Latitudinal Change of Tropical Cyclone Maximum Intensity in the Western North Pacific

Figure 6

Same as in Figure 3, bur for (a) 200 hPa divergence and (b) vertical wind shear between 200 hPa and 850 hPa. Contour intervals are 2 ms⁻¹ for 200 hPa divergence and 0.5 ms⁻¹ for vertical wind shear between 200 hPa and 850 hPa. Shaded areas are significant at the 95% confidence level.

(a) 200 hPa divergence

(b) Vertical wind shear (200–850 hPa)
