Abstract: A simple numerical model is formulated for a mixed-phase cold cloud which simulates the interaction among the updraft, crystal growth, droplet growth or evaporation, and ice crystal concentration. The model accounts for ...

Abstract: Mesoscale lows or pressure troughs have been observed downwind of many mid-latitude cumulonimbus cloud systems, especially those that subsequently produce severe weather such as tornadoes, large hail, or damaging wind ...

Abstract: Synoptic-scale mass and moisture budgets are objectively computed by kinematic techniques and compared to the mass and moisture budgets of a tornado-producing Oklahoma squall line. The rate of consumption of water vapor ...

Abstract: An orographic cloud seeding experiment conducted in the vicinity of Climax, Colo., has been continued for five additional wintertime periods from 1965?70. A comparison of this new independent information is made with ...

Abstract: The nature of precipitation changes resulting from seeding cold orographic clouds is examined by separating the observed total precipitation change into duration and intensity change components. The total precipitation ...

Abstract: It has been frequently observed that thunderstorms which interact with a warm front, or an old thunder-storm outflow boundary, are likely to increase in severity and become tornadic. The physical mechanisms responsible for ...

Abstract: This study is concerned with the elevation and spatial variation effects of wintertime orographic cloud seeding over an area encompassing Fremont, Hoosier and Vail mountain passes in the central Colorado mountains during ...

Abstract: Correction to Volume 104, Issue 11, Article 1408.

Abstract: Non-iterative methods for computing isobaric wet-bulb temperature and the temperature at the lifted sublimation level are presented. These quantities are then computed by these direct techniques and compared to values ...
