What are the doldrums and why are they nicknamed the horse latitudes?
Doldrums originated as a description of sea life in the area, while the term “horse latitudes” was coined due to the practice of throwing live horses or horse effigies overboard by early sailors to promote ship movement and speed.
What are horse latitudes also known as?
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies.
Which latitude is called doldrums?
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator.
Are the doldrums and horse latitudes?
The doldrums and the horse latitudes are two interesting terms used by meteorologists and sailors to describe two distinct areas over the ocean. Although they share the calm wind characteristic, they are located on two different degrees of latitude and display different characteristics of climate and weather.
How many horse latitudes are there?
Is this page helpful? Any of the two subtropical atmospheric high-pressure belts that are present around the Earth, around the latitudes 30° N – 35° N and 30° S – 35° S that can generate light winds and clear skies are known as Horse Latitudes.
Which latitudes are called doldrums?
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator.
Why do sailors avoid doldrums?
For centuries sailors dreaded the aptly named Doldrums. This band of windless, hot, and humid weather near the equator could stall sailing ships for weeks, driving the crew to distraction with the monotony and sometimes even leading to the onset of scurvy as fresh supplies ran out.
Why is there no wind at the equator?
The effects of the Doldrums are caused by solar radiation from the sun, as sunlight beams down directly on area around the equator. This heating causes the air to warm and rise straight up rather than blow horizontally. The result is little or no wind, sometimes for weeks on end.
Why is it called doldrums?
Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that's why they call it the doldrums.
Why do horse latitudes have high pressure?
Formation and Weather Conditions of Horse Latitudes When the air starts moving towards the mid-latitudes present on both sides of the Equator it cools and sinks. Because of this, a high-pressure ridge is created around the 30th degree parallel in both hemispheres.
What is it called when there is no wind at sea?
The "doldrums" is a popular nautical term that refers to the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters.
Has a hurricane ever crossed the equator?
However, the Coriolis force is zero at the equator. As a result, tropical cyclones are virtually nonexistent between latitudes 5(degrees) N and 5(degrees) S. National Weather Service records indicate that only one hurricane has ever crossed the equator.
Why is there no wind at doldrums?
The effects of the Doldrums are caused by solar radiation from the sun, as sunlight beams down directly on area around the equator. This heating causes the air to warm and rise straight up rather than blow horizontally. The result is little or no wind, sometimes for weeks on end.
Is doldrums same as ITCZ?
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator.
Why equatorial region is called doldrums?
Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that's why they call it the doldrums.
Why do the horse latitudes have such calm air?
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 do sailors say 2 6?
"Two, six, heave" is a phrase used to coordinate seamen's pulling. As used by sailors, the person at the front of the team will typically call out the "two, six" part of the chant. During this phase all members move their hands up the line ready to pull.

Why do hurricanes not happen off the coast of California?
"Essentially, the very cold water that upwells off the California coast and gives coastal California such a cool, benign climate also protects it from hurricanes. Real-time maps showing the distribution of the potential intensity of hurricanes clearly show the various regions worldwide that can sustain hurricanes.
Why don t hurricanes form in the Pacific?
Two factors explain why hurricanes very rarely form and come close to land on the west coast. First, hurricanes in the northern hemisphere move east to west, meaning storms that form in the Atlantic head straight for the American mainland, whereas in Pacific typically move away from land and out to sea.
Which belt is known as the Belt of doldrums and why?
Equatorial trough of low pressure is the zone of convergence of trade winds blowing equatorward from the sub-tropical belts of high pressure in the northern and southern hemisphere. Within this belt the winds are light and variable with frequent calms. That is why this belt is also known as doldrums.
What is the belt of doldrums?
doldrums, also called equatorial calms, equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator.
Why are they called doldrums?
Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that's why they call it the doldrums.
Why do horse latitudes have high-pressure?
Formation and Weather Conditions of Horse Latitudes When the air starts moving towards the mid-latitudes present on both sides of the Equator it cools and sinks. Because of this, a high-pressure ridge is created around the 30th degree parallel in both hemispheres.
