The Dependence of Northwest Pacific Tropical Cyclone Intensification Rates on Environmental Factors

Figure 9

The probability distribution of the three intensity change categories (SI, blue; NI, red; and RI, green), in each VWS bin (m s⁻¹): (a) deep-layer shear ; (b) upper-mid shear ; (c) mid-low shear ; (d) low-level shear . The thick and thin error bars are the 95% and 90% confidence intervals, respectively.
