why does the air pressure drop during a hurricane?

Answer 1

The reason why is that in order for a storm to develop you need low or dropping pressure. The pressure drop occurs as water vapor within the storm condenses into water droplets and releases latent heat into the atmosphere. Latent heat is defined as the energy released when a substance changes phases, such as gas to liquid in this case.

The addition of heat causes atmospheric gases to expand, so the air inside the depression becomes less dense and rises tens of thousands of feet above the ocean surface. As its altitude increases, the air cools causing more water vapor to condense and release its heat, which draws in yet more air to rise upward. This process repeats itself again and again causing the temperature at the center of the storm to continually increase and driving the surface pressure even lower. As the pressure drops, more low-altitude air that is rich in water vapor is pulled inward to release yet more heat into the center of the storm.
