Biography

Steve Stegall received his undergraduate degrees in meteorology and applied math from Metro State College of Denver and his Master of Science in atmospheric science from the University of Arizona. He recently completed his Ph.D. from North Carolina A & T State University in atmospheric science. For his Dissertation he analyzed surface winds in the Chukchi/Beaufort Seas and North Slope Alaska region and created a 31-year surface wind climatology as well as analysis of the Chukchi–Beaufort High-Resolution Atmospheric Reanalysis (CBHAR) dataset establishing an inverse correlation and relationship between wind speed and SST in the Chukchi/Beaufort Seas region due to strong cold air advection from wind flow off ice onto the warmer ocean water and cloud/radiation properties.

Steve Stegall joined the NCICS team in May 2014 as a Post Doctoral Research Scholar. He will be collaborating in assessment on the utility of HIRS 2-m air temperature on NCEI’s global temperature product as well as providing further analysis of CMIP5 temperature and precipitation trends.

He also enjoys hiking, traveling and cooking as hobbies.
