[1] This current is heavily influenced by the monsoons and is the only major upwelling system that occurs on a western boundary of an ocean. Ocean surface temperatures are an important data source for monitoring global warming; therefore it is important to record the temperatures found during the northern (summer) swing of the Somali Current. The Somali Current is of interest because it creates an upwelling of cold water that is the only other region of such low surface temperatures within 10 degrees of the equator outside of Peru, and perhaps even colder. According to a recent study, there has been a strong link between global warming and increased dryness in the Horn of Africa over the past 2000 years.
