When was the last El Nino in Kenya?
When was the last El Nino in Kenya?
Kenya experienced extraordinarily heavy rainfall between May 1997 and February 1998 due to the El-Nino weather phenomenon. This period of about 10 months heavy rainfall caused widespread landslides and floods which were experienced in various parts of the country.
Where did El Nino hit?
Impact. The El Niño event affected millions of people around the world, including in Africa, Central America, Southeast Asia, and the Pacific Islands. These effects included below or above-average rainfall, flooding, increased food insecurity, higher malnutrition rates and devastated livelihoods.
When was last El Nino?
Recent Central Pacific El Niños happened in 1986–87, 1991–92, 1994–95, 2002–03, 2004–05 and 2009–10. Furthermore, there were “Modoki” events in 1957–59, 1963–64, 1965–66, 1968–70, 1977–78 and 1979–80. Some sources say that the El Niños of 2006-07 and 2014-16 were also Central Pacific El Niños.
Where does El Nino occur in Africa?
El Niño is commonly linked to droughts in southern Africa and extreme rainfall in eastern Africa.
What El Nino Do?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
Why does El Niño affect Africa?
Higher sea surface temperatures warm the atmosphere during the El Niño phase, resulting in greater convection and rainfall over Eastern Africa. By contrast, a continental high-pressure system dominates Southern Africa and suppresses regional atmospheric convection and rainfall (Mulenga et al., 2003).
Which five African countries are commonly affected by the El Niño weather phenomenon?
El Niño has already triggered drought in Ethiopia, northern Somalia, Sudan, Eritrea, Djibouti and eastern Chad. As of 4 July, approximately 28 million people in the Horn of Africa region were in Crisis or Emergency food security outcomes (IPC Phases 3 and 4) and in need of immediate humanitarian assistance.
Why is it called El Niño?
Fishermen off the west coast of South America were the first to notice appearances of unusually warm water that occurred at year’s end. The phenomenon became known as El Niño because of its tendency to occur around Christmas time. El Niño is Spanish for “the boy child” and is named after the baby Jesus.
What is the El Niño status now?
The El Niño of 2019 is officially done. Neutral conditions have returned to the tropical Pacific, and of the three possible outcomes—El Niño, La Niña, or neutral—forecasters favor neutral to persist through Northern Hemisphere winter. More ENSO status information.
What are El Niño and La Niña?
El Niño and La Niña are the warm and cool phases of a recurring climate pattern across the tropical Pacific—the El Niño-Southern Oscillation, or “ENSO” for short. The pattern can shift back and forth irregularly every two to seven years, and each phase triggers predictable disruptions of temperature, precipitation, and winds.
How does El Niño affect the weather in the summer?
In the summer, El Niño’s primary influence on U.S. climate is on the hurricane season in both the eastern Pacific and the Atlantic. El Niño has its strongest influence on global climate during the Northern Hemisphere winter, but summer impacts do occur, especially in the tropics.
What are the odds of a neutral El Niño?
The El Niño of 2019 is over, and neutral conditions have returned to the tropical Pacific. Of the three possible outcomes—El Niño, La Niña, or neutral—forecasters give neutral the highest odds (75% chance) of lasting through winter.
Did an El Nino event occur in 2015 2016?
The 2015/2016 El Niño event was one of the strongest of the last 145 years, resulting in anomalously high wave energy across the U.S. West Coast, and record coastal erosion for many California beaches.
When was the last time El Nino hit?
Recent Central Pacific El Niños happened in 1986–87, 1991–92, 1994–95, 2002–03, 2004–05 and 2009–10. Furthermore, there were “Modoki” events in 1957–59, 1963–64, 1965–66, 1968–70, 1977–78 and 1979–80.
How is Africa affected by El Nino?
El Niño is commonly linked to droughts in southern Africa and extreme rainfall in eastern Africa. Drought and flooding in sub-Saharan Africa are often considered most closely in relation to risks to agriculture. But increasing urbanisation is changing the nature of climate risk in the region.
Was there an El Niño in 2017?
While 2017 started out unusually warm – especially for a year without major El Niño event – it has cooled off notably in recent months. The figure below shows monthly temperature estimates from 2012 through to today from each of the groups reporting global surface temperatures.
Why does El Niño cause disease?
In tropical regions like Brazil and Southeast Asia, drought and above-normal temperatures caused by El Niño can alter the habitat and life cycles of mosquitoes that carry dengue fever, amplifying outbreaks (check out this neat video for more information).
Is El Nino wet or dry?
Weather typically differs markedly from north to south during an El Niño event (wet in south, dry in north) but also usually varies greatly within one region from event to event.
What are the impact of El Niño in people?
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 are the impact of El Niño on the economy?
These extreme weather conditions can constrain the supply of rain-driven agricultural commodities, lead to higher food prices and inflation, and may trigger social unrest in commodity-dependent countries that rely primarily on imported food.
Is 2018 an El Nino year?
The Great Puny El Niño of 2018–19 continued through March, and forecasters predict it will likely remain through the summer and possibly continue into the fall. The tropical Pacific Ocean shows El Niño’s fingerprint clearly, with warmer-than-average sea surface temperatures stretching across the equator.
Was 2017 the hottest year?
After three consecutive years of record-high temperatures for the globe, Earth was a slightly cooler planet in 2017. Earth’s globally averaged temperature for 2017 made it the third warmest year in NOAA’s 138-year climate record, behind 2016 (warmest) and 2015 (second warmest).
