- Press Play the passage on the cold front and watch pressure, temperature and wind direction change at the station.
- Switch to the warm front and count the cloud sequence as the front gets closer: Ci, Cs, As, Ns.
- Use Just before and Just after to compare the weather on each side of the front.
Exam point
Cold front: steep slope, narrow band of Cb, sharp veer and a sudden pressure rise. Warm front: shallow slope, long cloud sequence, steady rain, then a veer and the temperature jumps. The wind veers as a front passes in the northern hemisphere.
