Le Climat de la France: Température, Pression, Vents

Abstract

THIS publication, dealing particularly with temperature, pressure, and winds, is rather a compilation than otherwise, free use being made of the original scientific discussions by M. Angot. Temperature observations made in France go back to the middle of the seventeenth century, but, as in other countries, the early observations were made with imperfect instruments, and the exposure was often bad, the results in consequence being unsatisfactory. There are only fourteen stations in France at which the observations cover a period of fifty years, from 1851—1900, but fairly long periods are given for fifty-eight stations which constitute the principal values dealt with. Mean temperature charts are given for each month, and there are also seasonal charts for winter, summer, and for the year. Diurnal range of temperature is also dealt with. Barometric pressure is treated in a very similar manner to the temperature, and mean pressure charts are given for all months and for the year. A chapter is devoted to the disturbances of the atmosphere, and a detailed description is given of the general movement of cyclonic and anticyclonic systems. Maps are given showing the prevailing winds and the resultants fpr the four seasons of the year. M. Bigourdan provides a good résumé of the climate of France in about 130 pages, and the information is expressed in a popular manner, although its scientific accuracy is all that could be wished. The numerous charts enable the reader to obtain the several meteorological factors for any part of France.
