Abstract

In this paper, we prove the global regularity of smooth solutions to 2D surface quasi‐geostrophic (SQG) equations with supercritical dissipation for a class of large initial data, where the velocity and temperature can be arbitrarily large in spaces and . This result can be seen as an improvement work of Liu et al (2019) for it's without any smallness hypothesis of the norm of the initial data.
