Abstract
LONDON. Royal Meteorological Society, Juno 17.—S. Chapman: A theory of upper-atmospheric ozone. The paper consists of a discussion of the daily and annual variations of the ozone content of the atmosphere in any latitude up to about 50°. The ozone is treated as if it were uniformly spread through a layer of air 10 km. thick, having the same density as the air at the level of maximum ozone density. Convection and diffusion of ozone are neglected. The thermal decomposition of ozone (203=302) is discussed, and estimated to be negligible, except possibly in connexion with an eleven-year (sunspot) variation of ozone.—C. K. M. Douglas: On the relation between temperature and pressure in the troposphere. It is shown that the high correlation coefficients between pressure and temperature high up in the troposphere are closely related to the constancy of the lapse-rate of temperature. The correlations between the mean temperature of the column up to 9 km. and the temperatures at 3 and 6 km. are very high. Some factors tending to produce a constant lapse-rate are discussed. Groups of extreme cases show that when the barometer at sea level is very low or very high the troposphere contributes about half the deviation from the mean. Both cyclones and anticyclones can be grouped into systems largely confined to the troposphere, and systems extending to the stratosphere. The argument in favour of an advectional theory is developed.
