Detailed explanation-1: -A drought is defined as “a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the affected area.”-Glossary of Meteorology (1959).

Detailed explanation-2: -Drought is the absence of precipitation, rather than the presence of an event such as a hurricane, tornado, or fire. It’s often described as a “creeping phenomenon” because it slowly impacts many sectors of the economy and operates on many different timescales.

Detailed explanation-3: -A drought is a period of time when an area or region experiences below-normal precipitation. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater, diminished stream flow, crop damage, and a general water shortage.

Detailed explanation-4: -Drought is a long period without rains leading to a severe shortage of water in the region. The soil continues to lose water by evaporation and transpiration. If, however, it does rain at all or the rainfall is very low for a long period, the loss of water from the soil is not made up and hence the soil becomes dry.
