Variation of Vorticity Gradient and Formation of Sunspots
Haibin Chen, Rong Wu
TL;DR
This paper investigates how variations in vorticity gradients within the solar troposphere influence the formation of sunspots, using a rotating turbulent thermal convection model and new convection criteria.
Contribution
It introduces a novel analysis linking vorticity gradient variations to sunspot formation based on an advanced convection model.
Findings
Vorticity gradient variations repress heat transport.
Sunspot formation is driven by vorticity gradient changes.
New convection criteria improve understanding of solar phenomena.
Abstract
Based on the rotating turbulent thermal convection model and using the rotating equivalent temperature assumption and new convection criterion, this paper analyzed the repression of the vorticity gradient on the heat transport and explained that the formation of sunspots originated from the variation of the vorticity gradient in the solar troposphere.
