Understanding Storm Intensity
Storm intensity is a measure of a storm’s strength and its potential impact. Several factors are used to determine how powerful a storm is and to categorize it appropriately.
How Storms are Measured
Storms are measured using various metrics such as wind speed, pressure, and storm surge. Wind speed is one of the primary indicators and is recorded in miles per hour (mph). Pressure, measured in millibars, helps gauge the storm’s intensity—lower pressure usually means a stronger storm.
Storm surge refers to the rise in sea level due to the storm’s winds pushing water inland. This can lead to severe flooding. Instruments like barometers and anemometers are used to collect data. Satellites also provide vital imagery for tracking storm development and intensity.
Categories and Scales
Hurricanes are categorized using the Saffir-Simpson Hurricane Wind Scale. This scale ranges from Category 1 to Category 5, with Category 5 being the most intense.
Each category measures sustained wind speeds:
- Category 1: 74-95 mph
- Category 2: 96-110 mph
- Category 3: 111-129 mph
- Category 4: 130-156 mph
- Category 5: Over 157 mph
Another scale is the Beaufort Wind Force Scale, used to describe wind intensity.
Tornadoes, although not hurricanes, are also crucial to understand. They are measured by the Enhanced Fujita (EF) Scale, which ranges from EF0 to EF5 based on the damage they can cause.
Each scale serves to provide standard measurements that help in forecasting and emergency response planning.
