Phase relation and energetics at the equator on day 10 in (a) Kuo simulation and (b) B-M simulation. Shown are generation of eddy available potential energy (G-EAPE), geopotential height (z), precipitation (pr), and boundary layer convergence (BL_cvg). All fields are normalized by their respective maxima at each panel. The origin of the zonal horizontal axis represents the location of maximum precipitation. σ represents the growth rate (unit 1/day) and τ represents the convective adjustment timescale (unit hour)
