non-propagating BSISO over South Asia: Horizontal Advection Driven Moisture Mode Within a Vertically Sheared Background Open
The Boreal Summer Intraseasonal Oscillation (BSISO) is a pronounced mode of tropical variability. Here, we identify two types of BSISO events, one which propagates northward over South Asia (SA) from the equatorial Indian Ocean (EIO), and …

Northward Prpogating BSISO over South Asia: connection between moisture advection and vortex tilting Open
The mechanism behind the northward propagation of the Boreal Summer Intraseasonal Oscillation (BSISO) over South Asia is still elusive, though many theories have been proposed to explain it. In this study, column- integrated moisture budge…

<p>An analysis of NOAA outgoing longwave radiation (OLR) data and NCEP-NCAR reanalysis winds spanning 10 years (2000/2001-2009/2010) over the South-West Indian Ocean (SWIO) yields regular, poleward propagating, large-scale, convectiv…

South-westward Propagating Quasi-biweekly Oscillation over South-western Indian Ocean during Boreal Winter Open
<div>The Quasi-Biweekly Oscillation (QBWO), with a period between the synoptic scale and the Madden Julian Oscillation (MJO), is an important component of tropical intraseasonal variability (ISV). While this mode has received a lot o…
