What is a drought?

A drought is a period of dry weather, especially a long one that is injurious to crops, or a prolonged period of abnormally low rainfall; a shortage of water resulting from this.


When and where do droughts typically occur?

They usually occur April through June.


The locations in our regions where they usually occur is in southeastern Wyoming, southeast Colorado, southern Nebraska, and northern Kansas.

What are causes droughts?

Lack of precipitation causes droughts. It causes the land to dry out. Precipitation is effected by global warming. Global warming is the gradual increase of temperatures of Earth's atmosphere. Global warming causes more evaporation to occur faster and changes in speeds of wind pushing precipitation away from the dryer areas making those areas dryer and dryer.


How Do Scientists measure droughts




2.0+

extremely wet



1.5 to 1.99

very wet



1.0 to 1.49

moderately wet



-.99 to .99

near normal



-1.0 to -1.49

moderately dry



-1.5 to -1.99

severely dry



-2 and less

extremely dry






Some factors that cause this type of severe weather in our region is lack of precipitation. Lack of precipitation is responsible because it is causing the land to dry out. Precipitation is affected by global warming. Global warming is the gradual increase of temperature of Earth’s atmosphere. Global warming causes more evaporation to occur faster and changes in speeds of wind push the precipitation away from the dryer areas making those areas dryer and dryer causing a drought.





Human Impacts

Some human impacts of droughts are that people could starve because of lack of food or they could be affected by dehydration for lack of water also for bathing, cooking, and dishes. Also people could be affected by inhaling dust.


Environmental Impacts

Some environmental impacts of droughts are that crops and plants die from lack of water and too much sun. There is a lack of drinking water for animals, as well as an increase in disease in them. There would be a lower water level and a loss in wetlands. There would be more wildfires and the quality of soil would be poor.
