Exploring causal pathways among soil moisture, climate and ocean–atmosphere teleconnection patterns over the drought-prone Greater Horn of Africa

Drought over the Greater Horn of Africa (GHOA) is a recurring phenomenon primarily associated with precipitation deficit which leads to decreased soil moisture. Understanding the interactions among atmosphere, ocean, climate, and soil is therefore necessary for water resource management, drought monitoring, and disaster prevention. Assessing those interactions so far primarily focused on dynamic climate models and statistic models. However, the …
