During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.

El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO). El Niño events occur irregularly at two- to seven-year intervals.

An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.

Features of EL Nino. (i) The presence of the EL-Nino leads to an increase in sea-surface temperatures. (ii) It weakens the trade winds in the regions and causes heavy rainfall, floods or droughts in different regions of the world.

On the other hand, in the United States, El Niño typically brings wet weather to California (benefiting lime, almond, and avocado crops, among others), warmer winters in the Northeast, increased rainfall in the South, diminished tornado activity in the Midwest, and a decrease in the number of hurricanes that hit the …

There are several means used for El Niño detection; satellites, moored ATLAS and PROTEUS buoys, drifting buoys, sea level analysis, and XBT’s. Since El Niño influences global weather patterns and affects human lives and ecosystems, prediction of an El Niño event is becoming increasingly important.

Which statement describes the negative effects of El Niño? Rain, flash floods, and mudslides occur in places where there is usually little rain, while usually wet areas suffer from drought. Upwelling is a process in which warm, nutrient-rich water from the deep ocean rises to the surface.

BARCELONA – The complex El Nino weather pattern that can bring disastrous heavy rainfall and long droughts to countries around the Pacific — from Peru to Indonesia and Australia — will probably emerge again in 2020, researchers have predicted. …

Can we prevent El Niño and La Niña from occurring? No, El Niño and La Niña are naturally occurring climate patterns and humans have no direct ability to influence their onset, intensity or duration.

El Niño is associated with death and disease, most of which result from weather-related disasters such as floods and droughts. In 1997 Central Ecuador and Peru suffered rainfall more than 10 times normal, which caused flooding, extensive erosion and mudslides with loss of lives, destruction of homes and food supplies.

El Niño and La Niña are abnormal episodes of warming or cooling of surface ocean waters in the eastern tropical Pacific. When the waters of the eastern Pacific are abnormally warm (an El Niño event) sea level pressure drops in the eastern Pacific and rises in the west.

The 2020-2021 La Niña event has concluded, according to both oceanic and atmospheric indicators. In 2021, the sea surface temperature anomalies in the eastern-central Pacific weakened, leading to the currently prevailing weak cool anomalies that are not cold enough to meet the La Niña threshold.

The impacts of La Niña on our weather and climate have been highly variable throughout history. La Niña delivers drier, warmer, and sunnier weather along the southern tier of the United States, from California to Florida. This weather increases the risk of wildfires in Florida and dryness in the North American plains.
