Best Answer: Tornadoes are caused by winds. When a tornado forms the wind pressure around the tornado drops and that's what you see on the barometer, the pressure goes down.
Air pressure changes with the weather. In fact, it's one of the most important factors that determines what the weather is like. (Related: How high and low pressure affect the weather). You can do some basic weather forecasting by using the wind and barometric pressure.(Related: Using pressure, wind for forecasts).ir pressure changes with the weather.
