Question

when does a drought occur​

Answer 1

Answer:

Droughts happen when there is not enough rain for a long period of time. It's not like a dry spell - there is so little precipitation (rain, snow, sleet or any kind of moisture) that a whole region starts to dry out.

Sometimes a drought takes decades to develop fully and they are very difficult to predict.

Environmental things like climate change, ocean temperatures, changes in the jet stream, and changes in the local landscape all make a difference when it comes to droughts.
