What are the impacts of meteorological drought?
Drought affects the level of precipitation, groundwater storage, and the availability of soil moisture. It can lead to water shortages, affecting agricultural and hydro energy production, environmental quality, and human well-being (Hisdal & Tallaksen 2003).
What is the difference between meteorological and agricultural drought?
Meteorological drought is the result of deficiencies in precipitation. Agricultural drought is an effect of various characteristics of meteorological and hydrological drought in agriculture comprising the reduction of evapotranspiration, soil water deficits, and reduced crop yield.
What means meteorological?
1 : a science that deals with the atmosphere and its phenomena and especially with weather and weather forecasting studied the principles of meteorology. 2 : the atmospheric phenomena and weather of a region the meteorology of the Gulf of Mexico.
What is contingent drought?
Contingent drought: This involves an abnormal failure of rainfall. It may occur almost anywhere especially in most parts of humid or sub humid climates. … When rainfall is inadequate to meet the evapo-transpiration losses, the result is borderline water deficiency in soil resulting in less than optimum yield.
Definition of Drought Drought is a period of below-average precipitation in a given region, resulting in prolonged shortages in its water supply, whether atmospheric, surface or ground water. A drought can last for months or years, or may be declared after as few as 15 days.
How can meteorological drought be triggered by physical?
It is more than just a moisture deficit, however. It is the result of a complex interplay between natural precipitation deficiencies on varying time and space scales and can be exacerbated by human water demand and inefficiencies in water distribution and usage.
