2.3.4
Occlusion process and associated weather
An occlusion occurs when a cold front catches up with a warm front at the
centre of the mid-latitude cyclone (2)
This is due to the cold front moving faster than the warm front as it is cold and
dense air (2)
This forces all warm sector air off the surface (2)
This results in cool and cold air masses behind the cold front and in front of the
warm front (2)
The coldest of these air masses forces the cool air to rise resulting in light
showers (2)
Thereafter the fronts collapse (2)
