Numerical Simulations of the South American Low Level Jet in Two Episodes of MCSs: Sensitivity to PBL and Convective Parameterization Schemes

Figure 16

Time evolution of the spatial distribution of grid points from the ARW-WRF simulations where a LLJS was characterized from (a) 12Z 20 October 2008 (model initial condition) to (e) 12Z 22 October 2008 in 12 hr intervals. The color shading indicates, for the corresponding grid points, the percentage number of simulations employing the MYJ PBL parameterization scheme which generated a LLJS. The shading scale is indicated on the bottom of (a)–(e). The label “LLJ” [“X”] indicates an upper air meteorological station, where a LLJS was [was not] characterized.
