What percent of short wave solar radiation is reflected by clouds?

  1. 6

  2. 14

  3. 17

  4. 27

The phenomenon of inversion of temperature is usually seen in the nights of which of the following seasons?

  1. Summer

  2. Spring

  3. Autumn

  4. Winter

  5. Throughout the year


Correct Option: D
Explanation:

A long winter night with clear sky and still air is ideal situation for inversion. The heat of the day is radiated off during the night, and by early morning hours, the earth is cooler than the air above. Over polar areas, the temperature inversion is normal throughout the year.

Which of the following statements about isotherms is correct?

  1. Isotherms always remain parallel to the latitude.

  2. In January, isotherms deviate to the south over the ocean and to the north over the continent.

  3. In January, isotherms deviate to the north over the ocean and to the south over the continent.

  4. In January, isotherms deviate to the north over the ocean and to the south over the continent especially in the northern hemisphere.

  5. In January, isotherms deviate to the north over the ocean and to the south over the continent especially in the southern hemisphere.


Correct Option: D
Explanation:

In the northern hemisphere the land surface area is much larger than in the southern hemisphere. Hence, the effects of land mass and the ocean currents are well pronounced. In January, the isotherms deviate to the north over the ocean and to the south over the continent.
