GEOG 2050 : Final Study Guide [Completed]
Document Summary
The restless sky: storm systems and el ni o. This chapter provides an overview of storm systems in the atmosphere. Storm systems are arranged by their spatial extent, from local phenomena, such as single-cell thunderstorms, up to synoptic-scale events like hurricanes and midlatitude cyclones. El ni o also forms a significant unit in this chapter. Worldwide, most thunderstorms occur in the tropics over land. Equatorial africa has the highest thunderstorm frequency in the world. Thunderstorms are discussed in the order of their spatial extent. Multicell thunderstorms can bring severe weather and are embedded along fronts that persist for hours to days. Supercell thunderstorms are the strongest of thunderstorms and have a rotating internal core. They always produce severe weather and sometimes they produce tornadoes. The two main hazards of thunderstorms are lightning and tornadoes. Outdoor lightning safety includes avoiding being on or near the highest points in a landscape and retreating indoors whenever possible.
