| description abstract | The buoyancy equation is integrated to find the downward speed of a parcel of air that becomes cooler than its environment and sinks to the ground, such as a downdraft in a thunderstorm. This downdraft speed is related to a positive energy area on a thermodynamic diagram. From a sample of one hundred soundings taken just prior to thunderstorm occurrences a correlation coefficient of 0.50 is obtained for the computed downdraft and measured wind gusts. Taking the upper wind speed into account fails to improve significantly the correlation coefficient. A correlation coefficient of only 0.22 is obtained for the direction of the surface wind gust and the wind direction in the 700?500-mb. layer. | |
