Determining when drought develops is a function of drought impacts and water users. Drought is best sought as a period of dry weather, and extended shortage of water, especially a long one that is injurious to crops. This is a dangerous hydrologic condition that not only concerns water users in the affected area but also in some other locations some water users exempt but not all the way safe. Drought is a abnormal circumstance if it is insistent. Drought is a gradual emergency. This means it is not the typical natural disaster that you cannot prepare for because of the rapid pace. There is neither a real explanation nor time frame on when a drought begins and ends. Signs of drought can be anywhere from …show more content…
The boundless number of rainfall and stream flow data started during the turn of the 20th century. The recorded hydrology during this time period only collected a few significant statewide droughts that manifested. These historical droughts occurred during 1928-34, 1976-77, 1987-92, and 2007-09. The latest heavy regional drought that shook the Southern parts of California was during 1999-2002. According to historical data with estimates from implied signals such as tree rings that suggest that the 1928-34 case may have been the most impacted driest period in the Sacramento, California River watershed since the mid 1550s. Now it is questioned whether the causes of California drought is linked to climate change, or even man-made. The severe atmospheric conditions joint with California’s drought occurrence are far more likely to appear with today’s global warming that have not existed before California citizens relied on the large amount of greenhouse gases. Combinations of unusual warm temperatures for California weather and stagnant air conditions, the loss of precipitation has produced a dangerous uproar with incidents relevant to air pollution, wildfires, and increased evaporation. The high increase in evaporation rates gradually lead to greater drying of soils and vegetation, having the potential to affect the natural land-based and manage ecosystems, coastal systems, and both …show more content…
The storms following this path is determined through the location of an atmospheric high pressure belt that most often shifts toward the south during the winter season, permitting low pressure zones to move in and around the state. The state of California on average, 75 percent of annual precipitation occurs from November through Mach, with 50 percent occurring from December through February. This average is dependent on a comparatively small number of storms. Various storms more or less during the winter season can possibly determine if the year will continue to be wet or dry. If this remains constant Pacific high-pressure zone will continue over in mid-winter, there is a leaning chance for the year to be
