Final answer:
The inside of a tornado funnel has low atmospheric pressure, contributing to the tornado's ability to cause extensive damage and to reach wind speeds up to 500 km/h. A significant pressure difference between the interior of the funnel and the surrounding atmosphere is characteristic of tornado formation.
Step-by-step explanation:
The answer to the question is low atmospheric pressure. The inside of a tornado funnel has low atmospheric pressure which is a key factor in tornado formation. As wind speeds increase and air rapidly circulates, the pressure inside the funnel drops significantly compared to the surrounding air. This pressure difference is what allows the tornado to pick up debris and cause the extensive damage tornadoes are known for.Tornadoes are associated with severe weather conditions and can reach wind speeds as high as 500 km/h, especially near the bottom of the funnel where the radius is smallest, and therefore wind speeds are greatest. The rising motions within thunderstorms coupled with variations in wind speed and direction with height, create an environment conducive to the development of tornadoes. The lower pressure inside the funnel relative to the atmospheric pressure outside is critical for the formation and sustainability of the destructive power of a tornado.In conclusion, storm reports typically show that regions with lower atmospheric pressure are often susceptible to severe weather phenomena like tornadoes. The pressure inside the tornado funnel is significantly lower than the ambient atmospheric pressure, which contributes to the tornado's capability to cause damage.
