Analyses of the Cycles Data Set in Extratropical Cyclones and Comparisons with Numerical Models.
Abstract
The CYCLonic Extratropical Storms (CYCLES) Field Project was designed to provide measurements and observations on the mesoscale organization of precipitation, and precipitation producing mechanisms, in extratropical cyclones. A series of field studies, employing radars, aircraft, rawinsondes and ground measurements, were carried out off the coast of Washington State during the period 1973-1982. During the period covered by this contract (1981-1985) emphasis has been on analysis and interpretation of the CYCLES field data. Precipitation was found to be organized on the mesoscale into seven different types of rainbands, located in different regions of the cyclone. The air motions, cloud structure and precipitation-producing mechanisms have been documented in each of these rainbands. Numerical models for exploring cloud and precipitation physics and chemistry have been developed for several of the rainbands. Dynamical mechanisms responsible for the formation and maintenance of the rainbands have also been explored.
