Answer
The term that describes air movement towards area B is 'convergence.' This occurs as air flows into the low-pressure center of the cyclone.
Step 5

Answer
At B, air moves towards a zone of low pressure because of the pressure gradient created by the surrounding high-pressure areas, causing the air to descend and converge.

Answer
The tropical cyclone experiences the lowest pressure in the eye of the cyclone, which is the central part where calm and clear conditions prevail.

Answer
Air descends in area B due to the cooling effects resulting from the air diverging away from the low-pressure area, leading to subsidence and clearing conditions.
