Air Ministry: Meteorological Office The Observatories' Year Book, 1922

Abstract

THE elements dealt with in the volume are barometric pressure, air temperature, humidity, rainfall, sunshine, wind velocity and direction, cloud and general weather. Records are tabulated for each hour. Details are given of the exposure and surroundings of the different instruments, and photographs show generally the position of the instruments. The work consists mostly of tabular results closely printed. Much information is afforded for minute study on various subjects of meteorological importance. At Eskdalemuir the diurnal variation in the components of magnetic force on quiet and disturbed days is given. The variation of the several components is shown by diagram for the year and for the several seasons, and average results are given for the years 1911–1921; special attention is also given to seismology. At Valencia the outstanding features for 1922 are said to be the cold weather of April, the prolonged low temperature, practically continuous from the middle of June to the beginning of November, and the small rainfall of October and November. At each of the four observatories (omitting Benson) the highest temperature during the year occurred at the end of May, and the minimum about the middle of January; at Kew the minimum reading was repeated on April 2, the highest and lowest readings occurring within 52 days of each other. The largest hourly measurement of rain at Aberdeen, Eskdalemuir, and Kew occurs in day hours between 8 A.M. and 5 P.M.; at Valencia it occurs between 1 and 2 A.M. The smallest hourly measurements occur between 7 A.M. and i P.M., except at Eskdalemuir, where it occurs from 8 to 9 P.M.
