Multiple choice

For preparation of weather maps, which of the following reasons is correct, for measuring air pressure at station level after reducing it to sea level?

  1. Because of the effect of wind in denser gravity

  2. For adjusting variations caused by air motions

  3. Because of the vertical pressure exerted by gradient forces

  4. For eliminating the effect of altitude

  5. For eliminating the effect of turbulent wind patterns and air masses

D Correct answer
Explanation

In order to eliminate the effect of altitude on pressure, it is measured at any station after being reduced to sea level for purposes of comparison. Thus, this is the correct answer.
