They occur, as a rule, because of lack, insufficiency, or inadequate distribution of precipitation. The approach in the context of meteorological drought is objective, but the assessment of drought is relative.

Drought is thought by some to have caused migrations of early humans. In India and China drought has periodically brought widespread privation and death. In lack of rainfall devastated the Great Plains of the United States; called the Dust Bowl, its area spread to alarming dimensions (about 50 million acres). Meteorological drought is the basis of agricultural drought. The Standardized Precipitation Index (SPI) (Hayes et al., ) is a traditional meteorological drought comparing SPI and ADI in three regions, we found that the correlation between SPI and ADI was very significant, which indicated that ADI was consistent with the meteorological drought index in drought intensity ().Cited by: 8.

A drought or drouth is an event of prolonged shortages in the water supply, whether atmospheric (below-average precipitation), surface water or ground water.A drought can last for months or years, or may be declared after as few as 15 days.

It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. Drought Persists in the American Southwest. More than 64 million people are directly affected by drought in the Southwest and Southern Plains, and far more are indirectly affected because of the vast number of farms, orchards, and ranches that supply the rest of the United States.

Image of the Day Land Life Water Drought. Drought is a prolonged dry period in the natural climate cylce that can occur anywhere in the world. It is a slow on-set phenomenon caused by a lack of rainfall. Compounding factors, such as poverty and inappropriate land use, increase vulnerability to drought.

When drought causes water and food shortages, there can be many impacts on the health of the population, which may. Understanding the Drought Phenomenon: The Role of Definitions.

Drought in the Southwest. Prolonged dry conditions are a natural part of life in the Southwest. Past records from tree-rings indicate that the Southwest has experienced protracted “mega” droughts that lasted about 50 years, a duration unlike the s and s droughts that caused economic losses to agriculture, ranching, industry and many other sectors.

Therefore, for the present study, the analysis of the drought has been divided into: meteorological, hydrological and agricultural drought (Fig. The Meteorological or Climatological Drought Is the prolonged absence of precipitation.
