How do you spend your Thursday nights? Stuck on the couch, watching the same old television show or surfing the web to find something new and interesting? Put down that remote and step away from the keyboard. The Lifelong Scholar Society is where you need to be!
The Thursday Night Lecture Series gives you the satisfaction of stimulating the brain without the worry of attending a college course. Every other Thursday evening, you will have the opportunity to interact with accomplished Florida Institute of Technology professors and local experts of their respective fields. Plus, you'll get to know fellow members and guests.
Florida Tech’s Lifelong Scholar Society has moved online until it is deemed safe for us to meet in person again. We are using the online meeting website Zoom. It is super easy and you don’t have to be a computer whiz to join in the fun. You can participate via desktop, laptop, tablet, or simply listen on your phone.
Currently, there will be no charge for this pilot "members only" online version of the Lifelong Scholar Society. Join in, enjoy the lecture, and see your Lifelong friends online.
Thunderstorm Lightning of the Unusual Kind
Dr. Steven Lazarus is a Professor of Ocean Engineering and Marine Sciences. Dr. Lazarus's research interests are varied and include data assimilation, electrical phenomena such as gigantic jets, surface layer meteorology, and wind/wave interactions. He has authored or co-authored 30 peer-review articles and has had two dozen proposals funded totaling a little over $2 million. Over the past decade, he has reviewed over 30 articles or proposals and has served on both NASA and NSF panels. He has also graduated eight master's students, and more recently, two Ph.D. students. He is currently supervising a Ph.D. student who is funded under a NIST grant involving the impact of wind loading on residential structures. Dr. Lazarus is a PI on a SECOORA grant involving the installation and operation of a coastal (wind and wave) radar system here in east-central Florida. Presently, he is serving as an academic member representative for the University Center for Atmospheric Research (UCAR), a consortium that includes 120 North American universities with programs in meteorology, hydrology, oceanography, atmospheric chemistry, climate science, etc.
Description: While most folks are familiar with cloud-to-ground and intercloud lighting, there are a host of other lighting phenomena that exist that and referred to as transient luminous events (or TLEs). The subject of this talk focuses on one kind of TLE, particularly the gigantic jet, a relatively rare and spectacular form of upward propagating lightning that reaches up to the ionosphere, 100 km above the Earth’s surface. What causes a thunderstorm to send these bolts up instead of down? Why do they tend to occur more often in association with tropical disturbances? Why don’t we see more of them? Participants will experience these events as viewed from high-speed, low-light cameras and learn about their meteorology from weather balloons, satellite animations and radar observations.
