Abstract : The origin of air in the vicinity of a squall line that formed at 0600 GMT on November 16, 1960 was investigated in this study. The air was identified by values of potential vorticity and the conservative nature of this property was studied. High values of potential vorticity existed in the stratosphere while much smaller ones were typical of the troposphere. The source region of this air was determined by 12-hour air parcel trajectories. This study was conducted on a surface of constant potential temperature (isentropic surface) that sloped from the lower stratosphere over 16,000 feet into the troposphere. The potential temperature (O) surface equal to 315K was used throughout this study.
