The term storm is usually applied to any violent atmospheric disturbance and covers a range of meteorological systems, from low-pressure depressions and thunderstorms to hurricanes, typhoons and tropical cyclones. Storms are commonly associated with fierce winds. In addition, storms are often multi-hazard, including other hydrometeorological phenomena and hazards such as precipitation and storm surges (chapter 7), leading to flooding, lightning and rain-induced landslides (chapter 5).
