Figure 7From: A numerical experiment on the formation of the tropopause inversion layer associated with an explosive cyclogenesis: possible role of gravity waves Vertical cross sections of ∂w/∂z and N2 . Vertical cross sections of ∂ w/∂ z (color, s −1) and N2 (contour, s −2) at t=27 h along the line shown in Figure 6b. Tropopause is denoted by the green line. The dashed-dotted line shows the 260 hPa level.Back to article page
