Step-by-step explanation:
1. The season represented on the synoptic weather map is not explicitly mentioned in the provided text. Without additional information or context, it is difficult to determine the season from the given extract.
2. The stage of development of mid-latitude cyclone C is not specified in the provided text. Without further details or visuals of the synoptic map, it is challenging to identify the specific stage of development.
3. Since the stage of development for cyclone C is not mentioned, there is no evidence available from the synoptic map to support an answer for question 1.3.2.
4. The information about which mid-latitude cyclone (A, B, or C) is the oldest is not provided in the given text or extract. Without additional details, it is not possible to determine which cyclone is the oldest.
5. The provided text does not contain any information about the change in temperature, wind direction, and cloud cover as the cold front of mid-latitude cyclone A approaches Cape Town. Therefore, it is not possible to answer question 1.3.5 with the given information.
