Description

Thunderstorms can quickly spoil an outing in many ways—strong winds, large waves, dangerous lightning, waterspouts, or visibility-limiting rain. This four-hour clinic will examine the various types of thunderstorms and the ingredients that lead to their formation. The clinic will cover why thunderstorms often ‘pop-up’ late on summer afternoons and why some storms have short life-spans while others persist for several hours. The clinic will also introduce the many readily-available resources for forecasting and monitoring thunderstorms.

You will learn the following at the webinar series:

  • A few basic weather principles.
  • How to decode the confusing symbols, color shading, and meteorological shorthand on weather forecast maps.
  • How to recognize the large and small-scale weather patterns that promote thunderstorm development.
  • The ingredients needed for thunderstorm development and their life-cycle.
  • How to forecast the potential and nature of severe weather.
  • The dynamics of lightning and a review of the latest advice on lightning protection for your boat.
  • How to use Doppler Weather Radar to assess the development, monitor the evolution, and track the movement of thunderstorms.
  • The terminology used by the National Weather Service during hazardous and severe weather events.

The four-hour live webinar series combines classroom instruction, case studies, and exercises to create an engaging learning experience.
