Excerpt from Elementary MeteorologyIt should be noticed that the more important general conceptions, such as the arrangement of isobaric surfaces, or the vertical temperature gradient, are gradually introduced, at first in their simplest form, and later in greater complication. The all-important process of convection is illustrated in local examples, with particular definition of the conditions of its occurrence, in Chapter III, then in a larger way for the earth as a whole in Chapter VI, and, finally, the aid given to the process by the condensation of water vapor is 'added in Chapter IX. The explanation of the general circulation of the atmosphere by simple convection in Chapter VI is found to need a supple ment (the defiective force of the earth's rotation) at first unperceived in the deductive statement of the problem and thus a useful lesson is given in the importance of confirming deductive explanations by continually confronting their consequences with the facts of observation. This lesson is repeated in a somewhat different form in Chapter X. On perceiving the similarity in the arguments of these two chapters (section 230) much confidence may be placed in the amended convectional theory but another wholesome lesson is taught on discovering that our extra-tropical cyclones are not even yet certainly explained. A useful exercise in the suspension of judgment is here gained in holding the mind Open for further evidence before settling down upon a conviction as to the share that one process or another has in their origin.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
