Unable to sail and resupply due to lack of wind, crews often ran out of drinking water. To conserve scarce water, sailors on these ships would sometimes throw the horses they were transporting overboard. Thus, the phrase ‘horse latitudes’ was born.
What are the horse latitudes called by that name?
Horse latitudes, subtropical ridges or subtropical highs are the subtropical latitudes between 30 and 35 degrees both north and south where Earth’s atmosphere is dominated by the subtropical high, an area of high pressure, which suppresses precipitation and cloud formation, and has variable winds mixed with calm winds.
What are the horse latitudes and the doldrums?
Doldrums and horse latitudes are situated in different locations near the equator. Doldrums are placed at five degrees north and south of the equator. Meanwhile, horse latitudes are located at 30 degrees north and south latitude.
Which pressure belt is known as Horse Latitudes Why?
The subtropical high pressure belts are known region for spiritual peace and eternal calmness. It is much popular theory of the earlier times, the Spanish transported horses by ship to their colonies in the West Indies and to the Americas. This is how this pressure belt is known as ‘horse latitude’.
Which latitude is known as calms of Cancer?
One of the two light, variable winds and calms which occur in the centers of the subtropical high-pressure belts over the oceans; their usual position is about latitude 30°N, the horse latitudes.
Why are horse latitudes dry?
Horse latitude, either of two subtropical atmospheric high-pressure belts that encircle Earth around latitudes 30°–35° N and 30°–35° S and that generate light winds and clear skies. … Because they contain dry subsiding air, they produce arid climates in the areas below them.
Why is there high-pressure at 30 degrees from the equator?
The air that rises at the equator does not flow directly to the poles. Due to the rotation of the earth, there is a build up of air at about 30° north latitude. (The same phenomenon occurs in the Southern Hemisphere). Some of the air sinks, causing a belt of high-pressure at this latitude.
Why do sailors avoid the doldrums?
The crews of sailing ships dreaded the doldrums because their ships were often becalmed there; the designation for the resultant state of depression was apparently thus extended to these geographic regions themselves.
What are the 4 types of wind?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
What does the word doldrums mean?
1 : a spell of listlessness or despondency fighting off the winter doldrums. 2 often capitalized, oceanography : a part of the ocean near the equator abounding in calms (see calm entry 1 sense 1b), squalls, and light shifting winds.
Which belt is known as horse latitude?
Sub-Tropical high pressure belt, The horse latitudes are located at about 30 degrees north and south of the equator. It is common in this region of the subtropics for winds to diverge and either flow toward the poles (known as the prevailing westerlies) or toward the equator (known as the trade winds).
What is 30 degrees north of the equator?
Download coordinates as: KML
The 30th parallel north is a circle of latitude that is 30 degrees north of the Earth’s equatorial plane. It stands one-third of the way between the equator and the North Pole and crosses Africa, Asia, the Pacific Ocean, North America and the Atlantic Ocean.
Is it high or low pressure at the equator?
The high-pressure band is located about 30° N/S latitude and at each pole. Low pressure bands are found at the equator and 50°-60° N/S. Usually, fair and dry/hot weather is associated with high pressure, with rainy and stormy weather associated with low pressure.
How many latitudes are there in total?
Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers).
What are the 3 wind belts?
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10).
What are the 7 pressure belts?
On the earth’s surface, there are seven pressure belts. They are the Equatorial Low, the two Subtropical highs, the two Subpolar lows, and the two Polar highs. Except for the Equatorial low, the others form matching pairs in the Northern and Southern Hemispheres.
