Question 1

Consider the following statements relative to Air Density and select the one which is correct:

Answer 1

At any given surface temperature the air density will be greater in anticyclonic conditions than it will be when the MSL pressure is lower.

Question 2

The tropopause in mid latitudes is:

Answer 2

Lower in winter with a higher temperature.

Question 3

Generally as altitude increases:

Answer 3

temperature, pressure and density decreases
