Figure 6From: A numerical experiment on the formation of the tropopause inversion layer associated with an explosive cyclogenesis: possible role of gravity waves Horizontal maps of ∂w/∂z at 260 hPa. Horizontal maps of ∂ w/∂ z at 260 hPa at t=(a) 24, (b) 27, (c) 30, (d) 33, and (e) 36 h.The line in (b) shows the position of the vertical section in Figure 7.Back to article page
