Abstract: A diverse set of mesoscale observations collected in the National Hail Research Experiment in connection with an evolving Colorado hailstorm is analyzed to determine the kinematic and thermodynamic structure of the near ...

Abstract: Guidelines followed in designing and operating a special mesoscale rawinsonde network are discussed. Objective data reduction and analysis techniques are developed and applied to the wind, temperature and moisture data ...

Abstract: The precipitation efficiency (the ratio of surface rainfall to water vapor inflow) of a small sample of thunderstorms observed in the Cooperative Convective Precipitation Experiment is calculated using surface and cloud-base ...

Abstract: With an attainable height resolution of no better than ±10 m from individual soundings, direct analysis of geopotential height gradient from mesoscale rawinsonde ascents could not be expected to produce reliable results. ...

Abstract: Observations from aircraft, Doppler radars, surface mesonetwork, upper air network and surveillance radar are used to describe the structure and evolution of a large rain and hailstorm that occurred on 22 June 1976 in ...

Abstract: A case study is presented of a persistent thunderstorm of moderate intensity which occurred in northeast Colorado, and which produced a light hailfall at the ground. The storm was intensively monitored by aircraft, radar, ...

Abstract: Data from five Doppler radars, the surface mesonet, aircraft, and rawinsondes from the Cooperative Convective Precipitation Experiment (CCOPE) are used to document the structure and evolution of a squall line with unusually ...

Abstract: Photographs of some variform cloud features observed in the inflow sector of an intense thunderstorm that occurred in southeastern Montana on 11 July 1981 are described. Associated meteorological conditions are interpreted ...

Abstract: Objective numerical techniques are applied in analyzing constant altitude aircraft measurements obtained from coordinated research flights in thunderstorm inflow regions. The approach combines meteorological and flight ...

Abstract: A detailed analysis is made of the environmental conditions existing on each of the declared hail days during the randomized seeding experiment. From the many soundings available each day, the one most representative of ...
