A new study has been issued in the journal Nature Geoscience in which Australian scientists have detected various kinds of El Nino events. Researchers have created an approach to develop a first 400-year cyclic record of El Nino occurrences. The mentioned above record was tagged by the majority of scientists working in the field as too complex to be excerpted.
El Nino events generate extreme weather all over the planet with specifically severe impacts for precipitation and climate limits in South East Asia, Australia and both North and South America. The research showed an increase in El Nino forms in Central Pacific motion starting with the last part of the 20th Century, also revealed that the power of the Eastern Pacific event would also change.
As part of Dr. Mandy Freund, the lead author of the study and Ph. D. research at the University of Melbourne and the Centre of Excellence for Climate Extremes, the result of the study was extracted from coral cores covering the Pacific Ocean. Dr. Ben Henley, the co-author from the Centre of Excellence for Climate Extremes, said that before this research, the frequency of the El Nino events was unknown all over this time.
Researchers recreated the El Nino record and revealed the changes influencing the phenomenon
What it actually took to create the record was to comprehend that coral details held sufficient data to discover seasonal modifications in the tropical Pacific Ocean. Even so, by utilizing coral records to rebuild El Nino background at a seasonal timeframe have never been achieved before so many scientists thought it was not possible.
Even if some considered the approach a bit unorthodox, Dr. Freund shared her idea with a team of specialists which consisted of Dr. Ben Henley, Professor David Karoly, Associate Professor Helen Mcgregor, Associate Professor Nerille Abram, and Dr. Dietmar Dommenget and they pursued the concept. To see the similarities and opposites between recent corals and the useful record, the team improved the method to recreate the mark of El Nino in space and time utilizing new machine learning methods.
Dr. Freund discovered a high level of similarities between the recorded occurrences and the coral hearts. The doctor and her team identified an unexpected rise in the El Nino events taking shape in the Central Pacific during the last three decades, in comparison to all three decades in the previous 400 years. The research took three years to complete.
