How do droughts develop and last for months or years?
Drought develops when precipitation stays below normal for a long period, often combined with high temperatures and strong evaporation. Soil, rivers, and reservoirs then slowly run out of water.

Why do some regions become drought-prone for years at a time?
Persistent shifts in atmospheric circulation can keep storm systems away from a region. Warm ocean conditions and land-atmosphere feedbacks can then lock in dry weather.
