Describe the causes of drought.

Drought is a prolonged period of abnormally low rainfall, leading to a significant water shortage. It is a complex phenomenon that arises from a combination of natural and human-induced factors. Droughts can have severe impacts on ecosystems, agriculture, water resources, and communities, often leading to environmental and occupational hazards. Understanding the causes of drought involves examining various climatic, geographical, and human factors that contribute to its development.

### 1. Natural Climatic Factors

One of the primary causes of drought is natural climatic variation, driven by both short-term and long-term changes in atmospheric conditions. These include:

#### a) El Niño and La Niña Phenomena
El Niño and La Niña are large-scale climate phenomena linked to the periodic warming and cooling of sea surface temperatures in the central and eastern Pacific Ocean. El Niño, in particular, is often associated with reduced rainfall in regions such as Southeast Asia, Australia, and parts of Africa, leading to drought. La Niña, the opposite phase, can cause drought conditions in areas like the southwestern United States, due to its influence on atmospheric circulation patterns. These phenomena disrupt typical rainfall patterns, contributing to drought in many parts of the world.

#### b) Climate Variability
Natural climate variability, driven by atmospheric circulation patterns such as the jet stream, can cause irregularities in ____ _________ ___ ________ __________ ___ ______.
