  11. PR, RI and SS comparisons (Divergence and RH)

  12. Hovmoller (WS10, SLP, Rainrate, and TPW) SS RI PR SS RI PR

  13. Hovmoller (T10, q10, delT, and delQ) SS RI PR SS RI PR

  14. Hovmoller (SHFX and LHFX) SS RI PR • In terms of the azimuthally averaged fields, only vertical velocity and divergence show strong signal during RI compared to that during PR and SS; • The Hovmoller diagrams of the azimuthally averaged surface layer fields are very interesting. It appears that the dry and cool air near the surface was transported into the core during pre-RI. The air-sea contrast of temperature and humidity are very large during pre-RI, which induced large enthalpy fluxes. It is hypothesized that the accumulated surface enthalpy fluxes during pre-RI stage boost the RI.

  15. ZACHARY GRUSKINAOML / NOAA & UNIV. OF WISCONSIN

  16. Zachary Gruskin, Jun Zhang, Frank Marks, and Gregory Tripoli Boundary layer flight level data from Allen (1980), Hugo (1989), Isabel (2003), and Fabian (2003) is being analyzed. High resolution runs of the UW-NMS will be used to study structures in the boundary layer and their evolution. The structure and evolution of boundary layer vorticity filaments and their impact on hurricane inner-corestructure and intensity Hurricane Allen data at ~500 m f CoUW (m2 s-2) Frequency (Hz)
