Why is the air pressure at the equator lower than the pressure at 30 N and 30 S?
Equatorial regions is hotter and the air above expands, becomes less dense and rises. This produces a low pressure belt at this latitude. 1. 30o N & S latitudes are high pressure belts.
Which direction do the winds travel between the equator and 30 degrees?
Between about 30 degrees north and 30 degrees south of the equator, in a region called the horse latitudes, the Earth’s rotation causes air to slant toward the equator in a southwesterly direction in the northern hemisphere and in a northwesterly direction in the southern hemisphere. This is called the Coriolis Effect.
Why does air sink at 30 degrees latitude?
The region in which the air rises and then diverges aloft develops a belt of low pressure (the ITCZ) which is labeled as the equatorial low in Figure 1. At around 30 degrees latitude convergence of air aloft leads to sinking air and to the development of subtropical high pressure systems.
What is the name for the winds blowing with a very high speed at a height of 3 km from the surface in the upper?
The name for wind blowing with very high speed at height of 3 kilometre from the upper atmosphere is called jet stream. The upper atmosphere is called Exosphere. Its range lie from sea level is 700 km to 10,000 km above the earth surface.
What is the name for the wind blowing with a very high speed?
In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. Short bursts of high speed wind are termed gusts.
Why does wind change direction?
Wind carries moisture into an atmosphere, as well as hot or cold air into a climate which affects weather patterns. Therefore, a change in wind results in a change of weather. Wind travels from areas of high pressure to areas of low pressure. Additionally, heat and pressure cause the wind to shift direction.
Why do the winds curve to the east between 30 60 degrees?
The Coriolis effect is the apparent curvature of global winds, ocean currents, and everything else that moves freely across the Earth’s surface. The curvature is due to the rotation of the Earth on its axis. Between thirty and sixty degrees latitude, the winds that move toward the poles appear to curve to the east.
What type of wind is found between the latitudes of 0 degrees and 30 degrees?
Tropical Easterlies
What causes winds to curve?
Warm air rises at the equator and moves toward the poles. In the southern hemisphere, winds appear to curve to the left. This is known as the Coriolis effect, which is the apparent shift in the path of any fluid or object moving about the surface of the Earth due to the rotation of the Earth.
Where does air rise the strongest on earth?
As the difference in temperature increases between the two locations the strength of the wind increases. Therefore, the regions around 30° N/S and 50°-60° N/S are also regions where the wind, in the upper atmosphere, is the strongest.
