El Nino Declared by Australian Bureau of Meteorology, Impacting Global Weather Patterns: First in 7 Years
Sydney – The Australian Bureau of Meteorology (BOM) officially declared the presence of an El Nino weather event today, marking a significant development in global weather patterns. This declaration comes two months after the World Meteorological Organization first announced the emergence of El Nino conditions in the tropical Pacific, a phenomenon not seen in seven years.
Karl Braganza, Manager of Climate Monitoring at BOM, addressed reporters during a media conference on Tuesday afternoon, shedding light on the bureau’s efforts in monitoring and confirming the El Nino event. He explained that BOM had initially issued an El Nino Watch in March, later elevating it to an alert in June. The subsequent wait was for the crucial moment when the atmosphere synchronized with the ocean, confirming the El Nino pattern.
“In the last two weeks, we have observed the atmosphere over the tropical Pacific responding to this pattern, ultimately locking in the ocean-atmosphere coupling,” Braganza stated.
Additionally, Braganza highlighted the concurrent occurrence of a positive Indian Ocean Dipole (IOD) event in Australia. When these two phenomena coincide, they tend to exacerbate rainfall deficiencies in the southeastern regions of the continent during the spring season, he explained.
The latest Climate Driver Update issued by BOM further emphasizes the significance of these dual weather events and their implications for Australia. The bureau’s long-range forecasts now indicate a likelihood of warmer and drier conditions prevailing across much of the country over the next three months.
Moreover, the BOM underscored that the combination of a positive IOD and El Nino typically results in a more potent and widespread drying effect across Australia.
“El Nino is known to impact global temperatures, and we can expect this influence to persist until the middle of next year. Unfortunately, we’re likely to witness a continuation of the global warming trend until the middle of 2024,” Braganza cautioned.
This declaration by the Australian Bureau of Meteorology has broader implications for global weather patterns and underscores the need for careful monitoring and preparedness in the face of changing climatic conditions. As the world grapples with the consequences of El Nino and its potential impact on temperatures and rainfall, scientists and meteorologists are closely watching the developments.
The declaration of El Nino by the BOM aligns with the World Meteorological Organization’s earlier assessment, further strengthening the case for proactive measures to mitigate the potential effects of this weather phenomenon.
In conclusion, the Australian Bureau of Meteorology’s formal declaration of El Nino, coupled with the simultaneous occurrence of a positive IOD event, presents significant challenges for Australia’s weather outlook in the coming months. These events are not isolated occurrences but are part of the larger global climate puzzle that will require ongoing attention and monitoring.
