Abstract
LONDON. Royal Meteorological Society, April 17.—The late W. H. Dines and L. H. G. Dines: Monthly mean values of radiation from various parts of the sky at Benson, Oxfordshire. Records for the five years 1922–1926 are given. The radiation is dealt with under two heads:—(1) Luminous rays; (2) dark heat rays of wave-length exceeding about 2 >j.; each is measured under conditions of (1) clear skies, (2) completely overcast skies.—L. H. G. Dines: An analysis of the changes of temperature with height in the stratosphere over the British Isles. The average temperature distribution in the stratosphere over the British Isles consists of a pronounced inversion of 3° C. at the bottom, followed by a lapse of about 0-5° 0. per km. from (He + 3) km. upwards to at least (Hc+8). There is no significant connexion between the magnitude of the inversion and either the lapse rate just below it, or the temperature in the troposphere in the layer 3J to 7J km. Such evidence as is available is against the existence of a diurnal variation of temperature in the stratosphere.—H. A. Hunt:—A basis for seasonal forecasting in Australia. A fairly definite four-year cycle is indicated, consisting of two dry years followed by two wet years, and requiring two years to be allotted to the drying and heating phase and two to the wetting and cooling. The four-year period in the rainfall is also fairly well marked in the percentage of the continental area over which the rainfall is above the average each year.
