During an El Niño event, ocean temperatures in the central and eastern Pacific Ocean rise, leading to significant weather changes globally, such as increased rainfall in the southern U.S. and drought in Australia. Conversely, La Niña, characterized by cooler ocean temperatures in the same region, typically results in opposite weather patterns, including wetter conditions in Australia and dryer conditions in the southern U.S. Both phenomena can disrupt normal weather patterns, impacting agriculture, fisheries, and ecosystems. Their effects can vary in intensity and duration, influencing climate variability around the world.

During El Niño, the western coast of South America typically experiences warmer and wetter weather conditions than usual. This can lead to heavy rainfall, flooding, and increased risk of landslides in the region.
During an El Niño year, the pressure in the central and eastern Pacific Ocean decreases, leading to weaker trade winds and warmer sea surface temperatures. This shift in atmospheric pressure results in increased precipitation in the eastern Pacific and drier conditions in the western Pacific. Conversely, during a La Niña year, the pressure patterns reverse, with increased pressure in the eastern Pacific, stronger trade winds, and cooler sea surface temperatures, often causing wetter conditions in the western Pacific. These fluctuations significantly impact global weather patterns.
During El Niño, wind patterns can be disrupted, leading to less reliable wind conditions for windmills. This can affect the efficiency and output of electricity generated by wind turbines. Additionally, extreme weather events associated with El Niño, such as storms or hurricanes, can also pose risks to windmill infrastructure.
During an El Nino event, there tends to be fewer hurricanes in the Atlantic Ocean. This is because El Nino conditions typically create stronger wind shear over the Atlantic, which can inhibit hurricane formation and intensification.

Expected Loss (EL)EL for a single asset is calculated by using the following formula:EL = AE * LGD * EDFTo calculate EL for a portfolio we must add the expected losses of the individual assets; formula below:ELP = ∑ELi
