Question 1

Question
1. The measurement of surface temperature is made:
Answer
  • a) At ground level.
  • b) At approximately 10 metres above ground level.
  • c) At approximately 4 feet above ground level.
  • d) At approximately 4 metres above ground level.

Question 2

Question
2. Cloud cover will reduce diurnal variation of temperature because:
Answer
  • a) Incoming solar radiation is reflected back to space and outgoing terrestrial radiation is reflected back to earth.
  • b) Incoming solar radiation is re-radiated back to space and atmospheric heating by convection will stop at the level of the cloud layer.
  • c) The cloud stops the sun rays getting through to the earth and also reduces outgoing conduction.
  • d) Incoming solar radiation is reflected back to space and outgoing terrestrial radiation is re-radiated from the cloud layer back to the surface.

Question
3. Most accurate temperatures above the ground level are obtained by:
Answer
  • a) Tephigram.

Question 4

Question
4. The diurnal variation of temperature is:
Answer

Question 5

Question
5. Over continents and oceans, the relative temperature conditions are:
Answer
