Imagine the world as a three-dimensional sphere with latitude lines running west to east. Along the equator, the hemispheres of the Earth are separated. From the equator to the North Pole, latitude is measured in degrees ranging from 0 to 90, and from −90 to the South Pole. The tropic of Cancer, the tropic of Capricorn, the Arctic circle, and the Antarctic circle are additional latitude lines. Today in this article you will learn about the effects of latitude on climate along with many other things. So, continue reading the article to know how ranges of latitude cause differences in temperature. 

1. What Factors are affecting Climate?

The ancient Greek philosopher Aristotle is credited with being the first to introduce the concept of climate zones. The most influential factors influencing climate are latitude, ocean currents, wind and mass, elevation, relief, and proximity.

Both north and south of the equator, lines of latitude run in either direction from 0° to 90°. In climate analysis, five key lines of latitude are employed. The equator is both the hottest part of the earth and the dividing line between all other latitudes. 23½° to the north of the equator is the Tropic of Cancer, and that to the south of the equator is the Tropic of Capricorn. The Arctic Circle is located 66½° north, and the Antarctic circle is located in the south.

These latitudinal lines use a site’s proximity to the equator to identify which climate zone that area belongs to and can tell you about its temperature. This is a way to give you a gist of the effects of latitude on climate. (See What is Imaginary Line?)

3. Why is Latitude important to Climate?

The equator is the most significant latitude. With the equator and other latitudes, the creation of distinct climate zones across the globe occurs. The region that receives the most sunlight between the tropic lines is known as the tropical zone. The region between the tropics and the polar circles is known as the temperate zone, and it is the only location on earth where all four seasons occur. In comparison, the tropics are the hottest region on Earth. Globally, there are a total of 180 degrees of latitude.

The effects of latitude on climate are discussed considering the following scenarios:

  • The area between the two tropics is called the Torrid zone or the Tropic zone. During the solstice and equinox, the sun shines directly on this area. An equinox happens one of the two times a year when the sun crosses the equator and almost everywhere on Earth, day and night are about the same length. It usually happens on the 21st of March and the 23rd of September.
  • The summer solstice is the time of year when the sun is highest in the sky and farthest north. This usually happens on June 22.
  • And the winter solstice happens when the sun is farthest south of the equator, which is usually on December 22.
  • Between the tropics and the subtropics are the temperate zones, where temperatures are usually mild and all four seasons (summer, spring, fall, and winter) happen every year. This is because the sun never shines directly on Great Britain, Europe, Northern Asia, North America, or Mexico. Southern Australia, New Zealand, southern South America, and South Africa, are all in the south temperate zone.
  • Then there are the frigid zones, which are the coldest places on Earth. They are outside of the Arctic and Antarctic circles and are very cold.

This is how all these effects of latitude on climate factors are dependent on the position of a place with respect to the Sun. Must see What is the Difference between Tropical and Polar Regions?

5. How does Latitude affect Climate Control?

The effects of latitude on climate and temperature are all about the range of solar intensity in a particular region that changes from season to season.

  • The area between the tropic lines, which receives the greatest sunlight, is referred to as the tropical zone, and the climate in this region is typically warm and humid, with significant amounts of precipitation. 
  • On the other hand, the area between the tropics and the polar circles is known as the temperate zone, and it is the only region of the world that experiences all four seasons.
  • And finally, the area beyond the polar circles is known as the polar zones, and the climate there is marked by long winters and abundant snowfall because there is not enough sunshine to warm the region. 

6. How does Latitude affect Temperature and Precipitation?

There are many effects of latitude on climate. The amount of precipitation becomes less frequent as one travels further away from the equator. The Earth’s topography, which includes mountains, has a big impact on how much rain falls. When humid air comes in from the ocean and moves up the slopes of a mountain, the air cools and the moisture from the sea starts to form a cloud. As the tiny water droplets in the cloud gather together, they get heavier and fall to the ground. When the air skims down the other side of the mountain, it heats up and the cloud disappears.

Most of the time, the side of a mountain that faces inland and away from the coast is dry. Also, a mountain range’s so-called rain shadow can sometimes reach more than a hundred miles downwind. The rain shadow regions have a lot of dry-arid lands. (See How Elevation affects climate?)

7. Why does Latitude cause Differences in Temperature?

There are five significant lines of latitude that are utilized in the process of climate analysis. The equator is the point on the planet that is the hottest part as the sun’s rays are at their strongest just over it. The proximity of a location to the equator helps these latitudinal lines (Tropic of Cancer, Tropic of Capricorn, The Arctic Circle, and The Antarctic Circle) determine what climate zone that location falls into.

The torrid zone, also known as the tropic zone, is the area that is between the two tropics and is the part of the earth where the sun shines directly on it at the solstices and equinoxes. This is how latitude causes differences in temperature. (See What is North Pole Temperature today?

8. How does Latitude High Mid Low impact Climate?

The region that receives the most sunlight between the tropic lines is known as the tropical zone. This zone’s climate is often warm and humid, and the majority of its places experience abundant precipitation. The temperate zones are between the two tropics and the circle separating the Arctic and Antarctic. This is the region that normally sees pleasant temperatures and all four seasons, including summer, spring, fall, and winter. This is because the sun never rises exactly over the territories.

9. How does Latitude affect the Climate in the USA?

The spring and autumnal equinoxes occur annually around the same time, coinciding with the sun’s equatorial crossing. At this time, day and night are roughly equivalent in length almost everywhere on Earth. The 21st of March and the 23rd of September are the typical dates for it to occur. North, Central, and South America’s Northern Tiers of temperate zones are located between the two tropics, and the circle that divides them are the Arctic and the Antarctic. This region typically has four distinct seasons each year: summer, spring, fall, and winter. (See Where is it Summer Right Now?)

10. How Latitude affect the Climate of India?

The latitude and longitude positions of any location in the world are referred to as their coordinates. The latitude at 20° and the longitude at 78 °, point to the location, which is India. The northern portion of India has a subtropical climate, whereas the southern portion has a tropical climate. India is located north of the equator, and the tropic of cancer traverses its area.

11. How does Longitude affects the Climate?

Longitude has a minimal effect on climate change, its most essential application is timekeeping. Longitudinal lines contribute to the development of the global time zone and the fact that while it is night in one hemisphere, it is day in the other. All other time zones are derived from the 0° longitude line that goes through Greenwich, England, close to London. Simply count the number of degrees of longitude between the two locations to calculate the time difference.

For example, if it is noon in Greenwich, which is located at 0° longitude, it will be 12:04 p.m. on a meridian that is located at 1°, etc. So, there is not much to discuss as to how longitude affects the climate as it is mostly related to the time zones.
