Here, the CM1 model is used to simulate intense tropical cyclones in an idealized framework, with horizontal grid spacing as fine as 62 meters. At this grid spacing, the scales of the vortices (believed to be ~500-1500 m) are well resolved. The frequency and spatial distribution of these extreme updrafts are investigated. By tracking individual features in space and time, the characteristic structure and evolution is examined. It is currently unknown whether dropsonde observations represent quasi-vertical profiles through the features, or if instead the sondes are horizontally advected through the features. Simulated dropsonde trajectories are used to answer this question, and to aid in the interpretation of the observed kinematic and thermodynamic profiles. To gain insight into the origin and dynamics of the updrafts/vortices, vorticity budgets are examined. Finally, simulations where the grid spacing is systematically varied from 1 km to 62 m are used to determine the sensitivity of vertical velocity and its probability distribution to resolution.
