✦ Synopsis

Abstract

The diurnal and semi‐diurnal waves of barometric pressure are obtained for individual days. The diurnal wave, with a mean amplitude of from 0·6 to 0·8 mb., shows a standard departure from the mean of 0·25 mb., and, in consequence is sometimes absent. The semi‐diurnal wave, with a mean amplitude of 1·0 mb., shows a standard departure of only 0·1 mb., and the phase is very steady. The reality of these variations is supported by correlation between stations and with diurnal variations of temperature.
