Wind is moving air that is caused by differences in air pressure inside our atmosphere. The air below high pressure moves toward areas of low pressure. The greater the variation in pressure, the quicker the air runs.
When there is a great difference in air pressure between two areas, winds are strong. The air moves from high pressure to low pressure, causing faster winds to equalize the pressure difference.

Change in air pressure causes the strong winds. In fact, most winds that we experience on Earth are caused by change in air pressure. Usually significant changes in air pressure occur over a large area and therefore it's only a slow change in pressure over distance making light winds. In a tornado, you get a significant drop in air pressure over just a few feet of land. This causes the winds to get excessivly high.
The primary cause of winds is the uneven heating of the Earth's surface by the sun. This causes differences in air pressure, which then leads to the movement of air from high pressure to low pressure areas, creating wind.
A low air pressure in a storm can cause strong winds as air rushes from areas of high pressure to low pressure. It can also lead to storm surge, as the displaced air pushes water towards the coast. Additionally, low pressure can result in heavy rainfall and potential flooding.
The air pressure differences result mostly from the uneven heating of earth's surface.
As the air pressure dropped, the winds picked up and the weather turned foul.
No. It was once believed that the low pressure inside a tornado would cause houses to explode, but this notion was disproven by the 1990s. It is the wind and debris in a tornado that destroys houses, not the low pressure.
The low pressure inside a tornado pulls air inward. This air accelerates to great speeds as it enters the tornado, though due to the spin not much of the air actually reaches the center. Generally lower pressure means faster winds, and thus more potential for damage.
High winds at a beach can cause strong currents, rough surf, and blowing sand. These conditions may pose risks to swimmers and water activities, increase erosion of the beach, and create challenging conditions for sunbathing or picnicking.
