The horse latitudes are subtropical regions known for calm winds and little precipitation. The horse latitudes are regions located at about 30 degrees north and south of the equator. These latitudes are characterized by calm winds and little precipitation.

What causes wind?

Wind is the movement of air caused by the uneven heating of the Earth by the sun. … Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time cooler denser air moves over Earth’s surface toward the Equator to replace the heated air.

What are types of wind?

This classification is based on the periodicity of occurrence and location of occurrence.
  • Primary Wind or Planetary Wind. …
  • Secondary Wind or Periodic Wind. …
  • Tertiary Wind or Local Wind. …
  • Trade Winds. …
  • The Westerlies. …
  • Polar Easterlies. …
  • Monsoon Winds. …
  • Land Breeze and Sea Breeze.

What are planetary winds name them?

In the planetary wind system there are three main types of planetary winds – The Trade Winds The Westerlies and The Easterlies.

Why is southern hemisphere warmer?

The southern hemisphere is warmer than the northern hemisphere because more of its surface area is water.

Why is there so little land in the southern hemisphere?

This is because the Southern Hemisphere has significantly more ocean and much less land water heats up and cools down more slowly than land. The differences are also attributed to oceanic heat transfer and differing extents of greenhouse trapping.

What is Southern Hemisphere and northern hemisphere?

What are the 3 types of winds?

The three chief types of winds are Trade winds Westerlies and polar winds.

What is the direction of deflection in the Southern Hemisphere?

In the Southern Hemisphere currents are deflected to the left. As a result storm systems seem to rotate clockwise. Outside storm systems the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator for instance it flows toward the poles.

Why does wind between the equator and 30 degrees south come out of the southeast?

Why does wind between the equator and 30 degrees south come out of the southeast? Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect. … Wind near the north pole would move to the northeast and the wind near the south pole would move to the southeast.

Why does the Coriolis effect reverse direction between the northern and southern hemispheres?

Why does the Coriolis Effect reverse direction between the Northern and Southern Hemisphere? The reversal is related to the difference in an observer’s sense of Earth’s rotation in the two hemispheres. … Friction slows horizontal winds blowing within about 1000 m of Earth’s surface.
