The winds which blow between 30° N and 60° S latitudes through-out the year are known as westerlies.
The moist air masses that cause winter rains in North-Western region of India are part of westerlies. Which of the statements given above is/are correct? a) 1 only b) 2 only c) Both 1 and 2 d) Neither 1 nor 2
The correct answer is 2 only.
Westerlies
These are permanent winds.
These are prevailing winds that flow from the west towards the East.
Westerlies flow between 30°N-60°N and 30°S-60°S degrees latitude. Hence statement 1 is NOT correct.
This is also known as anti trades winds as it originates from the high-pressure area of Horse latitude and flows towards the subpolar low-pressure area.
It blows from South West to North East in the Northern hemisphere and from Northwest to southeast in the southern hemisphere.
These are stronger in the Southern hemisphere due to the vast ocean and comparatively less land.
It is best observed between 40 to 60-degree latitude and these latitudes are also known as the Roaring forties, Furious fifties, and shrieking sixties.
There are fluctuations in the subpolar region. Thus, they produce wet spells due to variations in weather.
The moist air masses that cause winter rains in the North-Western region of India are part of Western disturbances that originate from the Mediterranean Sea. Hence statement 2 is correct.
