		The vertical structure of clouds and precipitation in the Tropics, as  perceived by cloud and precipitation radars (8.66-mm K-band and 5.4 cm  C-band, respectively) is evaluated. The data originates from several  oceanic field experiments held within convective regimes, but at different tropical locations: 10N, 95W (Eastern Pacific Investigation of Climate,  Oct 2001), the Bay of Bengal (Joint Air-Sea Monsoon Interaction Experiment,  May 1999), 5N-15N at 95W and 110W (Pan-American Climate Studies, 7 days  Oct-Nov 2000, cloud radar only), and 125W, 6-8N (Tropical Eastern Pacific Process  Study, August 1997, precip radar only). The relationship of the cloud-radar-perceived  vertical structure to levels of enhanced stability and high wind shear as derived  from sounding data will be explored, as well as to the divergence profile inferred  from the precipitation radar data, and to surface-based measurements of rainfall.  A buoyancy-sorting model (Raymond and Blyth, 1992) will be utilized to examine a connection of the cloudiness vertical distribution to preferred  levels for convective outflow.
