New models can explain the causes of extreme weather formation
In recent years, the world has experienced extreme regional weather events, such as the heat waves in the united states of america in 2011 and in russia in 2010, while pakistan has experienced unprecedented flooding. According to a report of 25 february by the network of organizations of physics, the institute of climate impacts in potsdam, germany according to pik scientists, there are common reasons behind these individual disruptive climate events: man-made climate change has repeatedly disrupted atmospheric flow patterns in the northern hemisphere through an undetectable resonance mechanism. The papers will be published in the national academy of sciences journal this week. “the mid-latitude region is an important part of the global atmospheric movement, where atmospheric fluctuations can hover around the entire planet and resonate between the tropics and the arctic. When air flows up, these waves absorb hot air from the tropics to europe, russia or the united states; when they go down, the cold air from the arctic is also sent to those places.” the lead author of the paper, vladimir pitokver, explained, “we have found that the swing trajectory of these global atmospheric waves has been almost stagnant for weeks in recent extreme weather events. The last time i brought hot air, there was no cold air, so the hot air stayed there. And what we've observed is that the one that usually moves slowly in a weak condition reads the full text

New features of global extreme weather events
The year 2023 was the hottest since 1850. With record temperatures, the year witnessed frequent extreme weather events across the globe, including heat waves, extreme precipitation, rapid droughts and floods, wildfires and dust storms. In recent days, the institute of atmospheric physics of the chinese academy of sciences, in association with a number of scholars from the british meteorological service, the university of sorbonne, france, the mapu institute of meteorology, germany, the argentine institute of glacier science and environmental sciences, and the shanghai typhoon institute of the china meteorological administration, have been working in the united kingdom

Journalists learned from the institute of atmospheric physics of the chinese academy of sciences on 18 january that, following a review of the major global extreme weather events of 2023, researchers at the institute had found that a number of new features had emerged in the global extreme weather events, such as early onset, complexity, etc. Research results are published online in the journal progress in atmospheric sciences. 2023 is the hottest year since 1850. This year, all over the globe, there were frequent extremes. Days
Extreme weather is no longer an extreme event
What did professor stephen belcher, a british meteorological agency scientist, not think that he “can see a high temperature record of 40 degrees celsius in britain during his career”. Indeed, from europe to north america, the entire northern hemisphere has been hit by unusually high temperatures this summer. Scientists warned that extreme weather conditions were not only natural disasters, but also, to a large extent, man-made ones. From europe, many places, to record high temperatures faster than expected, to the increasing fire in california, united states of america..

Before that, shanghai had rained on three consecutive days, and when people thought that the fourth day, as the weather forecast said, had to cancel their outdoor activities, the university went the opposite way. For the first time in nearly 20 years, an outdoor school was held
Why are extreme weather events concentrated
More recently, the earth has seen ice caps in the northern hemisphere, the heat of the southern hemisphere's “freeze two days”, snowstorms and low temperatures on the eastern coast of the united states, freezing of the massachusetts sea waves as ice sculptors, and cooling down to “under the surface temperature of mars” in parts of the north-east, while australia in the southern hemisphere has experienced extreme temperatures, which are the highest in sydney in 79 years.

New supercomputer predicts extreme weather effects
According to zdnet, the commercial technology website of the united states broadcasting corporation (cbs), the united states has launched a new supercomputer, which can operate 53. 4 trillion times per second. The computer will predict the effects of extreme weather with the assistance of the global positioning system (gps) and other sensor technologies. The new supercomputer, named after summer, the capital of wyoming, will be installed at the national center for atmospheric research in the united states
"wood" weather model team: forecasting extreme weather futures with ai is not a dream
The recent emergence of a series of extreme weather events around the globe has seriously endangered human productive life and the need for more accurate and efficient medium- and long-term weather forecasting is increasing. In recent days, the shanghai artificial intelligence laboratory, in association with the chinese university of science and technology, shanghai transport university, nanjing university of information and engineering, the institute of atmospheric physics of the chinese academy of sciences and the shanghai center of meteorology, has launched a large global medium-term weather forecasting model, “wood”.

The response to extreme weather drainage became a “new industry”
Rainstorms in beijing, tianjin and zinan have raised concerns about underground drainage systems, while some traders have looked at the opportunities and introduced new technologies, causing drainage facilities to burn after flooding in cities. In recent days, journalists have visited some of my city's sites and have found that many of the new projects have abandoned previous brick drainage facilities and have used more sophisticated prefabricated concrete combination drainage systems

Summary of extreme weather/climate events in recent years
Against the backdrop of global warming, extreme weather/climate events, such as global floods, droughts, high temperatures, typhoons and snow and ice freezes, have intensified, especially since the 1980s, with frequent occurrence of extreme weather/climate events, resulting in disasters with severe social, economic and human impacts and losses. It is estimated that in the decade 1991-2000, the average number of people globally receiving the effects of meteorological and hydrological disasters was 211 million per year due to war
British experts say the frequency of extreme weather is rising rapidly
In an article published on 10 august by peter stoute, an expert from the british meteorological service, the recent frequency of extreme events, such as high temperatures and floods across the globe, is a direct result of unusual atmospheric activity and, while it is difficult to attribute them directly to climate change, the frequency of similar extreme events will increase significantly in the future with climate change. Stoute was the head of the british meteorological service study group on “climate monitoring and attribution” and participated in the preparation of the united nations intergovernmental panel on climate change

70% of the population or under extreme weather in the next 20 years
Norwegian scientists have found that 70 per cent of the global population may experience rapid changes in extreme temperatures and rainfall over the next 20 years in high emission scenarios. This proportion is expected to decrease to 20 per cent of the global population if robust mitigation measures are implemented to reduce greenhouse gas emissions (ssp1-2. 6). The paper was published in natural-earth science on 9 september. Continued warming is affecting extreme weather and many regions are expected in the future
Global population or experience extreme weather for the next 20 years
According to the most recent modelling study of nature earth sciences, 70 per cent of the global population may experience extreme weather in the next 20 years under high-emission scenarios. Scientists believe, however, that strong mitigation measures to reduce greenhouse gas emissions are expected to reduce to 20 per cent of the global population. Many regions are expected to experience more intense heat waves and rainfall events in the future as a result of continuing warming. But there were fewer studies in the past
