Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1918 edition. Excerpt: ...of very mild winters are much cloud, high humidity and rainfall, unsettled weather with much wind. Occasionally mild winters are, however, characterised by quiet, foggy weather, with much cloud and little rain. In mild winters the wind generally comes from the west. There is no regularity in the occurrence of mild winters, but they have been much more frequent in Berlin since 1862 than before. In the period 1909-10 to 1915-16, there were 7 winters, of which 5 were very mild more remarked upon. After very mild winters there is usually a cold snap in March or April, and a normal or warm summer. R. C. and 1 was mild. Hence the comparatively severe winter of 1916--17 was the 740. Noclurnal Cooling of the Lower Layers of the Almosphcre. H. Perrotin. (Comptes Rendus, 166. pp. 616-617, April 15, 1918.)---According to the equation commonly given in text-books of meteorology, the temperature 0 during the night obeys the law 9 = 60 + Ae--'/C-1, where it is supposed that temperature changes are due to radiation only. Here 90 is a fixed base tem _ perature, A a constant, 0' the so-called coefficient of radiation, c the specific heat of air at constant pressure, and 1 represents time. On applying this equation to observations made in different parts of the globe, a constant value of 0 has been found (about 0036), which is appreciably higher than the value of the coefficient as determined in the laboratory. According to observations made at Pare St. Maur, Paris, and at three levels (heights 128, 197, and 302 m.) on the Eiffel Tower, from 1890 to 1894, the coeflicient varies' from 0033 at the surface to 0022, 0018, and 0016 at the higher levels. It is concluded that the cooling of the lower layers is probably not produced like that of a solid...show more
