Consequently, the equator has a rather stable daytime temperature throughout the year. On the equinoxes (approximately March 20 and September 23) the subsolar point crosses Earth's equator at a shallow angle, sunlight shines perpendicular to Earth's axis of rotation, and all latitudes have nearly a 12-hour day and 12-hour night.
The thermal equator (also known as "the heat equator") is a belt encircling Earth, defined by the set of locations having the highest mean annual temperature at each longitude around the globe.
Therefore, lesser tilt means a wider annual temperature gap between equator and poles, while greater tilt means a smaller annual temperature gap between equator and poles. [4] (At an extreme tilt, such as that of Uranus, the poles can receive similar annual surface insolation to the equator.) In particular, at Earth temperatures, and all else ...
Everywhere around the world during the equinoxes (March 20/21 and September 22/23) except for the poles, the sun rises due east and sets due west. In the Northern Hemisphere, the equinox sun peaks in the southern half (about halfway up from the horizon at mid latitude) of the sky, while in the Southern Hemisphere, that sun peaks in the northern ...
The 45th parallel north is often called the halfway point between the equator and the North Pole, but the true halfway point is 16.0 km (9.9 mi) north of it (approximately between 45°08'36" and 45°08'37") because Earth is an oblate spheroid; that is, it bulges at the equator and is flattened at the poles.

In meteorological term regarding atmospheric circulation, zonal flow brings a temperature contrast along the Earth's longitude. Extratropical cyclones in zonal flows tend to be weaker, moving faster and producing relatively little impact on local weather. Extratropical cyclones in meridional flows tend to be stronger and move slower.
Most regions on the Tropic of Cancer experience two distinct seasons: an extremely hot summer with temperatures often reaching 45 °C (113 °F) and a warm winter with maxima around 22 °C (72 °F). Much land on or near the Tropic of Cancer is part of the Sahara Desert , while to the east, the climate is torrid monsoonal with a short wet season ...
The 60th parallel north is a circle of latitude that is 60 degrees north of Earth's equator. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean . Although it lies approximately twice as far away from the Equator as from the North Pole , the 60th parallel is half as long as the Equator line, due to the cosine ...
