The four cardinal directions, or cardinal points, are the four main compass directions: north, south, east, and west, commonly denoted by their initials N, S, E, and W respectively. Relative to north, the directions east, south, and west are at 90 degree intervals in the clockwise direction. The ordinal directions (also called the intercardinal ...
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
Classical compass winds. The Tower of the Winds in Athens, partly reconstructed, in 1762. In the ancient Mediterranean world, the classical compass winds were names for the points of geographic direction and orientation, in association with the winds as conceived of by the ancient Greeks and Romans. Ancient wind roses typically had twelve winds ...
Wind direction is generally reported by the direction from which the wind originates. For example, a north or northerly wind blows from the north to the south; [ 1] the exceptions are onshore winds (blowing onto the shore from the water) and offshore winds (blowing off the shore to the water). Wind direction is usually reported in cardinal (or ...
A compass rose, sometimes called a wind rose, rose of the winds or compass star, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions ( north, east, south, and west) and their intermediate points. It is also the term for the graduated markings found on the traditional magnetic ...
North corresponds to 0°, so east is 90°, south is 180° and west is 270°. The history of the compass started more than 2000 years ago during the Han dynasty (202 BC – 220 AD). The first compasses were made of lodestone, a naturally magnetized stone of iron, in Han dynasty China. [ 1][ 2] It was called the "South Pointing Fish" and was used ...
The drift angle (shaded red) is due to the wind velocity (W/V, in green). In navigation, the heading of a vessel or aircraft is the compass direction in which the craft's bow or nose is pointed. Note that the heading may not necessarily be the direction that the vehicle actually travels, which is known as its course or track.
The Azure Dragon of the East represents Wood, the Vermilion Bird of the South represents Fire, the White Tiger of the West represents Metal, and the Black Tortoise (or Black Warrior) of the North represents Water. In this system, the fifth principle Earth is represented by the Yellow Dragon of the Center. [8]
