In Africa, El Niño conditions are associated with increased rainfall in East Africa and decreased rainfall in southern Africa, West Africa, and parts of the Sahel.
What are some impacts of El Nino?
El Niño has affected food security and agricultural production, with cascading effects on livelihoods, health, water, sanitation, education and other sectors. This is due to flooding, disease outbreaks and malnutrition, disruption of health and education services, and overall increased mortality.
What causes the El Nino effect in Southern Africa?
El Nino is a change in weather patterns caused by the warming of the Pacific Ocean near the equator, off the coast of South America. … The current El Nino phenomenon is the strongest and longest in 35 years. The El Nino that hit Southern Africa has affected predominantly the food security of people in this region.
How does El Nino affect East Africa?
In East Africa, for the bimodal areas, El Niño events in the second half of the year usually lead to wetter than average conditions and are generally beneficial for agriculture. … For both bimodal and single season zones it can lead to flooding in riverine areas and increase the risk of livestock diseases.
What is El Nino and its effect?
El Niño is a phenomenon that occurs when unusually warm ocean water piles up along the equatorial west coast of South America. When this phenomenon develops, it affects weather patterns around the globe, including the winter weather along the west coast of North America.
What are the economic impacts of El Nino in Africa?
El Nino Impacts (2015/16 Season)
accompanied by high temperatures leading to: – Reduced crop yields – Cattle deaths – Low dam levels due to less inflows – Sectors affected include food security, livelihoods, agriculture, livestock, nutrition, health and water, sanitation and hygiene (WASH).
What are the impacts of El Nino and La Nina?
El Niño and La Niña affect not only ocean temperatures, but also how much it rains on land. Depending on which cycle occurs (and when), this can mean either droughts or flooding. Typically, El Niño and its warm waters are associated with drought, while La Niña is linked to increased flooding.
What are 3 effects of El Nino?
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.
What are the causes and effects of drought in southern Africa?
Drought in South Africa caused by El Niño, human action and climate change. The present drought in Cape Town has been caused by extremely poor rainfall in recent months, with the result that the water supplies are under enormous pressure.
What are the main causes of drought in southern Africa?
One of the main causes of drought in South Africa is the variability in rainfall (Mason and Tyson, 2000; Tyson and Preston-Whyte, 2000 and Vogel et al., 2000). The El Niño phenomenon accounts for approximately thirty percent of rainfall variability (Tyson and Preston-Whyte, 2000).
Is El Nino good or bad?
And for people across the Gulf States and the Eastern Seaboard, El Niño does one really good thing in the Atlantic Ocean in the summer and fall. It generates powerful high-altitude winds that cut the tops off of tropical storms before they can grow into hurricanes.
What is El Nino in simple terms?
El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO). … El Niño was recognized by fishers off the coast of Peru as the appearance of unusually warm water.
How does El Nino cause drought?
High-pressure systems reduce evaporation and moisture in the atmosphere. El Niño – as the surface temperature of the Pacific Ocean around the central South American coast increases, storm patterns are disrupted. This phenomenon is thought to create droughts in Indonesia and Australia.
