Important Questions on Climatology
Which of the following is the reason for Atmospheric circulation in the form of cells?
1. Due to disturbances in the planetary pressure system
2. Vertical circulation cell
The loss of water vapour by plants after it has been drawn from the soil is called
Consider the following climatic and geographical phenomena
1. Condensation
2. High temperature and humidity
3. Orography
4. Vertical wind
Thunder cloud development is due to which of these phenomena?
Assertion (A) 60°-65° latitudes in both the hemispheres have a low pressure belt instead of high pressure.
Reason (R) The low pressure areas are permanent over oceans rather than on land.
Codes
High temperatures before rains, the skies are clear and circulation is anti-cyclonic is characteristic of
Assertion (A) Anti-cyclonic conditions are formed in winter season when atmospheric pressure is high and air temperatures are low.
Reason (R) Winter rainfall in Northam India causes development of anticyclonic conditions with low temperatures.
Codes
Assertion (A) In Stratosphere the temperature increase with altitude results in a layering effect.
Reason (R) It creates a global 'inversion layer', and reduces vertical convection.
Codes
Consider the following statements regarding lapse rate
1. An unsaturated air mass cools at dry adiabatic lapse rate when it rise in the atmosphere.
2. The dry adiabatic lapse rate amounts to 1°C per 100m.
3. The wet adiabatic lapse rate may vary between 0.4°C and 0.9°C per 100m.
4. Dry adiabatic lapse rate is higher because of the release of latent heat of condensation.
Which of the above given statements are correct?
Choose the correct statement
1. Purga is snow laden cold wind in Russian Tundra.
2. Bise is an extremely cold wind in France.
3. Yamo is warm and dry wind in Japan.
4. Santa Ana is warm and dry wind in Argentina.
Codes
A Mediterranean climate is characterised by very dry summers because
Consider the following statements
1. Nearly of the total mass of the atmosphere lies within of the Earth's surface.
2. The proportion of ozone in the atmosphere increases to a maximum at about 60 km from Earth's surface.
Which of the statements given above is/ are correct?
All of the following types of climate occur in the Southern hemisphere except
Assertion (A) The annual range of temperature is less in the equatorial region as compared to the sub-tropical or temperate region.
Reason (R) In the equatorial region, the rainfall occurs all round the year.
Codes
Match List I with List II and select the correct answer using the code given below the lists.
| List (Climate) | List (Characteristic) |
| A. Mediterranean | 1. Temperature cycle is moderated by marine influence |
| B. Marine West coast | 2. Warm summers and cold winters with three months below freezing. Very large annual temperature range |
| C. Dry mid - latitude | 3. Strong temperature cycle with large annual range. Warm summers to hot and cold winters to very cold |
| D. Moist continental | 4. Temperature range is moderate with warm to hot summers and mild winters |
Codes
Which one of the following sets are the low clouds?
When is fog formed?
Assertion (A) There would be no monsoon if the earth's surface were composed of either land or all water.
Reason (R) Monsoons are to a large extent, the result of differential heating of the land and water.
Codes
Which of the following is true?
What is the name of the winds that blow from the subtropical high pressure belts towards the subpolar low pressure belts?
Which one of the following is the pattern of circulation around a low - pressure area in the Northern hemisphere
