Which winds are called easterlies?
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region.
Where are the easterlies?
They are dry and cold prevailing winds that blow specifically from the east, hence the term easterlies. They occur around high-pressure zones within the North and South Poles.
What are easterlies quizlet?
the polar easterlies are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards low-pressure areas within the Westerlies at high latitudes.
Where does an easterlies wind come from?
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. Polar easterlies flow to low-pressure areas in sub-polar regions. Westerlies are prevailing winds that blow from the west at midlatitudes.
What does the word easterlies mean?
1 : situated toward or belonging to the east the easterly shore of the lake. 2 : coming from the east an easterly storm. easterly. noun. plural easterlies.
How do easterlies form?
Polar easterlies blow from the polar high pressure belts towards the temperate low pressure belts. These are extremely cold winds that come from the Tundra and Icecap regions of the poles. The Polar Easterlies are more regular in the southern hemisphere in comparison to the northern hemisphere.
Why are they called easterlies?
Polar easterlies are dry and cold prevailing winds that blow from the east. Trade winds are the powerful prevailing winds that blow from the east across the tropics. As these winds blow from east towards west. Hence they are called easterlies.
Where do the winds known as easterlies occur quizlet?
The polar easterlies form when the atmosphere over the poles cools. This cool air then sinks and spreads over the surface. As the air flows away from the poles, it is turned to the west by the Coriolis effect. Again, because these winds begin in the east, they are called easterlies.
What is a characteristic of polar easterlies quizlet?
What is a characteristic of polar easterlies? Winds flow from the east (northeast in the Arctic and southeast in the Antarctic). What general part of the general circulation would you find the “doldrums”? Belt of the intertropical convergence zone.
Why are easterlies called trade winds?
The trade winds were named by the crews of sailing ships that depended on the winds during westward ocean crossings.
How do you spell easterlies?
noun, plural east·er·lies. a wind that blows from the east.
Are easterlies and trade winds the same?
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.
How do winds form?
During the day, air above the land heats up faster than air over water. Warm air over land expands and rises, and heavier, cooler air rushes in to take its place, creating wind.
What do easterlies do?
Easterlies mean winds blowing from the east. The name of the permanent winds comes from the direction of their origin. Polar easterlies are dry and cold prevailing winds that blow from the east. Trade winds are the powerful prevailing winds that blow from the east across the tropics.
What is the easterly wind in the equatorial region due to the global air circulation called quizlet?
These steady easterly winds are called the trade winds. In the mid latitudes between 30 and 60 degrees north and south, winds that blow toward the poles are turned toward the east by the Coriolis effect.
What is a characteristic of westerly winds?
They blow in the middle latitudes between 35 and 65 degrees latitude. They blow from the subtropical high-pressure belts towards sub-polar low-pressure belts. The winds blow from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.
What is a characteristic of trade winds?
The main characteristics of the Trade winds are: The Trade winds blow in the tropics between the sub tropical high pressure belt to the equatorial low pressure belt between 30°N and 30°S. Trade winds are warm winds and hence they pick up moisture and bring heavy rainfall on the eastern sides of the tropical islands.
Why are easterly winds called easterlies?
As wind blows from high pressure to low pressure it will be deflected to the right, or west, in the Northern Hemisphere, so as the air heads back to the equator, it is going to be deflected westward. So, like the polar easterlies, this wind originated from the east so it’s called an easterly. And here it comes! Look out, piggy number two!
What are trade winds and easterlies winds?
Those are trade winds, westerlies, and easterlies. Westerlies winds blow between 35º to 65º latitude of both hemispheres, predominantly over the ocean, from west to east. Polar Easterlies occur because of airflow from the polar regions of high air pressure towards depressions and turn west.
What are polar easterlies and westerlies?
Polar Easterlies – In both hemispheres, the westerlies start rising and cooling between 50° and 60° latitude as they approach the poles. They meet extremely cold air flowing toward the equator from the poles and form the polar easterlies.
What are the westerly winds called?
The westerly winds, like a current, exist only in the western parts of the continent, and they are permanent. They stretch between 40-65, and their strength increases with increasing latitude, so they are also known as noisy forties, with even stronger winds at 50 – angry fifties, and at 60 – terrible sixties.
