What do you mean by westerlies?
/ (ˈwɛstəlɪz) / pl n. meteorol the prevailing winds blowing from the west on the poleward sides of the horse latitudes, often bringing depressions and anticyclones.
How are westerlies formed?
They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner. Tropical cyclones which cross the subtropical ridge axis into the westerlies recurve due to the increased westerly flow.
What are the characteristics of westerlies?
The main characteristics of the Westerlies are: They blow from sub-tropical high pressure belts to the sub-polar low pressure belts between 30° to 60°N of the Equator in the temperate latitudes.
How does coriolis force affect climate?
Under the effect of coriolis force, the trade winds moving from sub-tropical high pressure belts to equational low pressure belts become north-east trade winds in the northern hemisphere and south-east trade winds in the southern hemisphere.
Where do the trade winds and the westerlies come from?
Westerlies. The general atmospheric circulation. Trade winds (red), westerlies (white) and the South Pacific anticyclone (blue). 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 …
When do the westerlies occur in the northern hemisphere?
The Westerlies are winds that blow in the middle latitudes between 30 and 60 degrees latitude. The westerly winds occur from December to February in the northern hemisphere.
What’s the difference between westerlies and easterlies in winter?
The difference in speed between these two types of air is what is felt on the surface of the earth. Meteorologists report that the westerlies have higher speeds and more force during the winter season, which in the northern hemisphere is from December to February and in the southern hemisphere is from June to August.
How are the westerlies related to the South Pole?
In turn, this warmer temperature causes the westerly winds to grow in strength and speed. As these winds become stronger, they prevent the warm air from making its way to the south pole. Therefore, the Antarctic coastal zones are more affected by the increased temperatures.
