How is La Nina different from El Nino?
El Nino refers to the above-average sea surface temperatures periodically developing in the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Nina refers to the periodic cooling of sea surface temperatures in the east-central equatorial Pacific.
Which is worse, La Nina or El Nino?
El Nino is often (but not always) followed by La Nina the following year, especially if the El Nino is strong. During La Nina Weather conditions, the easterly trade winds will become even stronger than usual near the equator. Stronger winds push surface waters into the western Pacific.
What is El Nino and La Nina and what are the characteristics of each?
El Nino is characterized by a positive ONI greater than or equal to +0.5 °C. La Nina is characterized by a negative ONI less than or equal to -0.5°C. When the ONI is between +0.5 and -0.5, it is said to be conditional ENSO-neutral.
Is 2020 an El Nino or La Nina?
That 2020-2021 La Nina The event is complete, according to both oceanic and atmospheric indicators.

Is La Nina good or bad?
In general, la Niñas produce warmer and drier fall, giving some of the Midwest crops planted late during the spring floods enough time to mature. This helps the food price. Unfortunately the La Nina there will also be dry conditions in Texas that could really use some rain.

Why does La Nina happen?
La Nina is caused by an accumulation of cooler than normal water in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn. Unusually strong eastward trade winds and ocean currents bring this cold water to the surface, a process known as upwelling.
