The terms "F0, F1, F2, ..." refer to a classification system used to categorize tornadoes based on their intensity and damage potential. This scale, known as the Fujita Scale, ranges from F0, which indicates light damage, to F5, which signifies incredible damage. Each category reflects the estimated wind speeds and the resulting destruction to structures and vegetation. The Enhanced Fujita Scale (EF Scale) is a more recent version that refines the original Fujita Scale. It also uses a similar classification system, ranging from EF0 to EF5, providing a more accurate assessment of tornado damage. This helps meteorologists and researchers better understand tornado impacts and improve safety measures.
