Role of Interaction Between Magnetic Rossby Waves and Tachocline Differential Rotation in Producing Solar Seasons

Synoptic maps
Wednesday, January 24, 2018

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'.

An Observationally Constrained 3D Potential-Field Source-Surface Model for The Evolution of Longitude-Dependent Coronal Structures

Model output from the analysis of Carrington rotation 1912

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.

Analysis and Hindcast Experiments of the 2009 Sudden Stratospheric Warming in WACCMX+DART

Total electron content (TEC)
