The Relationship Between Horizontal Moisture Convergence and Severe Storm Occurrences
Abstract
An objective analysis of the wind and mixing ratio using three-hourly surface observations was used to obtain patterns of horizontal moisture convergence over the eastern two-thirds of the United States. Sixty-three segments of time periods during April and May 1970, were examined. All cases chosen had severe weather occurring during some portion of the entire period. A comparison was made between the fields of horizontal moisture convergence and reported severe weather occurrences. It was found that severe weather tends to develop at or closely after the time of strongest moisture convergence. Results of a quantitative study indicate that it may be beneficial to calculate horizontal moisture convergence on an hourly basis for use as a severe weather predictor.
