Dew Point - The temperature to which the air must be cooled to condense.
For example, if the air temperature was 65 ° and the dew point was 65
° the humidity would be 100% and the air would be totally saturated.
The larger the spread of temperature and dew point, the drier the air. This
spread is called the dew point depression.
Saffir-Simpson Scale
The Saffir-Simpson Hurricane Scale rates a hurricane's intensity using wind
speed and storm surge, which is the abnormal rise in sea level accompanying
a hurricane or other intense storm. The scale also estimates the potential
damage and flooding expected along the coast from a hurricane landfall.
-
Category One Wind speed: 74-95 mph (119-153 km/h) Storm surge: 4-5 feet above
normal
-
Category Two Wind speed: 96-110 mph (154-177 km/h) Storm surge: 6-8 feet
above normal
-
Category Three Wind speed: 111-130 mph (178-209 km/h) Storm surge: 9-12 feet
above normal
-
Category Four Wind speed: 131-155 mph (210-249 km/h) Storm surge: 13-18 feet
above normal
-
Category Five Wind speed: Greater than 155 mph (249 km/h) Storm surge: generally
greater than 18 feet above normal
