Abstract:

The rapidly developing storm of 28-30 November 1963 is selected to establish techniques for testing the reliability of various diagnostic procedures. The method of constructing isentropic trajectories is discussed and the results of applying these trajectories to determine average vertical motions and relative humidities are presented. These results which apply at the mid-time between the standard radiosonde releases permit comparisons to both the observed clouds and precipitation. Special intermediate soundings are available which provide a direct check on the advected moisture and an indirect check on the trajectories. Comparisons are also made with machine calculated instantaneous vertical motions. In general, it is found that the vertical motions derived from the isentropic trajectory method provide the greatest resolution and closest agreement with the reported clouds and precipitation.
