Question

Why does arctic air resist rising more than tropical air does?

Answer 1

Hot air is lighter, and rises. Cold air is more dense, and it does not rise. This is why hot air balloons work.

Answer 2

thats because on warmer temperature the pressure becomes lower so that the particles of air will be easily rise..cause of the lower density

while at colder temperature.. air pressure become very high.. so it is difficult for air particles movement and rise.

Answer 3

Ascent of air in the atmosphere is called convection.Convection will take place only if the ascending air is warmer than the surrounding air.In tropics, the amount of solar radiation received is more than that at poles throughout the year and hence convection takes place on a large scale reaching greater heights.In the north pole convection takes place on a small scale only and hence air does not reach more heights.

Moreover the height of tropopause over the pole is almost half that of the equator.Air cannot rise above tropopause as convection is prevented by the fact that atmosphere is stable there due to rise of temperature with height.

Answer 4

yes be it's close to the poles and gravtion pulles it down.
