Was there an El Nino in 2015?
Was there an El Nino in 2015?
The 2015/16 El Niño broke warming records in the central Pacific, represented by the NINO3. 4 and NINO4 indices. At its peak in November 2015, the NINO3. 4 SST anomaly reached 3.0°C, breaking the previous record of 2.8°C set in January 1983.
Was December 2015 an El Nino year?
The warm up for the 2015 El Niño event actually began in 2014. By December 2015*, however, disruptions in temperature, rainfall, and surface air pressure across the tropical Pacific were on par with two of the strongest El Niños in the historical record: 1982 and 1997.

Was there an El Niño in 2015 2016?
The 2015-2016 El Niño event brought weather conditions that triggered regional disease outbreaks throughout the world, according to a new NASA study that is the first to comprehensively assess the public health impacts of the major climate event on a global scale.
Is El Niño bad?
If El Niño has a strong presence, or makes Pacific waters warmer than usual, it increases the amount of “wind shear” across the the Atlantic basin. Wind shear is bad for hurricanes, and tropical storm production. It disrupts necessary conditions for tropical storms to form.
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).
How many people died because of El Niño?
The event was blamed for between 1,300 and 2,000 deaths and more than $13 billion in damage to property and livelihoods.
How El Niño affect human activities?
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.
Will there be another El Niño in 2017?
The latest forecasts for 2017 at the time of going to press are indicating the possibility of another El Niño developing later this year. El Niño is the warm phase of the El Niño Southern Oscillation (ENSO). The cool phase is known as La Niña.
Was El Niño 2015/16 the biggest event in history?
The 2015/16 El Niño turned out to be in the same class as the biggest such events recorded in the 20th century. Its evolution was well predicted by ECMWF forecasts as well as by EUROSIP multi-model forecasts.
What is El Niño and why does it matter?
Two years ago, forecasting systems were predicting the development of a potentially major El Niño – a warming of the equatorial Pacific Ocean which has impacts on weather patterns around the world. The 2015/16 El Niño turned out to be in the same class as the biggest such events recorded in the 20th century.
What was the strongest El Niño in 1997?
Anything above 0.5 is considered El Niño conditions – and anything above 1.5 is a strong El Niño. The strongest El Niño was the 2.3 event in 1997-98. The current figure for this year’s El Niño is 2.0 and has been rising for months – and many are forecasting the strongest El Niño since records began in the 1950s. What happened in 1997?
