A Moisture-Vorticity Theory for the Boreal Summer Quasi-Biweekly Oscillation
Shubhrangshu Biswas, Jai Sukhatme, Bishakhdatta Gayen
We develop a moisture vorticity theory for the boreal summer quasi-biweekly oscillation (QBWO) in the tropics and analyze it with the aid of GPT-5.5. The model is formulated on a w…
Impact of Background Conditions on the Structure and Propagation of the Boreal Summer Quasi-Biweekly Oscillation
Shubhrangshu Biswas, Jai Sukhatme, Bishakhdatta Gayen
We examine the westward-propagating quasi-biweekly oscillation (QBWO) during boreal summer, with a focus on how background moisture and winds shape its structure and propagation. I…
Intraseasonal Equatorial Kelvin and Rossby Waves in Modern AI-ML Models
Shrutee Jalan, Jai Sukhatme
We examine the structure of large-scale convectively coupled Kelvin and Rossby waves in a suite of modern AI-ML models. In particular, multiple runs of PanguWeather, GraphCast, Fou…
Influx of Bay of Bengal waters and stirring trends in the Arabian Sea based on satellite altimetry
Nihar Paul, Manikandan Mathur, Jai Sukhatme +2
Freshwater export from the Bay of Bengal (BoB) can drive the regional air-sea interaction in the Arabian Sea (AS). We use AVISO geostrophic and Globcurrent velocities to characteri…
The role of tropical and extra-tropical waves in the Hadley circulation
ABS Thakur, Jai Sukhatme, Nili Harnik
The tropical overturning circulation is examined in a moist aquaplanet general circulation model forced using a non-interactive sea surface temperature (SST) distribution that vari…
Northward Propagating Versus Non-propagating BSISO over South Asia: Horizontal Advection Driven Moisture Mode Within a Vertically Sheared Background
Sambrita Ghatak, Jai Sukhatme
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 S…
