A MESSAGE FROM OUR PRESIDENT: April President's Message: May 5, 1989 Like many others in our field, I can point to a single day as the genesis of my career in weather. I had always enjoyed the weather and watching storms roll by, but that Friday night was different. A series of storms produced tornadoes across Georgia, the Carolinas, and Virginia, including one in my hometown of Clemmons, NC, and another, stronger tornado just up the road in Winston-Salem. I was just a little older than my oldest daughter is today, and I remember being scared — and worrying about our two outdoor cats — as we sheltered in the basement as the storms blew by. Other than a few loose objects being thrown around outside, we had no physical damage. (And our cats were fine.) I, on the other hand, spent the next couple of days being fairly jumpy at anything the sky did that wasn’t severe clear, but after the nerves settled, I realized I was

hooked.

While some of us can point back to a specific event, others point back to a movie. This month marked the 25th anniversary of Twister, a movie that noticeably boosted enrollment in meteorology programs in the years after its release. University of Georgia professor John Knox refers to this as “The Twister Effect”, and he even published about in it the Bulletin of the AMS a few years later.) As weather phenomena make for exciting movies and cool special effects, it’s likely other films since have had similar, if lesser, effects. These are just two of the many reasons why people have a fascination with the weather. Some have made it a career, others a hobby, and others still just enjoy sitting on the porch, watching the storms roll by. But for all of these groups, what an amazing time we live in! We didn’t own a computer back in 1989, but today, observations, remote sensing data, and weather forecast models are available not just on computers but on devices we all carry around in our pockets. This widespread availability of weather data has not been without some pain points, however. Anyone can access those datasets, but not everyone has the training or education to interpret them properly. We have plenty of examples of well-meaning folks who, in their zeal for learning and doing, or by simply sharing what they know with family and friends, end up sending the wrong message. Speaking for myself, I am certain that were I to grow up in this environment, I would have been one of these folks! Read More View the full May Newsletter.
