21.   These strong pressure differences produced the fierce winds.

22.   They then use Bernoulli to calculate the pressure difference between the top and bottom of a wing.

23.   This leads to strong pressure differences at high altitudes.

24.   This past weekend, weak low pressure south of Hawaii combined with high pressure to the north to enhance the pressure difference that energizes the tropical trade winds.

25.   Typically, the pressure differences between areas of high and low pressure are responsible for strong winds across large areas.
