• Date: 8/1/1983
• Weather Modification - Doc Type: Report

Observational and modeling studies of convective precipitation
systems from the less strongly forced tropical systems to the mid-
latitude squall line show the need for mesoscale data sets and
objective analysis tools to improve our understanding of the natural
variability of convective precipitation mechanisms. The complex
nature of interactions from the boundary layer controls of moist
static energy to the mid- and upper-tropospheric momentum transfer
and divergence impacts on vertical motion fields require mesoscale
rawinsonde information. The following sections describe the type of
data, their analysis and quality control, physical characteristics of
convective systems and their natural variability, and develop a
conceptual and composit model of their structure which may be used to
better understand the natural variations in convective precipitation.
