Abstract
While there is a net production of ozone during electrical discharges in a thunder cloud the surface ozone recorder often registered a decrease in surface ozone concentration This decrease coincided with updraughts generated during the formation of a thunderstorm Similar sharp increases in ozone were observed with downdraughts In cases of lightning without the development of a thunderstorm over the station an increase in ozone density was observed just after the first lightning dischargeApart from the fluctuations associated with thunderstorms in summer sharp fluctuations in density were also noticed during winter in the mornings Abrupt falls in ozone occur with the formation of a stable layer near the ground at night and a sudden surge after the breaking up of the layers in the morning The changes in ozone are however much more pronounced than those in temperature and wind and this striking correlation between surface ozone surface air temperature and wind provides a unique tool for the study of lowlevel temperature inversions their establishment and destruction
