GENERAL KNOWLEDGE

Detailed explanation-1: -The easterlies or polar easterlies are located between 60° and 90° latitude in both northern and southern hemispheres and are named after the direction they originate from. These are formed when the cool air from the poles sinks and moves towards the equator.

Detailed explanation-2: -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.

Detailed explanation-3: -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.

Detailed explanation-4: -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.
