John A. Knaff


I earned a B.S. in Meteorology (1989) from Texas A&M University, and a MS (1992) and PhD (1997) in Atmospheric Science from Colorado State University. I was briefly a post-doctoral researcher in the Department of Atmospheric Science at Colorado State University (1997). Following that appointment, I was a post-doctoral Fellow at the Cooperative Institute for Research in the Atmosphere at Colorado State University (1997-1999) where he was also employed as a Research Scientist position (1999-2006). I then joined NOAA in 2006 as a Meteorologist in the NESDIS Regional and Mesoscale Meteorology Branch located in Fort Collins, Colorado.

As a student, I concentrated on topics related to tropical climate variability including El Nino/Southern Oscillation, monsoons, tropical cyclones and large-scale Atlantic climatology. The focus of my more recent studies, including his postdoctoral work, has been on observational aspects of hurricane structure and intensity variations and prediction. Much of that work has led to the development of forecast applications that have been transferred to operations at the NESDIS, the National Hurricane Center, the Joint Typhoon Warning Center, and tropical cyclone warning centers worldwide. These efforts have led to many awards. In 2004, he received the NOAA David Johnson Award for basic research for improving the understanding of tropical phenomenon and predicting tropical cyclone intensity, accompanied by exemplary transfer of the results into operational products. He has also been awarded Department of Commerce Bronze Medals in 2007, 2010, and 2012 and was a member of a team that received the Colorado Governor's Award for High Impact Research in 2012.

Current research includes the utilization of satellite and other observations to improve scientific understanding, diagnosis and forecasting capabilities of tropical cyclone genesis and structure change, the development and documentation of operational tropical cyclone forecasting techniques, and the transfer of such techniques to the operational setting. Since 1991, I have published more than 70 articles on tropical cyclones, mesoscale meteorology and tropical climatology in the refereed literature.
