Which of the following weather phenomena of the winter months in India is/are brought in by the westerly flow from the Mediterranean region?

  1. Pressure and surface winds

  2. North easterly winds

  3. Western cyclonic disturbances

  4. Sub-tropical easterly jet stream

  5. Southern oscillations


Correct Option: C
Explanation:

This is the correct answer as the western cyclonic disturbances are a weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region.

Which of the following is called the monsoon trough in the monsoon season?

  1. The differential heating and cooling of land and water creates low pressure on the landmass of India while the seas around experience comparatively high pressure.

  2. The shift of the position of Inter Tropical Convergence Zone (ITCZ) in summer, over the Ganga plain which is normally positioned about 5°N of the equator.

  3. The presence of the high-pressure area, east of Madagascar, approximately at 20°S over the Indian Ocean.

  4. The strong vertical air currents and the formation of low pressure over the Tibetian plateau at about 9 km above sea level.

  5. The presence of the tropical easterly jet stream over the Indian peninsula during summer.


Correct Option: B
Explanation:

This is the correct answer as this equatorial trough is called the monsoon trough.

What is 'mahawat'?

  1. It is winter rainfall.

  2. It is the pre-monsoon shower.

  3. It is the advancing monsoon.

  4. It is the retreating monsoon.

  5. It is the localised thunderstorm during the winter season.


Correct Option: A
Explanation:

This is the correct answer as winter rainfall is locally known as ‘mahawat’.

Which of the following statements is/are correct?

a. Fast flowing and narrow air currents are called jet streams. b. The westerly jet streams are responsible for western cyclonic disturbances in the north and north-western parts of India. c. The easterly jet stream moves north of the Himalayas with the apparent movement of the sun.

  1. a only

  2. b only

  3. c only

  4. a and b

  5. a and c


Correct Option: D
Explanation:

This is the correct answer as both statements are correct.

Why is the delta region of the eastern coast frequently struck by cyclones?

  1. Because the Bay of Bengal is the centre of various pressure changes

  2. Because the pressure changes in Arabian sea travel east and cause cyclonic disturbances

  3. Because of the movements of low pressure conditions in the Bay of Bengal

  4. Because low-pressure conditions over the northern plains attract the trade winds from the southern hemisphere

  5. Because high-pressure systems that originate over the Mediterranean Sea and Western Asia and move into India


Correct Option: A
Explanation:

This is the correct answer. The Bay of Bengal is the centre of various pressure changes and hence, there is always a chance of development of cyclonic disturbances.

Which of the following areas in India receive less than 10 cm rainfall?

a. Andaman and Nicobar Islands b. Meghalaya c. Ladakh d. Western Rajasthan

  1. a, b, c and d

  2. a, b and c

  3. a, c and d

  4. a and d

  5. c and d


Correct Option: E
Explanation:

This is the correct answer as Ladakh and western Rajasthan receive less than 10 cm rainfall.

Which of the following statements is/are correct?

a. The Bay of Bengal branch of the monsoon reaches Assam around mid June. b. Delhi generally receives the monsoon showers from the Bay of Bengal branch by the end of June. c. The monsoon withdraws completely from India around mid october.

  1. a only

  2. b only

  3. c only

  4. a and b

  5. b and c


Correct Option: B
Explanation:

This is the correct answer as this statement is correct.

Which of the following statements is/are correct?

a. As the distance from the sea increases, its moderating influence decreases, which is called continentality. b. As one goes from the surface of the earth to higher altitudes, the atmosphere becomes less dense and temperature decreases, which is called Ferrel's law. c. The way ocean currents along with onshore winds affect the climate of the coastal areas is called Coriolis force.

  1. a only

  2. b only

  3. c only

  4. a and b

  5. b and c


Correct Option: A
Explanation:

This is the correct answer.

How does latitude affect the temperature of a place?

  1. The higher the area, the cooler the place.

  2. The curvature of the earth affects temperature.

  3. The Coriolis force is affected by the latitude.

  4. The latitudes affect the cyclonic disturbances.

  5. All of the above


Correct Option: B
Explanation:

This is the correct answer as due to the curvature of the earth, the amount of solar energy received varies according to latitude. As a result, air temperature generally decreases from the equator towards the poles.

Which of the following is/are correct about the seasonal reversal of wind direction over the Indian subcontinent?

a. As the monsoon winds move towards west, their moisture content tends to reduce with subsequent rains which causes the seasonal reversal of wind direction. b. The pressure differential such as El Nino causes the seasonal reversal of wind direction over the Indian subcontinent. c. The broad trough of low pressure in the equatorial ITCZ causes the seasonal reversal of wind direction over the Indian subcontinent.

  1. a only

  2. b only

  3. c only

  4. a and c

  5. None of these


Correct Option: B
Explanation:

This is the correct answer as the pressure differential such as El Nino causes the seasonal reversal of wind direction over the Indian subcontinent.

A phenomenon associated with the monsoon is its tendency to have ‘breaks’ in rainfall. Why do these breaks happen?

  1. An elongated low-pressure area develops extending from the Thar Desert in the northwest to Patna and Chotanagpur plateau in the east and southeast causing troughs that cause breaks.

  2. The southeast trade winds blow in a south westerly direction causing troughs that cause breaks.

  3. When the axis of the monsoon trough lies over the plains, monsoon breaks occur.

  4. The tropical depressions over Bay of Bengal cause monsoon breaks over the northern plains.

  5. The movement of the monsoon trough and its axis keeps on moving northward or southward causing spatial distribution of rain.


Correct Option: E
Explanation:

This is the correct answer. This spatial difference of rainfall is called monsoon break when it is interspersed with rainless intervals.

Which of the following statements is/are incorrect?

a. Localised thunderstorms during the winter months in the southern part of the country are called Kaal Baisakhi. b. Pre-monsoon showers help in early ripening of mangoes and are called mango showers in Uttar Pradesh and West Bengal. c. The strong, gusty, hot and dry winds blowing during the day over north and northwestern India are called loo.

  1. a only

  2. b only

  3. c only

  4. a and b

  5. b and c


Correct Option: D
Explanation:

This is the correct answer as both the statements are incorrect. The localised thunderstorms associated with violent winds, torrential downpours, often accompanied by hail, are known as ‘Kaal Baisakhi' in West Bengal. Pre-monsoon showers in Kerala and Karnataka help in the early ripening of mangoes, and are often referred to as mango showers.
