We demonstrate a novel physical mechanism, namely, that a “solar tsunami” occurring in the Sun’s interior shear-fluid layer can trigger new cycle’s magnetic flux emergence at high latitudes, a few weeks after the cessation of old cycle’s flux emergence near the equator.

Mausumi Dikpati presents a nonlinear magnetohydrodynamic shallow-water model for the solar tachocline (MHD-SWT) that generates quasi-periodic tachocline nonlinear oscillations (TNOs) that can be identified with the recently discovered solar 'seasons'.

Mausumi Dikpati explains the challenge of creating synoptic maps of the photosphere that reliably reflect conditions at all locations concurrently is a major limitation to progress in this area.

A 3D Potential-Field Source-Surface Model for the Evolution of Longitude-Dependent Coronal Structures: We explore a complementary approach to traditional magnetogram-based coronal field solutions.

We implement an Ensemble Kalman Filter procedure using the Data Assimilation Research Testbed for assimilating "synthetic" meridional flow-speed data in a Babcock–Leighton-type flux-transport solar dynamo model.
