9.9 The surface position of the stationary front does not move or moves very slowly because:
The winds on both sides of the front are calm.
The winds blow parallel to the front.
The front is located between a cyclone and an anticyclone.
The winds blow against each other and are of equal strength.
The winds blow in the direction of the warm air mass.

9.18 Speed divergence in the upper atmosphere has what effect on cyclogenesis?
It either inhibits or enhances cyclogenesis, depending upon surface temperature.
It inhibits cyclogenesis by preventing cyclonic flow.
It enhances cyclogenesis by increasing convergence at the surface below.
It has no impact on the formation of midlatitude cyclones.
