The latitude of the circle is approximately the angle between the Equator and the circle, with the angle's vertex at Earth's centre. The Equator is at 0°, and the North Pole and South Pole are at 90° north and 90° south, respectively. The Equator is the longest circle of latitude and is the only circle of latitude which also is a great circle.
The 63rd parallel south is a circle of latitude that is 63 degrees south of the Earth's equatorial plane. It crosses the Southern Ocean and Antarctica . At this latitude the sun is visible for 20 hours, 19 minutes during the December solstice and 4 hours, 42 minutes during the June solstice .
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
The declination of the Sun, δ ☉, is the angle between the rays of the Sun and the plane of the Earth's equator. The Earth's axial tilt (called the obliquity of the ecliptic by astronomers) is the angle between the Earth's axis and a line perpendicular to the Earth's orbit. The Earth's axial tilt changes slowly over thousands of years but its ...
The 30th parallel south is a circle of latitude that is 30 degrees south of the Earth's equator.It stands one-third of the way between the equator and the South Pole and crosses Africa, the Indian Ocean, Australia, the Pacific Ocean, South America and the Atlantic Ocean.
The 23rd parallel north is a circle of latitude that is 23 degrees north of the Earth's equatorial plane, about 50 kilometres (31 mi) south of the Tropic of Cancer. It crosses Africa , Asia , the Indian Ocean , the Pacific Ocean , North America , the Caribbean , and the Atlantic Ocean .
The equator is the circle of latitude that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude , about 40,075 km (24,901 mi) in circumference, halfway between the North and South poles. [ 1 ]
In the context of physics, zonal flow connotes a tendency of flux to conform to a pattern parallel to the equator of a sphere. In meteorological term regarding atmospheric circulation , zonal flow brings a temperature contrast along the Earth's longitude.
