What causes a drought to happen?

The Short Answer: A drought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by evaporating moisture from the soil. A drought is a prolonged period with less-than-average amounts of rain or snow in a particular region.

Which drought is related to rainfall?

Hydrological drought is associated with the effects of periods of precipitation (including snowfall) shortfalls on surface or subsurface water supply (i.e., streamflow, reservoir and lake levels, groundwater).

How does lack of rainfall causes drought?

When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought (Moreland, 1993).

• 3) Soil moisture levels also contribute to drought.
• 4) Drought can also be a supply and demand of water issue.
