El -nino messaging volatile climate division weather agencies

(Bloomberg)-For the global markets, the beginning and intensity of weather-colored El Nino and La Nina, and meteorologists need to get the right or risk sparkling confusion and backlash to messaging.

Australia’s forecast, which faced criticism after an unusual L. Nino last year, is taking at least approach, while the World Meteorological Organization and the Philippines are fielding requests for more detailed and constant information. . Unlike styles underlined the challenge for agencies seeking to balance demands for certainty against weather volatility.

El Nino-south reading a accurate read on the position of oscillation, it is necessary to plan its crop regime for governments, energy markets and farmers, especially global warming increases extreme weather. Warm and cold stages can cause dry droughts or increase rain from Asia-Pacific to America, and the global economy can cost trillions.

“This is important information,” said Triston Mayor, a meteorologist at New Zealand’s National Institute of Water and Atmospheric Research. “It gives you a little insight on how the weather will develop.”

For the first time, South American fishermen focused on unusually hot water duration in the Pacific Ocean, which they named El Nino de Navadad, and modern researchers realized its importance for the global season in the 1960s. Was. La Nina was nominated after nearly two decades and today, climate variations are monitored by an array of aunt in the Pacific region.

According to a spokesperson, Australia’s Weather Bureau stopped releasing its fortnightly updates in December as they “as a prophet of seasonal circumstances made an excess and” possibility and severity of weather events “on ENSO as a prophet. It is said that its long -term forecasts at rain and temperature are a better guide.

“El Niinos and La Niyanas reduce the possibility of wet or dried, or hot or cooler or cooler conditions in different parts of the world, but they do not dismiss the possibility of contrast,” Andrew King said, an associate Professor Andrew King said, Climate Science at Melbourne University.

That subtlety can often be lost in communication, as Australia Bureau found after the announcement of Al Nino in late 2023. Despite the call being correct, the agency faced intensive criticism after an etipical incident: wet rather than dry.

Rice Turton, a crop farmer in Western Australia and president of the industry group Gringravers Limited, said, “It has a huge impact when the forecasts are going very wrong.” The season, such as what to plant, or how much to plant. ,

People want certainty from a discipline that cannot distribute it, according to the John Gots operator of the Operating Prophecy Branch of the US Climate Prophecy Center. The forecasts are based on possibilities and sometimes unpredictable or at least results, which can cause complaints.

“The nuances in our forecasts mean something, even though stakes do not like to see it,” Gotschelk said, “NSO is still the most predicted seasonal and inter-yearly prediction that we have.”

The ENSO is monitored using sequences that measure deviations in the temperature of the Pacific Ocean from the average in the earlier decades, and with the warm of the world, El Niinos is underestimated by reducing and lower Niyanas. Some global warming are using methods of removing background noise, but more research on their effectiveness is required.

For example, the American agency, informally tracks a relative Oceanic Nino Index that reduces tropics-wide C temperature discrepancy. Relative remedies are at least 0.5C (0.9F) – compared to the traditional index compared to the previous year – is a very threshold that makes or breaks or breaks or breaks the events.

Even without the challenge of a warming world, the global ENSO forecast can still cause uncertainty, this year’s Yes-No La Niña is an example of that Conundrum. Earlier this year, the Philippines and the United States stated that La Neena developed, while Japan and Australia still see the situation as neutral. ENSO is stems of unity from each nation using various standards to measure thresholds.

“It is like a Philharmonic concert without a conductor. Each device, whether it is Australian one or American one, or French one, they play their best score perfectly, but it never stops cacophone, ”a meteorologist and chief of climatology division, Alexandre Peltere Said. Meto-France in New Caledonia.

WMO, a United Nations Agency, who already releases the ENSO Outlook by drawing on the forecasts of several dozen weather centers worldwide, creating a new “one-stop repository” to provide more detailed and frequent information. The hub has been in response to the growing demand from member states after “rapid development of ENSO events” in recent years, the head of the Climate prediction services at the Wilfran Moufouma Okia, the agency.

In the Philippines, the weather agency of the country is demanding more detailed information to suit specific areas and industries, including advice on what to do before, during and after the El Nino or La Nina. The nation is at the forefront of typhoon arising in the Western Pacific.

For Australia, its bureau will still announce if there is a change in the ENSO situation, although a least approach can still cause issues. Raja University of Melbourne said that it leaves a vacuum to be filled with less reliable sources that can make some weather agency wrong.

“The bureau ends with a worse result, potentially,” he said.
