The 30th parallel north is a latitude line that forms an angle of 30 degrees north of the earth's equatorial plane at a geographic latitude. It passes just one-third of the distance from the North Pole to the equator, passing through Africa, Asia, the Pacific, North America and the Atlantic Ocean. At this latitude, the solstice is 14 hours and 5 minutes, and the winter solstice is 10 hours and 13 minutes. Approximately the southern limit of the subtropical latitudes in the Northern Hemisphere, which means that most of the land on the 30th parallel north has a desert or steppe climate. Even near this parallel, if the area has a sufficient water source and a moist wind blows, it is often classified as subtropical. At this latitude, the meridian arc length fractionated by degrees, minutes, and seconds by the degree method corresponds to the following length. 1 degree 96.49 km (59.95 mi) 1 minute 1.61 km (1.00 mi) 1 second 26.80 m (87.93 ft)
