Detailed explanation-1: -Drought is an extended period of unusually dry weather when there is not enough rain. The lack of precipitation can cause a variety of problems for local communities, including damage to crops and a shortage of drinking water.

Detailed explanation-2: -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-3: -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-4: -(b) Seasonal drought: This drought can be expected in each year. These droughts are resulted from large seasonal air circulation changes. Agriculture is possible during the rainy season or with the use of irrigation in the dry season. Regions of seasonal drought have well defined rainy and dry seasons.

Detailed explanation-5: -A meteorological drought occurs due to lack of precipitation. A hydrological drought is related to low runoff, streamflow, and reservoir storage. An agricultural or ecological drought is causing plant stress from a combination of evaporation and low soil moisture.
