Chinook is a _______________ wind.
Hot, dry
Warm, dry
Cold, dry
none of the above
Identify the correct statement:-
Loo is a hot, dry wind which blows in the Southern Alps.
Monsoon winds change directions due to Coriolis effect.
Cyclones have high pressure area in the centre surrounded by areas of low pressure.
Anticyclones are associated with fine weather.
Identify the correct statment:-
The eye of a tropical cyclone is an area of calm with light winds, no rain and clear sky.
An anticyclone has an area of low pressure, surrounded by high pressure areas.
Tropical cyclones are more frequent in winters than in summers.
Rainfall in temperate cyclones is torrential.
Temperate cyclones are characterized by ____________.
heavy rainfall with thunderstorms
winds and rain active in every part of the cyclone
strong winds at all times of the cyclone
lot of destruction
Given below are names of four local winds. Identify the odd one out with the correct reason:-
Chinook, Mistral, Loo, Foehn.
Chinook, because it melts the snow on the Rockies, while the others are names of cold local winds.
Loo, because it blows from a desert, while the others are winds that blow in mountain or coastal regions.
Mistral, because it is the only cold local wind, while the others are warm local winds.
Foehn, because it actually blows on the windward side of the Alps, while the others blow on the leeward side of mountain ranges.
_________________________ results into land and sea breezes.
unequal pressure gradients
unequal heating of land and water
unequal distribution of insolation
none of the above
One of the following is a factor affecting atmospheric pressure. Identify the right one:-
Change of direction in winds due to shifting of pressure belts.
Influence of the Moon and Sun on the Earth.
Influence of Altitude on pressure.
Weather maps show isobars.
One of the following statements is true for Weather maps. Identify the correct statement:-
When the isobars are far apart, the pressure gradient is gentle and this indicates stormy weather.
When the isobars are closer, the pressure gradient is steep and this indicates calm weather.
When the isobars are closer, the pressure gradient is steep and this indicates stormy weather.
When the isobars are far apart, the pressure gradient is steep and this indicates pleasant weather.
Tropical cyclones are more frequent in summer because -
they require a sea-surface temperature of 26⁰ C and a high relative humidity.
they are frontal in origin.
the weather systems produce steep pressure gradients in the tropical regions.
they are often accompanied with anticyclones.
