Below is theschematic model of the gravity wave structure for a mature-stage multicellular squall line based on 2D simulation results. Updrafts greater 1 ms-1 are heavily shaded, and downdrafts less than 1 ms-1 arelightly shaded.Heavy line is the cold pool outline defined by the θ′=-1 K contour; cloud shield is defined by the 0.5 g kg-1 contour of nonprecipitating hydrometeor mixing ratio.
