The Dependence of Northwest Pacific Tropical Cyclone Intensification Rates on Environmental Factors
Figure 7
The change in environmental vertical wind shear (VWS, m s−1): (a) deep-layer shear , (b) upper-mid shear , (c) mid-low shear , (d) low-level shear of RI (green), NI (red), and SI (blue) process. 0 of x-axis is the onset time of RI, and −24 h, −18 h, −12 h, and −6 h are 24 hours, 18 hours, 12 hours, and 6 hours before intensification. The thick and thin error bars are the 95% and 90% confidence intervals, respectively.
