[1] Grazulis earned a bachelor's degree in meteorology from Florida State University (FSU) and was briefly a broadcaster, in part presenting the weather.
Grazulis' tornado database work was considered important enough that he was awarded five years of additional funding from the National Science Foundation.
[1] In the process, Grazulis traveled the country visiting dozens of libraries, museums, university archives, historical societies, and the like, to eventually chronicle 60,000 tornadoes, 50,000 of them included in a single 1,400-page book that is widely referenced.
In turn, proceeds of this book and of Tornado Project videos and posters were sufficiently robust to support an update that was published for the years 1992–1995.
[4] He collaborated with storm chaser Roy Britt to produce the popular Tornado Video Classics documentary series.
[7] Grazulis had long been interested in tornado simulators and included earlier laboratory studies in his TVC documentaries.
The new volumes will include updates on statistics, graphs, and charts, as well as analysis of trends in tornadic activity and examination of potential influence thereof by climate change.
[citation needed] Grazulis initially produced documentaries on the Earth sciences before focusing on tornadoes and publishing books.
