At the Earth’s surface, air generally converges and rises over a low-pressure area. Over a high-pressure area, air subsides from above and diverges at the surface.

Which one of the following conclusions follows most appropriately?

  1. Surface divergence over a high-pressure area is the principal mechanism producing widespread uplift and precipitation.
  2. Air rises over a low-pressure area only when the Coriolis force is absent.
  3. Low-pressure convergence favours cloud formation and precipitation by promoting the upward movement of air.
  4. Surface pressure systems are unrelated to wind circulation at higher atmospheric levels.
