On Tuesday, March 5, at 8:00 pm Eastern/7:00 pm Central, join meteorologist Mark Thornton in this second in a series of four marine weather classes where he explores more deeply the forces controlling the wind, and then examines how new tools like Doppler radar can be used to see what's occurring in the atmosphere now. The first half of this class, The Invisible Forces Controlling the Wind, will explore the atmospheric forces that control the wind, including large-scale dynamics and small-scale features such as lake and land breezes. The second half of this session, Doppler Weather Radar will explore what Doppler weather radar offers the weather-savvy mariner. Don't miss Forces Controlling the Wind / Using Doppler Weather Radar.
