Abstract
LONDON. Royal Meteorological Society, Dec. 16.—W. C. Kaye and C. S. Durst: Some examples of the development of depressions which affect the Atlantic. Three typical cases show examples of: (1) a polar depression being intensified by the introduction of warm air from the Gulf of Mexico; (2) the formation of a family of depressions between Pacific maritime polar air and warm Gulf air; (3) the formation of depressions on a quasi-stationary front. A majority of the families of depressions which cross the Atlantic originate in one or other of these ways.—Alfred A. Barnes: (1) Rain-gaugings near Belper and Duffield, Derbyshire. A complete analysis of the yearly readings taken at 19 rain-gauges at the southern end of the Pennine Chain during a period of 66 years from 1865 to 1930 inclusive.—(2) Rainfall reviewed: a common long-average period for each country of the British Isles. A new survey during a period of 68 years from 1863 to 1930 inclusive.—W. H. Pick: Visibility with saturated air. The horizontal visibilities at Worthy Down and Felixstowe, over a period of four years, whenever the air was saturated are examined. All degrees of visibility (except the very best) were well represented. A large percentage of the cases of saturated air were unaccompanied by either fog or mist. The effect of wind force upon the visibility accompanying saturated air is also examined.
