The historical and ongoing droughts in California result from various complex meteorological phenomena, some of which are not fully understood by scientists. Drought is generally defined as “a deficiency of precipitation over an extended period of time (usually a season or more), resulting in a water shortage.” There are five major categories of drought: (1) Meteorological, (2) Agricultural, (3) Hydrological, (4) Socioeconomic, and (5) Ecological. A meteorological drought may be short lived without causing disturbance; but when longer lasting may enter other categories according to its impacts.
