What was the temperature change of the surface waters during the 1997 El Nino event?
In 1997-98 and 2015-16, sea surface temperatures rose more than 2.5 degrees Celsius (4.5 degrees Fahrenheit) above the average.
What was the ENSO mode in the summer of 1997?
Paleoclimate records

Does El Nino increased water temperatures?
El Niño events are indicated by sea surface temperature increases of more than 0.9° Fahrenheit for at least five successive three-month seasons.
Was the 1998 El Nino predicted?
Several dynamical and statistical ENSO forecast models had success in predicting, one to three seasons in advance, unusually warm tropical Pacific SSTs for 1997. The first, and heretofore most successful, ENSO forecast model (Cane et al., 1986) failed to predict the 1997–98 event at all.
Which of the following event is an outcome of the 1997/98 El Niño event?
It led to a severe outbreak of Rift Valley fever after extreme rainfall in north-eastern Kenya and southern Somalia. It also led to record rainfalls in California during the water season of 1997–98 and one of Indonesia’s worst droughts on record.
What causes warm than normal sea surface temperature?
The primary cause of rising SST levels worldwide is climate warming due to excessive amounts of greenhouse gases being released into the atmosphere. Heat from the warming atmosphere raises the temperature of the sea surface.
Was there an El Niño in 1996?
The El Niño in 1997-1998 is a very strong El Niño. This is a strong La Niña, which occurs after some (but not all) El Niño years. 1995-1996 was a weaker La Niña year. It is unusual for El Niños to occur in such rapid succession, as has been the case during 1990-1994.
How does El Niño affect climate?
El Niño can affect our weather significantly. El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
What was the temperature change of the surface waters during this El Niño event?
During an El Niño water temperatures in the Pacific Ocean may rise on average 3 – 5 degrees above average. This happens as the water in seas around Indonesia, referred to as the Pacific Warm Pool are not forced westward due to weakened east to west trade winds.
Was there an El Nino in 1997?
The 1997–1998 El Niño was regarded as one of the most powerful El Niño–Southern Oscillation events in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe.
How does El Niño affect the water cycle?
It is well known that evaporation rates increase as temperature rises. During El Niño periods, reduced precipitation in these regions leads to lower terrestrial moisture content, so there is less water in the soil available to evaporate.
