| Figure 3.3.9(a) |
Radar reflectivity images at 10:30 p.m. on 23 July 2012: horizontal cross-section taken at an altitude of 15.5 km. The arrow points to an area of intense convection on the eyewall of Vicente (grey shadings south of Hong Kong in the image). This signifies the existence of violent updraft raising cloud water to the top of the troposphere. |
