Bomb cyclones! Polar vortices! Atmospheric rivers! And rained out barbecues. One of the world’s leading Meteorologists, Dr. Marshall Shepherd – a former NASA scientist and current Professor of Geography and Atmospheric Sciences at the University of Georgia – is here to field a downpour of questions. We chat about percentages in forecasts, hail, sleet, storm chasing, heatwaves, fluid dynamics, TV weather people, climate change delayism and his favorite weather-themed movies. Also: what not to do with a weather balloon.
