Final answer:
The value given for probability of tornadoes represents the likelihood of a tornado occurring in a specific location and time. This probability may vary by geographic region due to differences in atmospheric conditions. Severe winds and hail have higher probabilities than tornadoes due to their frequency in severe thunderstorms.
Step-by-step explanation:
In the context of tornadoes, the value given for probability represents the likelihood of a tornado occurring at a specific location and time. It is a numerical measure of the chances of a tornado forming in an area within a given timeframe. The probability of tornadoes may vary by geographic region due to differences in atmospheric conditions that contribute to tornado formation.
The probabilities for severe winds and hail are typically greater than tornadoes because these phenomena are more common in severe thunderstorms. Severe winds and hail can be associated with strong updrafts and downdrafts in the thunderstorm, which create turbulent winds and cause hailstones to form. Tornadoes, on the other hand, require a specific combination of atmospheric conditions to form and are less frequent.
