For a surface low-pressure center to exist for an extended period, what condition must exist aloft?
 
  What will be an ideal response?

Question 2

Briefly describe how the Coriolis effect influences air movement.
 
  What will be an ideal response?

Answer to Question 1

In order for a surface low-pressure center to exist for an extended period, divergence (spreading out) aloft must be occurring at a rate equal to the inflow below.

Answer to Question 2

As air moves out of regions of higher pressure into regions of lower pressure, it is also deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is due to the Coriolis effect.
