Abstract

In this paper, we perform a three-stage numerical relay to investigate the finite time singularity in the two-dimensional Boussinesq approximation equations. The initial asymmetric condition is the middle-stage output of a 2048² run, the highest resolution in our study is 40960², and some signals of numerical blowup are observed.
