The laws that govern the transmission of large\u003cbr\u003ebodies of air from one part of the oceanic surface to another, either in\u003cbr\u003ea state of rapid rotation or presenting a more or less rectilineal\u003cbr\u003edirection, must at all times form an important matter of inquiry, and\u003cbr\u003ebear very materially on the successful prosecution of the occupation of\u003cbr\u003ethe voyager.\u003cbr\u003e\u003cbr\u003eIn order to place the subjects above alluded to in such a point of view\u003cbr\u003ethat the connexion between them may be readily seen, it will be\u003cbr\u003eimportant to notice the principal phænomena presented by each. Without\u003cbr\u003egoing over the ground so well occupied by those able writers on the\u003cbr\u003esubject of storms--Redfield, Reid, Piddington, and Thom--it will be\u003cbr\u003equite sufficient for our present purpose simply to notice the essential\u003cbr\u003ephænomena of revolving storms as manifested by the barometer and vane.\u003cbr\u003eThe usual indications of a storm in connexion with these instruments are\u003cbr\u003ethe _falling_ of the barometer and the _freshening_ of the wind, and it\u003cbr\u003eis generally considered that a _rapid_ fall of the mercury in the\u003cbr\u003ehurricane regions invariably precedes the setting in of a storm.\u003cbr\u003e\u003cbr\u003eThere are three classes of phænomena that present themselves to an\u003cbr\u003eobserver, according as he is situated _on_ the line or axis of\u003cbr\u003etranslation, or _in_ either the right or left hand semicircle of the\u003cbr\u003estorm. These will be rendered very apparent by a little attention to the\u003cbr\u003eannexed engraving, fig. 1.","brand":"SAP","offers":[{"title":"Default Title","offer_id":47180437979376,"sku":"2940013221086","price":0.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940013221086_p0.jpg?v=1763578463","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940013221086","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
