Total ozone and vertical ozone profile were measured by Brewer ozone spectrophotometer and ozonesondes, respectively. The detailed latitudinal distribution of total ozone amount and height-latitude distributions of ozone concentration, temperature and wind at 5-degree latitude intervals from the equatorial region to the Antarctic region were observed. From the ozonesonde observations, the injection of ozone from the stratosphere to the troposphere through the tropopause gap was deduced. The decreased ozone concentration in the lower stratosphere, similar to as same as the Antarctic ozone hole, was observed south of 60°S. It is possible that this phenomenon was caused by transport of ozone-poor air (a 'dilution effect') following the spring time ozone hole.}, pages = {1--11}, title = {RESULTS OF OZONE OBSERVATION FROM THE EQUATORIAL REGION TO ANTARCTICA IN 1987}, volume = {4}, year = {1991} }
