EL Nino Vs. La Nina

EL Nino is a climate cycle in the pacific ocean with a global impact on weather patterns. EL Nino occurs every 3-7 years. During an EL Nino event, the relationship between winds and ocean currents in the pacific ocean changes, modifying weather conditions around the world. I do have a few question. What are some differences between EL Nino and LA Nina? What relationship is there between EL Nino and North Atlantic hurricanes? LA Nina and North Atlantic hurricanes?

EL Nino is a climate pattern that causes extreme weather conditions. EL Nino occurs when there is a large-scale warming of the surface of the pacific ocean, which can cause droughts, floods and even fishing and agriculture issues as its warm water move east.

EL Nino also “affects” wind shear, which is when air currents at a lower altitude blow in a different direction from winds higher in the atmosphere. On the other hand La Nina is the positive phase of the El Nino southern Oscillation and is associated with cooler- than average sea surface temperatures in the central and eastern tropical pacific ocean. El Nino is like La Niña brother, El Nino as the warm phrase and La Nina as the cold phrase. During an El Niño event, the relationship between winds and ocean currents in the Pacific Ocean changes, modifying weather conditions around the world.It is possible that WFP will be stretched operationally and financially during 2016 when the impacts of the El Niño event translate into increased food assistance needs across most of our areas of operation. Oscillations occur naturally in oceans all across the world; some have a limited impact on the regional weather and wider climate, and some have a much greater impact (4). El Niño and La Niña are examples of oscillations that have a greater impact on our climate with effects that are perhaps surprisingly felt all over the globe (5).
