Monohar Pandey Solutions for Exercise 4: Exercise 4

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

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?

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

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

High temperatures before rains, the skies are clear and circulation is anti-cyclonic is characteristic of

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

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?

The loss of water vapour by plants after it has been drawn from the soil is called
