Figure 4

Time-height cross sections of area-mean$\overline{{\mathit{\theta }}^{\prime }{\mathit{w}}^{\prime }}$(upper panels) and$\overline{{\mathit{q}}^{\prime }{\mathit{w}}^{\prime }}$(lower panels). These fluxes normalized by maximum flux magnitudes in Figure 3 are calculated from the experiments under the condition U _Z  = 0 m · s^–1 · km^–1 for (a) case A02, (b) case A10, and (c) case A20. Thick contours in upper and lower panels show area-mean potential temperature (K) and mixing ratio (q × 10⁶; kg · kg^–1), respectively. Thin-dashed contours indicate negative values of normalized $\overline{{\mathit{\theta }}^{\prime }{\mathit{w}}^{\prime }}$.
