Measuring Tornadoes

                 Tornadoes are measured by many tools. One tool is built especially for tornadoes. It is called a turtle. Turtles measure the wind speed, wind direction, temperature, humidity, and air pressure. How turtles are used are that they are placed in an area a tornado is striking, and when a tornado runs over a turtle, the turtle then measures it.
       
                 Barometers are also used to measure these powerful funnels. Barometers measure air pressure. This measures the power of tornado because the lower the air pressure, the more severe the tornado is.

                  A scale called the Enhanced Fujita scale, also known as the EF scale, measures the deadliness of a tornado. The Enhanced Fujita scale measures tornadoes based on their wind speed. This scale ranks tornadoes from F1 to F5. F1 is the least powerful, while F5 is the most powerful.
