Document Summary
Earth science catastrophic events long answers: cyclonic storms. Define front: the boundary between two air masses of different temperatures. If the air is moist and unstable, thunderstorms will form along the cold front: moist air is less dense than dry cool air and therefore will be lifted quicker. What parameters are used to measure hurricane intensity: saffir- simpson hurricane scale, wind speed, surface pressure, storm surge. Describe all the conditions essential for successful development of a hurricane north of the equator and in the atlantic ocean: hurricanes need warm tropical oceans that have surface temperatures of. Needs low vertical wind shear, especially in the upper level of the atmosphere. Moisture and light winds above them: needs high relative humidity values from the surface to the mid levels of the atmosphere xi. Needs saturated lapse rate gradient near the center of rotation of the storm. A saturated lapse rate insures latent heat will be released at a maximum rate xiii.
