A long period of low rainfall is generally known as a long-term drought, defined by a prolonged precipitation deficit.
According to the reference material, the duration distinguishes between short-term and long-term droughts. A long-term drought, as opposed to a short-term drought, lasts significantly longer.
Long-Term Drought Explained
| Aspect | Description |
|---|---|
| Definition | A sustained period of significantly below-average precipitation. |
| Duration | Typically more than six months of precipitation deficit. |
| Impacts | Reduced water availability, agricultural losses, increased wildfire risk, and potential ecosystem damage. |
| Reference | "Defining Short- and Long-Term Drought" states that precipitation deficits lasting more than six months are typically considered long-term drought. |
In simpler terms, if an area experiences much less rain than usual for over half a year, it's classified as a long-term drought.
