A region’s prevailing and dominant winds are the result of global patterns of movement in the Earth’s atmosphere. In general, winds are predominantly easterly at low latitudes globally. … Prevailing winds can vary due to the uneven heating of the Earth.
What are global winds?
Global Winds. Global winds are winds that occur in belts that go all around the planet (Figure below). Like local winds, global winds are caused by unequal heating of the atmosphere. [Figure 2] Global winds occur in belts around the globe.
Local winds blow from the poles to the equator, whereas global winds blow west to east. Local winds curve due to the Coriolis effect, whereas global winds blow in a straight path. Local winds blow over long distances, whereas global winds blow over short distances.
Are prevailing winds global or local?
Local winds are winds that blow over a limited area. They are influenced by local geography, such as nearness to an ocean. They include land and sea breezes as well as monsoons. Global winds occur in belts around the globe.
The westerlies or the prevailing westerlies are the prevailing winds in the middle latitudes (i.e. between 35 and 65 degrees latitude), which blow in areas poleward of the high pressure area known as the subtropical ridge in the horse latitudes.
What are the three types of prevailing winds?
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 4 global winds?
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 are the 5 types of winds?
The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles.
What are the prevailing winds in the Philippines?
What are global wind patterns called?
Explanation: Global Wind Patterns wind belts of the general circulation. The global wind pattern is also known as the “general circulation” and the surface winds of each hemisphere are divided into three wind belts: Polar Easterlies: From 60-90 degrees latitude.
What are planetary or prevailing winds?
Planetary winds are those winds which blow regularly corresponding to the major pressure belts of the world. These winds blow in certain latitudes. Since they blow regularly, they are also known as the Prevailing winds.

Answer. The global wind pattern is also known as the “general circulation” and the surface winds of each hemisphere are divided into three wind belts: Polar Easterlies: From 60-90 degrees latitude.
How do prevailing winds work?
Winds occur where high-pressure air masses seek low-pressure areas. Prevailing winds are largely predictable and named for broad areas of the Earth over which they form. Convection cells circulate air flow and help regulate temperature around the globe.
What are planetary winds 6?
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.
What are variable winds?
Variable Wind Same as Variable Wind Direction; a condition when. (1) the wind direction fluctuates by 60° or more during the 2-minute evaluation period and the wind speed is greater than 6 knots; or. (2) the direction is variable and the wind speed is less than 6 knots.
What two factors determine the direction of the global winds?
4. What two factors determine the directions of the global winds? These are caused by the rotation of the Earth, and unequal heating of Earth’s surface 5.
What prevailing winds influenced dry season in the Philippines?
The Philippines weather patterns are created by the prevailing winds of the southwest monsoon (known as the habagat) from May to October and the northeast monsoon (known as the amihan) from November to early May.

Has the Philippines ever snowed?
Has the Philippines ever snowed? According to meteorologists, there has never been snowfall recorded in the Philippines. Even during the coldest months of the year, the average temperature hovers around 20 degrees Celsius or 68 Fahrenheit.
What is the difference between the jet stream and the prevailing winds?
What do you understand by global wind and pressure patterns also explain wind and pressure features at higher altitude?
Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earth’s surface also forms large global wind patterns. In area near the equator, the sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles.
In which direction do prevailing westerlies flow?
Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. They tend to blow from the high pressure area in the horse latitudes towards the poles. These prevailing winds blow from the west to the east steering extratropical cyclones in this general manner.
What are prevailing winds Class 9?
The Planetary winds are also known as permanent winds or prevailing winds as they continuously blow in a particular direction throughout the year. Pressure belts control them. The planetary wind is of three types: the trade wind, the Westerlies and the Polar Easterlies.
Which of the following global winds form near the equator?
The global wind belts are the three wind belts or wind patterns that cover the planet: the tropical easterlies (or the trade winds) are found near the equator, the polar easterlies are found at the north and south poles, and the prevailing westerlies are found between the two.
