How are planetary winds related to pressure belts of the globe?
Planetary or permanent winds blow from high pressure belts to low pressure belts in the same direction throughout the year. They blow over vast area of continents and oceans. They are easterly and westerlies and polar easterlies.
What are the major planetary winds and pressure belts what are their main characteristics?
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. There is a pattern of alternate high and low-pressure belts over the earth.
How do planetary wind and pressure belts affect climate?
The tilt of the axis allows differential heating of the Earth’s surface, which causes seasonal changes in the global circulation. On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather.
What are planetary of prevailing winds?
What are Planetary Winds? The winds that flow throughout the year from one latitude to another latitude because of latitudinal differences in the air pressure are called planetary winds. They are also called prevailing winds. Planetary winds blow from a single direction over a specific area over the earth.
Which factor is responsible for planetary wind belts?
The tilt of Earth’s axis.
How does planetary winds affect climate?
The winds move air masses, which causes weather. The direction of prevailing winds determines which type of air mass usually moves over an area. For example, a west wind might bring warm moist air from over an ocean. An east wind might bring cold dry air from over a mountain range.
What are the effects of planetary winds?
1.) Planetary Winds affect climate because they cause the land to cool down. 2.) They also cause the moisture in the air to condense and then form clouds,which results in precipitation.
How can prevailing winds affect climate?
Although prevailing winds often originate from the ocean and bring moisture to the land, they can also do the opposite. When the wind blows from a land region, there is no moisture or water involved. This means that the winds bring more dry air to the climate and lessen the chance of rainfall.
How do wind belts affect climate?
What are pressure belts?
A region on the earth that is dominated by either high pressure cells or low pressure cells is called a pressure belt. The horizontal distribution of air pressure across the latitudes is characterised by high or low-pressure belts.
How pressure belts are formed?
Formation. The air from sub-polar low pressure belts after saturation becomes dry. This dry air becomes cold while moving towards poles through upper troposphere. The cold air (heavy) on reaching poles subsides creating a high pressure belt at the surface of earth.
How are planetary winds formed?
Planetary or permanent winds blow from high-pressure belts to low-pressure belts in the same direction throughout the year. They blow over a vast area of continents and oceans. They are easterly and westerlies and polar easterlies.
