Hurricane Effects and Wind Scales

The video explains the Beaufort and Saffir-Simpson scales used to measure wind strength. It details the Saffir-Simpson scale, which categorizes hurricanes from Category 1 to 5 based on wind speed and potential damage. Category 1 hurricanes have winds of 119-153 km/h, causing minor damage. Category 2 hurricanes have winds of 154-177 km/h, causing more significant damage and power outages. Categories 3 to 5 are major hurricanes, with increasing wind speeds and catastrophic damage, including structural destruction and long-term power outages.

What is the main limitation of the Beaufort scale?

• It is only used for measuring ocean currents.

• It only measures wind direction.

• It is not applicable to extremely strong winds like hurricanes.

• It cannot measure wind speeds below 10 km/h.
