• Cumulonimbus clouds will most likely develop at A.
• Light rain can be expected at B because warm air gradually rises above the cooler air
masses.
• The occlusion front depicted in diagram C is a cold occlusion.
• The occlusion in diagram C is the result of cold air moving faster than warm air.
The process during the disintegration stage of a mid-latitude cyclone. (@_ 2020)
➢ The cold front moves faster than the warm front and overtakes it.
➢ This displaces warm sectors higher up in the atmosphere.
➢ The cold air behind the cold front must be colder than the cold air in front of the warm front.
➢ Finally only cold and cool air at ground level

Mid-latitude cyclone X(@_ 2022)
Did you know?
Mid-latitude cyclones
typically have a diameter of
about 1,000–3,000 km.
The evidence on the synoptic weather map indicates that X is a mid-latitude cyclone.
❖ Presence of fronts
❖ Presence of an occlusion
The stage of development of mid-latitude cyclone X
❖ Occlusion/dissolution stage because the cold front and warm front have merged
Evidence from the synoptic weather map that winter conditions are indicated.
❖ Cold front west of South Africa
❖ Mid-latitude cyclone affects SA's weather
