THE VERTICAL DISTRIBUTION OF OZONE OVER TALLAHASSEE, FLORIDA.
Abstract
158 Regener chemiluminescent ozonesondes were launched from Tallahassee, Florida, (30.5 as part of a three-year synoptic sounding program for the investigation of the vertical distribution of ozone over North America. In general, there was a single maximum of ozone density located near 23 km above Tallahassee throughout the year. The increase to this maximum began at the tropical tropopause and at least 80 per cent of the total amount of ozone was located above this tropopause. Relative maxima below this level occurred during the first half of the year and their appearance could be related to the presence of the subtropical jet stream south of Tallahassee and to the horizontal movement of 'ozone clouds' within the layer between the tropical and subtropical tropopauses. The formation process of these secondary maxima was investigated by constructing isentropic trajectories to trace the movements of the maxima. An inquiry into the cause of a 40 per cent variation of total ozone during a 10-day period indicated that it resulted primarily from horizontal and vertical motions between 16 and 24 km and secondarily from horizontal advection between 12 and 16 km. In both layers these processes were found to be under the control of middle latitude circulation systems. (Author)
