Abstract

The evaluation of microphysical parameterization processes for their use in the high-resolution MM5 simulations of Hurricanes Bonnie and Floyd is discussed. The observation used in the intercomparisons are tail-mounted vertical incidence Doppler radar data, microphysics probe data, and flight-level data. Above 9 km the mode of vertical motion is upward, reflecting the loss of hydrometeors and reduction in water loading in the upper levels. The eyewall contoured frequency by altitude diagrams (CFAD) shows the high reflectivity bias, as values reaches 60 dBZ for the top 1% of points and the mode in the lowest 3 km is around 40-45 dBZ for the eyewall.
