In the early part of 2020, we have been worried about whether there will be an El Niño in 2020, because the appearance of El Niño may bring about abnormal temperature changes, such as the temperature of the Earth, which may affect both land and marine areas.
From the latest observation data, the El Niño monitoring area has shown a significant decline, but has not changed the overall warming trend, and now it is located at about +0.4 degrees, so the downward trend has gradually emerged, but in a short period of time, it may not be seen whether it will rise again, and it can only be observed. And most institutions are not optimistic about the emergence of 2020, basically saying that the probability is very low, but the abnormal temperature may be a lot.
According to the World Meteorological Organization, due to climate change caused by human activities in 2020, many parts of the world will still experience abnormal high temperatures, so high temperatures will appear significantly, and "big heat" in many parts of the world in 2020 may be basically a foregone conclusion. And from the trend of 2019, we can also see that they have reached the second highest temperature year in history, and the first few months of 2020 have also set a record, so it is worth noting that 2020 may heat up to new heights.
And meteorologists have called 2020 or the hottest year in history, and all even without El Niño, there could be a breakthrough in historic heat. This is the climate change caused by human activity, and the abnormal weather is really getting hotter and hotter, as scientists predicted, and the earth is on fire.
If human beings want to change this climate state, they may only be able to reduce greenhouse gas emissions in the future, and if it continues, we may still be hurt.
And now we have arrived in May, it can be said that in the meteorological sense or spring, but now many areas of our country have appeared high temperature weather, of which during the May Day holiday, most of the northern regions are "temperature soaring" mode, of which on the first day of May Day, China's North China, Jilin, Liaoning and other places a total of 123 stations the temperature reached or exceeded the historical extremes in early May, of which 43 stations temperature more than 35 ° C, this is deterministic data, Among them, Zhuolu (38.5 °C) and Chicheng (35.6 °C) in Zhangjiakou, Hebei Province, broke through the historical extremes in May.
Statistics from 15:00 on May 2 show that data from 2418 national meteorological observation stations show that among the top 10 high temperature rankings in the country, 9 high temperature areas are Henan, the highest is Henan Yichuan reached 39 degrees, and in the top 10, the lowest temperature is 37.5 degrees, which is really too hot. So the temperature in the northern region is really too high. At the same time, high temperature warnings have also appeared in some provinces and cities.
According to the authoritative forecast of the Meteorological Center, it is estimated that by the 4th, the high temperature range will be significantly reduced, and there will be a situation of southern pressure, so the north is hot, and parts of the south may also be hotter. In fact, there are hot areas in the southwest region today, such as Sichuan and other places, and there are also rare high temperature phenomena, and it is almost "sweaty" when going out.
Therefore, in terms of time, if it is hot for another day, the high temperature will be significantly alleviated, and the temperature in some parts of the north will fall, and it is more obvious, of which the cooling range in Parts of Inner Mongolia, the central and southern parts of the northeast region and Shanxi can reach more than 10 °C.
For example, xin'an, which has a relatively high temperature on the 2nd, on May 3, the maximum temperature cooled to 38.5 degrees, and on May 4, the maximum temperature was only 23.2 degrees, so the local cooling in the north will reach more than 15 degrees, of course, this is today's forecast, there may be changes in the later stage, and I will continue to follow up. Is there no rain in such a hot weather? Of course, in the next week or so, there will also be obvious rainfall, in the 6-9th, China will have a large-scale rainfall process, generally small to moderate rain mainly.
The strongest rainfall is distributed in parts of Jiangnan, the eastern part of the Sichuan Basin and other places have heavy rain or heavy rain, from the medium-term rain forecast can also be clearly seen, in Hunan, Jiangxi and other places in most parts of the cumulative rainfall have 100 mm to 250 mm, and Fujian, Guizhou and other areas also have 50 mm to 100 mm of cumulative rainfall, so the rain is still there, but now it is still dominated by high temperatures.
That's the next weather change. The change in the marine area is not much, although the European and American meteorological agencies are still forecasting the 94W typhoon embryo, but the possibility of becoming a typhoon is extremely low, the typhoon embryo has been gradually moving westward, which may affect the Philippines, and then enter the development of the South China Sea, on the whole, if there is a change in the later stage, we will look at it again to see if it will bring a wave of rain to our country.
