1 INTRODUCTION The representation of the diurnal cycle of convection remains an open problem in numerical weather prediction (NWP) and climate simulations, especially over land (Bechtold et al., 2004; Krishna et al., 2021). Models tend to misrepresent the timing of convection initiation and maximum rainfall (Krishnamurti et al., 2007; Yuan et al., 2013), sometimes even missing the shallow convection stage completely and moving straight to the deep convection phase.

Keywords: Turbulence; Boundary layer; Subgrid-scale processes1. IntroductionAtmospheric modeling has come a long way since the early use of quasigeostrophic models to capture the synoptic-scale atmospheric dynamics, as first attempted in the mid-twentieth century (Charney et al. 1950; Bolin 1955).
