UTM zones are numbered 1 through 60, starting at the international date line, longitude 180Â°, and proceeding east. Zone 1 extends from 180Â° W to 174Â° W and is centered on 177Â° W. Each zone is divided into horizontal bands spanning 8 degrees of latitude.
Middle latitudes. The middle latitudes are between 23Â°26'22 North and 66Â°33'39 North, and between 23Â°26'22. South and 66Â°33'39. South latitude, or, the Earth's temperate zones between the tropics and the Arctic and Antarctic polar regions. The prevailing winds in the middle latitudes are often very strong. These parts of the world also see a wide variety of fast-changing weather as cold air masses from the poles and warm air masses from the tropics push up and down over them, sometimes alternating within hours of each other, especially in the roaring forties (between 40 and 50 degrees latitude in both hemispheres).
