the energy absorbed by or released from a substance during a phase change. Associated Weather - thunderstorms, hurricanes Latent Heat
a region of mostly calm weather at the center of strong tropical cyclones. Associated Weather - hurricanes Eye
a rising of the sea as a result of atmospheric pressure changes and wind associated with a storm. Formation - powerful wind whips up huge waves. Associated Weather - hurricanes Storm Surge
scale measuring hurricanes - categories 1-5 (lowest to highest) Saffir-Simpson Scale
