Page 217 - Rainfall is not essential to the formation of areas of low barometer, and is not the principal cause of their formation or of their progressive motion.
Page 217 - The greater rarefaction of the atmosphere at some times than at others, without doubt, has considerable effect upon the barometer ; but the theory which attributes the whole of the barometrical oscillations to the rarefaction of the atmosphere produced by the condensation of vapor in the formation of clouds and rain, cannot be maintained...
Page 150 - In whatever direction a body moves on the surface of the earth, there is a force arising from the earth's rotation which deflects it to the right in the northern hemisphere, but to the left in the southern hemisphere.
Page 14 - ... 7090 Lignite occurs in the Cretaceous and early Cenozoic of the Rocky Mountain States, in the Dakotas, and on the Pacific Coast. In Germany, where it occurs in beds up to 300 feet thick, it is a highly valuable fuel resource. Cypress and sequoia are important ingredients in these German coals. * A British thermal unit is the heat required to raise 1 pound of water from 62° F to 63° F, 252 calories. Subbituminous Class. The subbituminous class of coals comprises those in the range between lignitic...
Page 14 - ... the scale of an instrument; also of correcting or determining the error of an existing scale, or of evaluating one quantity in terms of readings of another.
Page 238 - The campaign of extending the temperature observations into the higher levels is going on in different parts of the world, but definitive results have not been reached. There is no very general and fixed system of temperature values to be expected, because the incessant circulation, due to the annual change in declination of the sun, prevents the atmosphere from settling down into a simple thermal equilibrium.
Page 370 - The so-called isothermal layer from 11,000 to 38,000 meters is merely that part of the atmosphere where the surviving solar radiation nearly balances the terrestrial radiation. Above 38,000 meters is a region of very powerful absorption of the solar radiation, in which the energy of the short waves of the solar spectrum, A.
Page 363 - ... adopted will greatly facilitate the pursuit of such researches by many students. The practical side of the matter consists in the development of the branch of Meteorology and Solar Physics which will culminate in the ability to predict the seasonal climatic conditions likely to prevail during the coming year in the several large agricultural regions of the earth. The extent and scope of these subjects are so great that the co-operation of many institutions and national offices will be essential...
Page 288 - Bigelow reaches the same ratio in another way and finds that 'the isothermal region radiates 2.11 times as much heat as does the convectional region'.
Page 370 - A. = 0'00/t, to 0'40/t are (sic) absorbed, the energy being used in heating this stratum through about 208 degrees. This is the true albedo of the earth's atmosphere, and it amounts to nearly one-half of the total solar radiation falling on the earth's outer stratum of atmosphere.
