WINCH, a cylindrical piece of timber, furnished with an axis, whose extremities rest in two channels placed horizontally or perpendicularly. It is turned about by means of an handle resembling that of a draw-well, grind-stone, &c. and is generally employed as a purchase, by which a rope may be more conveniently or more powerfully applied to any object, than when used singly, or without the assistance of mechanical powers.
WIND, vent, a stream or current of air which may be felt; and usually blows from one part of the horizon to its opposite part.
The horizon, besides being divided into 360 degrees, like all other circles, is by mariners supposed to be divided into four quadrants, called the north-east, north-west, south-east, and south-west quarters. Each of these quarters they divided into eight equal parts, called points, and each point into four equal parts, called quarter-points. So that the horizon is divided into 32 points, which are called rhumbs or winds; to each wind is assigned a name, which shews from what point of the horizon the wind blows. The points of north, south, east, and west, are called cardinal points and are at the distance of 90 degrees, or eight points from one another.
Winds are either constant or variable, general or particular. Constant winds are such as blow the same way, at least for one or more days; and variable winds are such as frequently shift within a day. A general or reigning wind is that which blows the same way, over a large tract of the earth, almost the whole year. A particular wind is what blows, in any place, sometimes one way, and sometimes another, indifferently. If the wind blows gently, it is called a breeze; if it blows harder, it is called a gale, or a stiff gale; and if it blows with violence, it is called a storm or hard gale[[58]].
The following observations on the wind have been made by skilful seamen: and particularly the great Dr. Halley.
1st. Between the limits of 60 degrees, namely, from 30° of north latitude to 30° of south latitude, there is a constant east wind throughout the year, blowing on the Atlantic and Pacific oceans; and this is called the trade-wind.
For as the sun, in moving from east to west, heats the air more immediately under him, and thereby expands it; the air to the eastward is constantly rushing towards the west to restore the equilibrium, or natural state of the atmosphere; and this occasions a perpetual east wind in those limits.
