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…

Eddy induced trapping and homogenization of freshwater in the Bay of Bengal
Nihar Paul, Jai Sukhatme, Debasis Sengupta +1
Freshwater from rivers influences Indian summer monsoon rainfall and regional tropical cyclones by shallowing the upper layer and warming the subsurface ocean in the Bay of Bengal.…
