Climate, Weather, and Geography
2,194 Questions
Climate, weather, and geography examine temperature variations, wind patterns, atmospheric hazards, and global climate zones. This hub addresses climographs, thunderstorm triggers, and regional climate descriptors. These concepts are essential for UPSC, SSC, and RRB general studies and geography exams.

-
a and b
-
a, b and c
D
Correct answer
Explanation
This is the correct answer a s statements a and b are correct about isotherms.
-
Latitude
-
Distance of Sun from earth
-
Air mass circulation
-
Distance from the sea
-
Altitude
B
Correct answer
Explanation
This is the correct answer choice. The variation in the solar output does not have great effect on daily weather changes on the surface of the earth. Thus, the distance of earth from the sun has the least affect on the weather changes on the surface of the earth.

b and c
B
Correct answer
Explanation
This is the correct answer. Surface inversion causes fog during winter mornings. The heat of the day is radiated off during the night, and by early morning hours, the earth is cooler than the air above. Smoke and dust particles get collected beneath the inversion layer and spread horizontally to fill the lower strata of the atmosphere. Air drainage causes surface inversion, which causes fog.

The above climate data resembles that of which one of the following cities?
-
Buenos Aires
-
Tokyo
-
Melbourne
-
San Francisco
D
Correct answer
Explanation
The climate data shows mild, wet winters (9-10°C, 88-104mm rain) and dry, mild summers (17-18°C, 1-5mm rain). This is a classic Mediterranean climate pattern, which San Francisco exhibits. Tokyo has summer rainfall, Melbourne has winter rainfall peaks in different months, and Buenos Aires is in the Southern Hemisphere with reversed seasons.
A
Correct answer
Explanation
During winter mornings, the exposed surface cools by radiating its heat. Thus, water vapour present in the atmosphere condenses, resulting in the formation of water droplets on the exposed surfaces. These water droplets are known as dew. Dew is formed very easily on grasses and leaves of plants.
B
Correct answer
Explanation
Mist is the formation of water droplets in air from water vapours by the process of condensation, near or in contact with the earth’s surface during the winters. Mist is different from fog only by visibility. Mist does not reduce visibility as much as fog does.
-
the polar high
-
the equatorial low
-
the subtropical high
-
cyclonic circulation
-
the general circulation of the atmosphere
D
Correct answer
Explanation
The wind circulation around a low is called cyclonic circulation.
-
The latitudinal variation of atmospheric heating.
-
The emergence of pressure belts.
-
The migration of belts following apparent path of the sun.
-
The distribution of continents and oceans.
-
The gravitational pull.
E
Correct answer
Explanation
It depends upon the rotation of the earth. It does not depend upon the gravitational pull. Thus, this is the correct answer.
-
The cells from which westerlies arrive are called Ferrel cells.
-
Hadley cells are the source for westerlies.
-
Polar cells blowing towards the middle latitudes cause the westerlies.
-
The transfer of heat energy from lower latitudes to higher latitudes causes the westerlies.
-
None of the above
A
Correct answer
Explanation
This is the correct answer. Westerlies are caused by Ferrel cells. In the middle latitudes the circulation is that of sinking cold air that comes from the poles and the rising warm air that blows from the subtropical high. At the surface these winds are called westerlies and the cell is known as the Ferrel cell.
-
Maritime tropical (mT)
-
Continental tropical (cT)
-
Maritime polar (mP)
-
Continental polar (cP)
-
Maritime arctic (mA)
E
Correct answer
Explanation
This is incorrect. The recognszed air mass is continental arctic or cA along with the others mentioned above.
-
Only a
-
Only b
-
Only c
-
Only a and b
-
Only b and c
D
Correct answer
Explanation
This is the correct answer. Both these statements are correct about El Nino.
-
polar
-
warm
-
stationary
-
occluded
-
middle latitude
A
Correct answer
Explanation
This is correct. Extra tropical cyclones form along the polar front.
-
The cold front moves faster than the warm front ultimately overtaking the warm front, which is completely lifted up and the front is occluded and the cumulus clouds are formed.
-
If an air mass is fully lifted above the land surface, it causes cumulus clouds.
-
The cold front approaches the warm air from behind and pushes the warm air up resulting in the development of cumulus clouds along the cold front.
-
All of the above.
-
None of the above.
C
Correct answer
Explanation
This is correct about cumulus clouds.
-
Thunderstorms
-
Tornadoes
-
Water sprouts
-
Tropical cyclones
-
Frontogenesis
A
Correct answer
Explanation
Thunderstorms are caused by intense convection on moist hot days.
-
Large sea surface with temperature higher than 27° C.
-
Presence of the Frictional force.
-
Small variations in the vertical wind speed.
-
A pre-existing weak low pressure area.
-
Upper divergence above the sea level system.
B
Correct answer
Explanation
No, coriolis force should be present.
