Which drought category is defined by prolonged failure of rainfall leading to reduced atmospheric moisture over a region?

• A. Meteorological drought
• B. Agricultural drought
• C. Hydrological drought
• D. Economic drought

Answer: (A)

Understanding how droughts are classified by what part of the environment they affect is key. When rainfall fails for an extended period, the region’s atmosphere becomes drier because less moisture is entering the air from precipitation. This reduction in precipitation and atmospheric moisture defines meteorological drought. It is the form of drought described by a sustained deficit in rainfall and the resulting lower moisture content in the region’s atmosphere. Other types focus on different consequences: agricultural drought looks at soil moisture and crop health, hydrological drought deals with water resources like rivers and reservoirs, and economic drought concerns the financial impacts that arise from drought conditions. Since the scenario centers on a prolonged rainfall failure and decreased atmospheric moisture, meteorological drought is the best fit.
