Weather in Germany 2023: hot summer threatens due to climate phenomenon
New Year’s Eve was the warmest since weather records began. But now it could be really hot. Weather phenomenon El Niño announces a hot summer 2023.
Geneva/Dortmund – Hot, hotter, 2023: Weather experts around the world are warning that 2023 will see unprecedented heat. Temperatures of up to 50 degrees are warned in regions such as Southeast Asia, for example. reason is that weather-The El Niño phenomenon. “Exceptionally warm deep water in the tropical western Pacific predicts the next El Niño event in 2023,” said Kevin Trenberth, a climate researcher at the University of Auckland in Australia.
El Niño approaching: According to experts, the weather phenomenon could result in a hot summer in 2023
“All models show a large El Niño phase for late spring and summer 2023. It will probably be a very strong El Niño phase with record temperatures worldwide,” confirms the German climatologist Dr. Karsten Brandt from Donnerwetter.de opposite of picture. Also the The 100 year calendar says extreme heat in 2023 ahead.
Brandt urgently warns of extreme drought and heat – especially in South Africa. For Brazil, Venezuela and the rest of South America, the heat records could mean more fires in the rainforests, reports kreiszeitung.de. And in Southeast Asia, Brandt warn of extreme temperatures between 45 and 50 degrees. But also the northeast coast of the USA: “Too warm,” says Brandt. Also the Summer 2022 was already heated.
What are La Niña and El Niño?
The correct name is “El Niño Southern Oscillation” or “Enso” for short. It describes a coupled circulation system of ocean and atmosphere in the tropical Pacific. During the warm phase El Nino brings the flow of sea heat at higher latitudes, which is partly released into the atmosphere via evaporation.
La Nina is considered a cold phase in which the current carries the warming via solar radiation into deep waters of the western Pacific, where it is stored. Because fishermen in Peru noticed the warming at the end of the year, they called the phenomenon El Niño (the Christ Child). Between the two extremes one speaks of a neutral phase. (DPO)
Graduate meteorologist Dominik Jung von blows the same horn weather.net. “We currently have La Nina and still got the warmest year since 1881. It doesn’t look too good for this year either. Maybe 2023 will top the year 2022,” she quotes picture the weather expert.
El Niño ensures hot summer 2023: 2022 was one of the warmest years since measurements began in 1850.
Then already 2022 was one of the warmest years since measurements began in 1850. This is also worrying because it coincides with the cooling effect of the La Niña weather phenomenon. Now there are increasing signs that the three-year La Niña phase, which is unusually long, is coming to an end. The counterpart El Niño could soon follow, which can also drive up the temperatures.
In November, the World Weather Organization (WMO) in Geneva estimated the probability at 25 percent that an El Niño phase would begin in the summer. The probability that the previous record of the hottest year to 2026 will be surpassed is 93 percent. The record year was 2016, with a global average temperature of 1.3 degrees above the 1850-1900 level.
Hot summer 2023: Many regions are particularly at risk
According to the WMO, strong and moderate El Niño events contribute to warming and an increase in the average global surface temperature. “Although the strong effects of El Niño are felt in the equatorial Pacific, they can affect weather around the world by affecting high and low pressure systems, winds and precipitation,” explain Columbia University climate researchers. “As warmer ocean water releases excess energy (heat) into the atmosphere, global temperatures are rising.”
The El Niño weather phenomenon is approaching: in 2022, the average temperature was already 1.15 degrees too warm
WMO chief Petteri Taalas warned in August 2022: “To have La Niña events for three consecutive years is very extraordinary. The cooling effect has temporarily slowed the rise in global temperatures, but that will not halt or reverse the warming trend.”
According to a preliminary forecast against La Niña, 2022 was one of the warmest years since the beginning of industrialization. The WMO estimated the global average temperature in November to be about 1.15 degrees above the average for the years 1850 to 1900. In addition, the years 2015 to 2022 were the eight warmest years.
