Professional InterestsJun Zhang's main research interests are hurricane boundary layer structure and dynamics, turbulence observations, air-sea interaction, numerical modeling and physical parameterizations. He has recently studied turbulent fluxes in the hurricane boundary layer using research aircraft and portable wind tower observations, dissipative heating in the surface layer both over the ocean and land, hurricane boundary layer height using dropsonde data, air-sea thermodynamic exchange using buoy observations, vertical and horizontal turbulence mixing processes in the low-level troposphere of intense hurricane eyewall, and evaluation and improvement of the planetary boundary layer (PBL) schemes used in the WRF and HWRF models simulating hurricanes.
