Funnel Cloud - A rotating column of air extended down from a cloud but not touching the ground. The trapping of heat energy inside of the Earth. Gust Front - Wind flowing out from a thunderstorm. Gust fronts sometimes create very strong surface winds as a result of a temperature change as the front passes. An area of high atmospheric pressure.
Highs generally create cooler, dryer temperatures, with little or no clouds.
Hurricane - A tropical cyclone with wind speeds in excess of 74 miles per hour. I Iridescence - Colorful patches in clouds caused by sunlight passing through the water droplets. K Knot - A unit of measuring for speeds of ships and is used in meteorology for wind speed. All meteorologists currently use knots for plotting wind speed on weather maps. L Latent Heat - Heat released into the air when water vapor condenses and forms clouds.
