What Wind Systems Move Air From About 30° To 60° North Or South Latitude?


What Wind Systems Move Air From About 30â° To 60â° North Or South Latitude??

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. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies).

What wind systems move air from about 60 north or south latitude?

The polar easterlies are one of the five primary wind zones known as wind belts that make up our atmosphere’s circulatory system. This particular belt of wind begins at approximately 60 degrees north and south latitude and reaches to the poles.

What wind systems move air from about 30 north or south latitude?

What wind systems move air from about 30° north or south latitude toward the equator? The northeast trade winds in the northern hemisphere and the southeast trade winds in the southern hemisphere. 2. Describe the movement of air in the huge convection current between 30° north latitude and the equator.

What is responsible for causing wind from north south or south north?

Prevailing winds are winds that blow from a single direction over a specific area of the Earth. Areas where prevailing winds meet are called convergence zones. Generally prevailing winds blow east-west rather than north-south. This happens because Earth’s rotation generates what is known as the Coriolis effect.

What wind systems move air from about 30 to 60?

In the circulation cell that exists between 60° and 30° north the movement of air produces the prevailing westerlies. In the tropic circulation cell the northeast trade winds are produced. These are the so-called permanent wind systems of the each.

Which prevailing winds can be found between 60 and 90 degrees latitude?

Polar Easterlies: From 60-90 degrees latitude. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies). Tropical Easterlies: From 0-30 degrees latitude (aka Trade Winds).

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.

How does the movement of hot air at the equator and cold air at the poles produce global wind patterns?

Warm air rises at the equator and moves toward the poles. At the poles the cooler air sinks and moves back toward the equator. … Global winds do not move directly from north to south or south to north because the Earth rotates. All winds in the Northern Hemisphere appear to curve to right as they move.

Where are the trade winds?

The trade winds can be found about 30 degrees north and south of the equator. Right at the equator there is almost no wind at all—an area sometimes called the doldrums.

Why is the wind on Earth not blowing straight?

Hot air rises from the equator moves to the both poles where it cools down and sinks back to the surface. … Also air with higher pressure will move towards the ones with lower pressure. Although this is true wind doesn’t blow in a straight line. Again that is because of the rotation of the Earth.

Why wind blows from west to east?

Why the wind moves from west to east.

However air moving toward the poles retains its eastward momentum while the earth’s rotational velocity decreases beneath it. The result is the wind moves faster than the earth rotates so it moves from west to east (relative to us at the surface). The Coriolis effect.

Which factor is responsible for blowing of wind?

The Short Answer: Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.

What direction do the winds of a high pressure system move in the Southern Hemisphere?

In the Southern Hemisphere winds blow around a high pressure in an anticlockwise direction and around a low pressure in a clockwise direction.

How are the polar easterlies affected by the Coriolis effect?

Cold air subsides at the pole creating the high pressure forcing a southerly (northward in the southern hemisphere) outflow of air towards the equator. This outflow is then deflected westward by the Coriolis effect therefore these prevailing winds blow from the east to the west.

What type of global wind is mainly responsible for the weather in the United States and Canada?

Prevailing westerlies

Prevailing westerlies in the Northern Hemisphere are responsible for many of the weather movements across the United States and Canada. At about sixty degrees latitude in both hemispheres the prevailing westerlies join with polar easterlies to reduce upward motion.

Why are polar global winds called polar easterlies?

The air at the poles is cold and dense creating high pressure. … Well winds are named based on where they start so since they start in poles and due to the Coriolis effect blow from the east they are called polar easterlies.

What is the direction of prevailing winds between 90 degrees north and 60 degrees north latitude?

The polar easterlies are named as such because they are the type of prevailing winds closest to the North and South poles. The polar easterlies mainly blow from east to west between 60 and 90 degrees latitude.

What are the 3 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 prevailing winds converge in the mid latitude cyclone?

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.

Why are the winds different every 30 degrees in latitude across the globe?

Prevailing winds are winds that blow consistently in a given direction over a particular region on Earth. Due to factors such as uneven heating from the Sun and the Earth’s rotation these winds vary at different latitudes on Earth.

What is the direction of the planetary winds between the equator and 30 N?

east to west

Global Wind Patterns

Water in the surface currents is pushed in the direction of the major wind belts: trade winds: east to west between the equator and 30oN and 30oS. westerlies: west to east in the middle latitudes.

What direction do global winds move between 30 degrees N and 60 degrees N?

The Prevailing Westerlies are the dominant winds found between 30 degrees and 60 degrees of latitude and the Coriolis Effect moves them from west to east. Hint: Winds are always named from the direction that they start from.

How does the air move at the equator?

In the tropics near the equator warm air rises. … When the air cools it drops back to the ground flows back towards the Equator and warm again. The now warmed air rises again and the pattern repeats. This pattern known as convection happens on a global scale.

How does warm air and cold air move in the atmosphere?

Within the troposphere are convection cells (Figure below). Warm air rises creating a low pressure zone cool air sinks creating a high pressure zone. Air that moves horizontally between high and low pressure zones makes wind. … Convection in the atmosphere creates the planet’s weather.

What is moving air called Why does air move in the atmosphere?

Just like water currents in the ocean the atmosphere has air currents that flow from one place to another. Air is constantly moving around the earth. This moving air is called wind. Winds are created when there are differences in air pressure from one area to another. … This is what makes air move creating the wind.

What is north-east trade wind?

n. Often trade winds. any of the nearly constant easterly winds that dominate most of the world’s tropics and subtropics blowing mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere. [1625–35]

What are trade winds called in Northern Hemisphere?

tropical easterlies
What Are Trade Winds? Trade winds can be defined as the wind that flows towards the equator from the north-east in the Northern Hemisphere or from the south-east in the Southern Hemisphere. These are also known as tropical easterlies and are known for their consistency in force and direction.

What is the latitude for the trade winds quizlet?

The trade winds are located between 0 degrees and 30 degrees latitude in both the northern and southern hemisphere.

Which way does the air move from the North Pole?

We call this the Coriolis force. In the Northern Hemisphere it exerts a force to the right (and to the left in the Southern Hemisphere) so a parcel of air moving toward the North Pole will be deflected toward the right.

What direction do winds curve in each hemisphere?

Because the Earth rotates on its axis circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.

What prevents wind from blowing directly from the North Pole to the south Pole?

This is called the Coriolis effect or the Coriolis force (although it is not really a force).

What direction is a NW wind blowing?

Cardinal Point Abbreviation Azimuth Degrees
West by North WbN 281.25°
West-Northwest WNW 292.50°
Northwest by West NWbW 303.75°
Northwest NW 315.00°

What is the wind direction in the Northern Hemisphere quizlet?

Winds around a low pressure system (cyclonic winds) are clockwise in the Northern Hemisphere. Winds around a low pressure system (cyclonic winds) are counterclockwise in the Northern Hemisphere. Winds around a high pressure system (anticyclonic winds) are clockwise in the Northern Hemisphere.

What are the two factors on which the direction of wind depends?

Answer: Wind direction depends upon the Coriolis effect the and friction. *Remember the Earth is always spinning beneath us! As objects move in the atmosphere the Earth is turning under them!
