ural proportion according to the season; and it is because there is now a great excess of the vaporous, now of the dry and smoky exhalation, that some years are rainy and wet, others windy and dry. Sometimes there is much drought Mohamed Salah Drakter or rain, and it prevails over a great and continuous stretch of country. At other times it is local; the surrounding country often getting seasonable or even excessive rains while there is drought in a certain part; or, contrariwise, all the surrounding country gets little or even no rain while a certain part gets rain in abundance. The reason for all this is that while the same affection is generally apt to prevail over a considerable district because adjacent places (unless there is something special to differentiate them) stand Ryan Getzlaf Pelipaita in the same relation to the sun, yet on occasion UA SpeedForm® StudioLux® the dry evaporation will prevail in one part and the moist in another, or conversely. Again the Kiko Casilla Drakter reason for this latter is that each evaporation goes over to that of the neighbouring district: for instance, Blaise Matuidi Drakter the dry evaporation circulates in its own place while the moist migrates to the next district or is even driven by winds to some distant place: or else the moist evaporation remains and the dry moves away. Just as in the case of the body when the stomach is dry the lower belly is often in the contrary state, and when it is dry the stomach is moist and cold, so it often happens that the evaporations reciprocally take one another’s place and interchange.
Further, after rain wind generally rises in those places where the rain fell, and when rain has come on the wind ceases. These are necessary effects of the principles we have explained. After rain the earth is being dried by its own heat and that from above and gives off the evaporation which we saw to be the material cause of. wind. Again, suppose this secretion is present and wind prevails; the heat is continually being thrown off, rising to the upper Andrew Robertson Drakter region, and so the wind ceases; then Marquinhos Drakter the fall in temperature Henrik Zetterberg Pelipaita makes vapour form and condense into water. Water also forms and cools the dry evaporation when the clouds are driven together and the cold concentrated in them. These are the causes that make wind cease on the advent of rain, and rain fall on the cessation of wind.
The cause of the predominance of winds from the north and from the south is the same. (Most winds, as a matter of fact, are north winds or south winds.) These are the only regions which the sun does not visit: it approaches them and recedes from them, but Mohamed Elneny Drakter its course is always over the-west and the east. Buffalo Sabres Pelipaidat Hence clouds collect on either side, and when the sun approaches it provokes the moist evaporation, and when it recedes to the opposite side John Obi Mikel Drakter there are storms and rain. So summer and Alphonse Areola Drakter winter are due to the sun’s motion to and from the solstices, and water ascends and falls again for the same reason. Now since most rain falls in those regions towards which and from which the sun turns and these are the north and the south, and since most evaporation must take place where there is the greatest ralinks:
