Periodic Cycles of Eyewall Convection Limit the Rapid Intensification of Typhoon Hato (2017)

Figure 8

Power spectrum of the cross-wavelet transform of the standardized ΔMSLP and eyewall averaged updraft at 200 hPa (equation (1)). The 90% significance level against red noise is shown as a thick contour, and the cone of influence, where edge effects might distort the picture, is shown as a lighter shade. The analyzed period is between the two white dotted lines.
