How are droughts measured for kids.
Drought is something most places on earth will experience at some point: Anywhere that has water can have drought.
What is drought monitoring
But what makes a dry period a drought? It’s about the balance of moisture in a given place, driven by the supply and demand of water.
What is drought?
Drought is a temporary state of dryness that represents an aberration from the historical norm.
Drought can result from low supply of precipitation (less rain and snow) as well as high demand for moisture, resulting from high evaporation due to high temperatures, or more sunlight.
What causes drought?
Every place has unique patterns of supply and demand of water that keep local moisture levels within a range that plants, animals, and even people are used to.
Low supply—resulting from less precipitation—is usually the main driver of drought.
Because all local plant and animal life is adapted to a certain amount of precipitation, when that amount drops, the demand for moisture is greater than the supply. High demand can also play an important role in driving drought.
