Question

Illustrate an example to show that high speed wind reduces air pressure

Answer 1

Example:

take two balloons of approximately same size and put little water into them,to make them heavy.inflate each of the balloons and suspend them from some fixed support such as rod.so the balloons are 10 cm apart from each other.now take a cardboard sheet and roll it like a tube,holding the tube close to the gap between two balloons blow hard.we observe the freely suspended balloons move together.

Reason:when high speed air moves through the gap in between the balloons the pressure of air falls in the gap.thus the air at the higher pressure on the side of balloon forces them inward
