TEST SERIES- 1O (II)

In the Northern Hemisphere, tropical cyclones and middle latitude cyclones are similar in that both

• Originate over warm ocean

• Intensify with increasing height above the ground

• Generally move from East to West

• Have winds that blow counter clockwise around their centres

Fohn and Chinook winds are experienced in

• The valleys of the Northern Alps is Switzerland and on the Eastern slopes on Rockies in North America

• The Eastern slopes of Southern Alps in Switzerland and on the western slopes on Andes in South America

• Po valley of France and in Newfoundland

• Netherlands and New Zealand

Willy-willy is

• A type of free grow in temperate region

• A wind that blow in a desert region

• A tropical cyclone of the NorthWest Australia

• A kind of common fish found near Lakshadweep

Winds and air currents differ in the aspect that

• Air currents blow much faster than winds

• Air currents are always moisture laden while the winds are usually dry

• The winds blow on lands while air currents blow over seas and oceans

• Winds are horizontal movements of air while air current are the vertical movements of air

Which of the following statement is correct?

• Roaring forties are the Southern latitudes where Westerlies are prevalent

• Monsoons are local seasonal winds

• Doldrum belt lies between 10°N and 10° South latitudes

• Horse latitudes are found between trade winds and Westerlies

An observer in the Northern Hemisphere who stands with his back to the wind will have lower pressure to his left and higher pressure to his right. This is known by which one of the following?

• Bergeron-Findeisen theory

• Buys Ballot’s law

• Walker circulation

• Stoke’s law

Fohn and Chinook winds are

• Caused by strong regional winds while passing over a mountain range

• Caused by strong local wind

• Caused by Westerlies

• Caused by humid Westerlies

Which of the following statements about Westerlies is not correct?

• They blow from subtropical high to equatorial low

• Westerlies of Southern Hemisphere are stronger

• In Northern Hemisphere they blow from South-West to NorthEast

• In Northern Hemisphere they blow from South-West to NorthEast

What are Chinooks?

• Cold local winds which blow from North-West to South-East direction in Spain

• Extremely dry winds blowing from North-East and East to West in Eastern parts of Sahara desert

• Warm and dry winds which blow down the Eastern slopes of Rocky Mountains of North America

• Warm and dry winds along the northern slopes of Alps Mountains

What is the characteristic of planetary winds?

• These flow from the belts of high pressure to the belts of low pressure

• These flow from the belts of low pressure to the belt of high pressure

• These do not flow to any centre of pressure

• None of the above
