4. How does a depression form? The stages the formation of a depression

5. Stage 1 Pm Tm Polar air travels towards tropical air

6. Stage 2 Pm Tm Cold polar air starts to cut under the lighter, warm tropical air making it rise. The rising air creates a low pressure on the ground

7. Stage 3 Pm Tm A spinning depression is formed with a warm front and a cold front. Winds always spin anticlockwise.

8. Stage 4 Pm Tm The depression starts to die as the warm air is forced to rise

9. Stage 5 A dead depression. Winds die down (isobars spread apart) and the rain stops
