2023年9月22日 · El Niño is a climate phenomenon characterised by the periodic warming of sea surface temperatures across the Pacific Ocean. During an El Niño event, the trade winds, which usually blow from east to west along the equator, weaken or reverse displacing warm waters eastwards that are typically confined to the western Pacific Ocean. This can ...

2016年3月29日 · The GBR joins a lengthening list of reefs bleached because of the El Niño that started in late 2014. It is now the longest bleaching event ever, and this El Niño, which helped make 2015 the planet's hottest year on record, "isn't even close to being over," says Mark Eakin, a coral reef ecologist at the U.S. National Oceanic and Atmospheric ...

El Niño means 'the little boy' in Spanish, first named in the 1600's by Spanish fishermen who noticed unusually warm waters around the end of December. #How El Niño impacts the Great Barrier Reef. Higher than average ocean temperatures can cause heat stress for corals, which can lead to mass coral bleaching events. ...

2020年5月18日 · Widespread coral bleaching across the Great Barrier Reef (GBR) in 2016 is often reportedly caused by El Niño and/or global warming. However, the GBR is not in a region where it is straightforward to anticipate sea surface temperature (SST) warming during El Niño, and the role of climate change is unclear. This study uses a diverse range of ...

The 2016 bleaching event in the GBR is often reportedly associated with global warming and/or El Niño. However, the GBR is not in a region where it is straightforward to anticipate SST warming given an El Niño event (Lough, 1994; Zhang et al., 2017). Regardless of El Niño “flavor” (i.e., whether the maximum

2017年10月9日 · Along the Great Barrier Reef (GBR) (Figure 1), El Niño typically brings drier conditions (Risbey et al., 2009) due to a weakened monsoon, higher sea level atmospheric pressure, more frequent winds from the east and southeast, and cool SSTs in spring and early summer which may become warmer than average by late summer (Lough, 1994).

2016年5月6日 · The warmth associated with El Niño (the warm phase of a natural climate pattern that swings back and forth in the tropical Pacific) was a major contributor to this record-breaking bleaching event on the Great Barrier Reef, but long-term warming trend in the oceans worldwide due to human-caused climate change is the underlying cause.

2024年7月2日 · Extreme El Niño events, for example, were the leading drivers of the mass bleaching events in the GBR that occurred in 1983, 1998 and 2016 (Hughes et al., 2017). ENSO drives ocean temperature variability in this region indirectly through the local meteorology established by ocean-atmosphere feedbacks (Mcgowan & Theobald, 2017 ), as shown in ...

2022年12月9日 · The El Niño Southern Oscillation (ENSO) is the strongest source of interannual global climate variability, and extreme ENSO events are projected to increase in frequency under climate change. ... (GBR). We investigated larval connectivity during ENSO events from 2010 to 2017 throughout the GBR, based on biophysical modelling of a widespread ...

2022年12月9日 · Poleward larval connectivity predominated throughout the central and southern GBR during the 2014 El Niño alert and strong 2015 El Niño events (79% and 71% of connections, respectively) (Fig. 4a,b).
