Welcome to Joe Zagrodnik's webpage.

Research interests

I work with Lynn McMurdie and Robert A. Houze in the Mesoscale Group at the University of Washington. My PhD research uses surface, radar, and aircraft observations from field campaigns to infer the physical processes that produce rain and snowfall over mountainous regions. I study a range of scales from the large-scale atmospheric dynamics governing frontal cyclones, mesoscale features such as rainbands and convection, and liquid/ice precipitation microphysics.

Specific topics of interest include:

  • Stratiform precipitation processes in cyclones passing over coastal mountain ranges
  • Down-valley flow and its effects on upstream precipitation patterns and microphysics
  • Precipitating cloud structure and microphysical characteristics of precipitation on the high terrain and lee side of the Olympic Mountains
