"49.9 degrees Celsius in some areas". Why is there such hot weather in Australia?

Although Australia has a tropical and subtropical climate, this high temperature is really outrageous. In fact, last year, nearly 90 regions in Australia set the highest temperature, which also triggered forest fires. Such a serious high temperature anomaly is mainly due to two aspects, one is global warming, and the other is climate anomaly caused by El Ni? o phenomenon.

0 1. Australia's climate is unusually high, and mountain fires are constantly killing koalas.

If Australia was the key word last month, it must be? Fire? . Mountain fires in Australia have burned 6.3 million hectares and almost half of Britain. From last year to this year, from 10 to the 1920s, nearly 10,000 koalas were burned to death, and about 500 million birds and animals were buried in the sea of fire. The whole of Australia didn't see the blue sky, and the sky was smoked into dark yellow by fireworks. The reason why this mountain fire is so fierce is because of the high temperature. Long-term high temperature, no precipitation, and continuous strong winds lead to a single spark, which eventually leads to a prairie fire.

02. The abnormal weather caused by El Nino made Australia miserable.

The first cause of global warming is well known, so I won't go into details here, mainly talking about El Nino. The El Nino phenomenon, which started with the weakening of the southeast trade winds, led to an abnormal increase in the water temperature in the Pacific Ocean near Peru, further affecting the ocean current system around the equator. Affected by this, the Pacific Ocean current appears 180? Rotation, heat flow did not flow from America to Asia according to the normal trend, but turned back to America, leading to rising temperature and large-scale drought.

Last year, the victim was Australia, and the El Ni? o phenomenon was more serious than usual. The temperature in all parts of Australia is rising rapidly, and the whole country is hot red on the temperature map. There is even a black area close to 50 degrees as mentioned in the title, and Tom, Dick and Harry's feet are scalded and bleeding by cement.

In fact, this 49.5 degree is the temperature at the beginning of last year. At that time, there was only extremely hot weather, and other areas were still normal. But at the end of the year, El Nino came again. This time, the highest temperature record has not been broken for the time being, but the temperature records in various places have been refreshed one after another. Such a fire is really tragic. I wonder how long this El Nino will last. If the El Nino phenomenon does not end, the high temperature in Australia will never end. Maybe it will reach 50℃ one day.
