I. An unsaturated air mass cools at dry adiabatic lapse rate when it rise in the atmosphere.
II. The dry adiabatic lapse rate amounts to 1°C per 100 m.
III. The wet adiabatic lapse rate may vary between 0.4°C and 0.9°C per 100 m.
IV. Dry adiabatic lapse rate is higher because of the release of latent heat of condensation.

The thunder cloud development is due to which of these phenomena?

I. Normal El Niño forms in the Central Pacific Ocean, whereas El Niño Modoki forms in Eastern Pacific Ocean.
II. Normal El Niño results in diminished hurricanes in the Atlantic Ocean, but El Niño Modoki results in a greater number of hurricanes with greater frequency.
Which of the statements given above is/are correct?

I. They are strong Westerly winds found in the oceans of Southern Hemisphere.
II. The strong East to West air currents are caused by the combination of air being displaced from the Equator towards the South Pole and the Earth’s rotation and abundance of landmasses to serve as wind breaks.
