15.27. Kilpatrick

The purpose of this ktest is to simulate the response of the Atmospheric Boundary Layer 1d (ABL1d) model to a 2-dimensional (x-z) SST front. This ktest is based on Kilpatrick et al. [2014] case study (see also Spall [2007], Ayet and Redelsperger [2019], Lemarié et al. [2021]).

Description of the ABL1d model can be found in Lemarié et al. [2021]. Same version of the ABL1d model described in this paper has been implemented in CROCO.
