There has been intense debate about the causes of the 1997-1998 El Nino. One side sees the obvious intense westerly wind events as the main cause for the exceptional heating in summer 1997, the other emphasizes slower oceanic processes. We present a quantitative analysis of all factors contribu...
The surface can stay warm for a while, but once the heat from the subsurface is gone and the trade winds return, the El Niño event collapses. At the end of past El Niño events, the sea surface anomaly dropped very fast and we saw conditions typically switch to La Niña – El N...
Collectively, El Niño and La Niña are parts of an oscillation in the ocean-atmosphere system called the El Niño-Southern Oscillation, or ENSO cycle, which also has a neutral phase. What causes an El Niño? Scientists do not yet understand in detail what triggers an El Niño cycle...

What is El Niño? This year marksthe return of El Niño, a natural climate phenomenon that develops every two to seven years when the Pacific Ocean experiences "warmer-than-average" surface temperatures.NOAAexplains that the event weakens trade winds as warm water is pushed toward the west ...
change in the pressure gradient causes the trade winds to weaken or, in some cases, to reverse. This then causes the warm water in the western Pacific to flow eastward, increasing sea-surface temperatures in the central and eastern Pacific. The eastward shift signals the beginning of an El ...
El Niño and La Niña: the causes and effects on climate, people and energy Sometimes, in the Pacific Ocean, abnormal turbulence or disturbances can alter the regular pattern of winds and thus ocean currents: the result is an increase in water surface temperatures. When this warming is more...
Arming yourself with as much information as possible before an event occurs is essential. Make sure you download theBOM appas well as state and territory government apps to alert you to weather-related dangers. In addition, it’s always a good time to check yourhome and contents insurance* ...

The meaning of El Nino and La Nina The status of whether the world is being impacted by an El Nino or a La Nina is determined by water temperatures in the central and eastern Pacific. (NOAA) Water temperatures in the Pacific play a prominent role in climate patterns around the world and...
