Not illustrated. 1872 edition. Excerpt: ...to the more or less constant directions in which winds blow, they may be classed as regular, periodical, and variable winds. i. Regular winds are those which blow all the year through in a virtually constant direction. These winds, which are also known as the trade winds, are uninterruptedly observed far from the land in equatorial regions, blowing from the north-east to the south-west in the northern hemisphere, and from the south-east to the northwest in the southern hemisphere. They prevail on the two sides of the equator as far as 300 of latitude, and they blow in the same direction as the apparent motion of the sun, that is, from east to west. The air above the equator being gradually heated, rises as the sun passes round from east to west, and its place is supplied by the colder air from the north or south. The direction of the wind, however, is modified by this fact; that the velocity which this colder air has derived from the rotation of the earth, namely, the velocity of the surface of the earth at the point from which it started, is less than the velocity of the surface of the earth at the point at which it has now arrived; hence the currents acquire, in reference to the equator, the constant direction which constitutes the trade winds. ii. Periodical winds are those which blow regularly in the same direction at the same seasons, and at the same hours of the day; the monsoon, simoom, and the land and sea breeze are examples of this class. The name monsoon is given to winds which blow for six months in one direction, and for six months in another. They are principally observed in the Red Sea and in the Arabian Gulf, in the Bay of Bengal and in the Chinese Sea. These winds blow towards the continents in summer, and in a contrary direction...
