Presents an eighteen-level axisymmetric primitive equation tropical cyclone model incorporating the Arakawa-Schubert (1974) spectral cumulus parameterization.

A preliminary climatology of mesoscale convective complexes (MCCs), based on satellite data from two warm seasons, indicates that these systems frequently affect United States agricultural regions and it is hypothesized that MCCs produce a highly significant portion of the growing season precipitation over these areas.

The erosion and subsequent mixing to the environment of the updraft of mesoscale convective clouds is examined and modeled as a mechanism for the thermal modification of the cloud environment.

"Surface wind data from 20 Prototype Regional Observing and Forecasting Service (PROFS) surface mesonetwork stations have been analyzed for the month of July 1981 to determine characteristic flow patterns over northeast Colorado. Streamline analyses of the surface flow over this region have been prepared on an hourly basis."

Microwave brightness temperature data from the Nimbus 5 satellite have been analyzed, using threshold brightness temperatures, to yield tropical oceanic precipitation frequencies for several classes of rainfall rates during the season December 1972 to February 1973.

This study examines the sensitivity of horizontal heterogeneities of the soil moisture initialization (SMI) in the cloud-resolving grid of two real-data mesoscale convective system (MCS) simulations during their genesis phase.
