What are the examples of westerlies?
An example of the impact of the westerlies is when dust plumes, originating in the Gobi desert combine with pollutants and spread large distances downwind, or eastward, into North America.
Where are westerlies located?
The westerlies occur in the mid-latitudes. The mid-latitudes are the areas between 30 and 60 degrees north and south of the equator. Places within these regions include the US, Canada, Europe, Southern Australia, and Chile. Most countries that experience westerly winds are located within the Northern Hemisphere.
Is Australia in the westerlies?
The midlatitude westerlies, located between Australia and Antarctica (Fig. 1), are part of the Southern Annular Mode (SAM). The seasonal movement of the ITCZ controls the summer and winter monsoons over Southeast Asia and Australia.
Is North America in the westerlies?
How do prevailing westerlies affect North America? These prevailing winds blow from the west to the east, and steer extra-tropical cyclones in this general direction. … The westerlies explain why coastal North America tends to be wet, especially from Northern Washington to Alaska, during the winter.
What are westerlies Class 7?
Westerlies are also known as Shrieking Sixties, Furious Fifties and Roaring Forties. These winds blow from the subtropical high-pressure belts towards sub-polar low-pressure belts. The westerlies of the Southern hemisphere are stronger and constant as compared to that of the Northern hemisphere.
Are westerlies cold or warm?
The winter westerlies, often from the southwest, bring in warm tropical air; in summer, by contrast, they veer to the northwest and bring in cooler Arctic or subarctic air. In Mediterranean Europe the rain-bearing westerlies chiefly affect the western areas, but only in winter.
Is Sydney subtropical?
The climate of Sydney is humid subtropical (Köppen Cfa), shifting from mild and cool in winter to warm and hot in the summer, with no extreme seasonal differences as the weather is moderated by proximity to the ocean, although more contrasting temperatures are recorded in the inland western suburbs.
What is moisture Class 7?
Q15: What is moisture? Ans: This term refers to degree of moisture present in the air . There is a definite limit to the quantity of moisture that can be held by the air at a specific temperature.
What are variable westerlies?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
Is Melbourne subtropical?
In Melbourne, a city of southern Australia and the capital of the state of Victoria, the climate is subtropical oceanic, with mild winters and pleasantly warm summers.
What are the westerlies?
The Westerlies are winds that blow in the middle latitudes between 30 and 60 degrees latitude.
Why do the westerlies run west to East?
The name of these unique winds comes from the direction of their origin; the westerlies run west to east while other winds run east to west. Essentially, the air around the equator rises as it heats up. This upward motion causes the cooler air at higher altitudes to be moved to the previously mentioned latitudes.
What is an example of the impact of the westerlies?
An example of the impact of the westerlies is when dust plumes, originating in the Gobi desert combine with pollutants and spread large distances downwind, or eastward, into North America.
What are the westerlies and trade winds?
The Westerlies and Trade Winds. As the dominant winds in the middle latitude regions, the westerly winds have had a significant impact on trade routes throughout history. This importance to trade is particularly true of the “Roaring Forties”, some of the strongest westerly winds in the southern hemisphere between 40 and 50 degrees latitude.
