Note: When using annual hourly meteorological data to study the actual occurrence and duration of the steady-state weather conditions, steady-state weather condition marked as stability with wind speed (F1, F3, etc.) represented the weather condition with certain stability class and the wind speed equal or less than certain value and any other conditions that are more stable than the indicated condition
