The latest achievements of National Marine Laboratory: the frequent occurrence of heavy haze is related to global warming

in recent years, haze has been the focus of social attention. Recently, the latest research results of Qingdao National Laboratory of marine science and Technology (hereinafter referred to as "Qingdao National Laboratory of marine science and technology") show that global warming has led to an increase in the frequency of severe haze weather, and in the climate warming environment, the frequency and duration of meteorological conditions that are not conducive to the rapid spread of haze have increased by 50% and 80% respectively over the last century

global warming leads to frequent occurrence of severe haze

on March 20, the internationally renowned academic journal nature climate change published the latest research results entitled "weather conditions induce to Beijing severe haze more frequent under climate change". This achievement was jointly completed by the scientific research team with caiwenju, the leading scientist of the National Oceanic laboratory and part-time professor of Ocean University of China as the first author, and Wu Lixin, the director of the National Oceanic laboratory and academician of Ocean University of China as the co-author. The report points out that global warming has led to an increase in the frequency of severe haze weather conditions in Beijing, highlighting the international frontier position of the National Marine Laboratory in the field of climate change research

adverse weather conditions are also the cause of haze

on March 21, National Marine Laboratory held a press conference to introduce the latest research results. "When winter haze weather occurs in Beijing, the surface north wind and the mid tropospheric northwest wind weaken, accompanied by an increase in the stability of the lower atmosphere, which leads to weather conditions that are very unfavorable for the rapid spread of haze, making its accumulation further develop into severe haze." At the press conference, caiwenju said that although it is generally believed that pollution emissions are the culprit of haze, the influence of weather factors can not be ignored in more than half a year

according to the research results, under the climate warming scenario, the frequency and duration of stable meteorological conditions that are not conducive to haze diffusion have increased by 50% and 80% respectively over the last century. This change is closely related to a series of changes in the atmospheric background field, such as the rapid warming of the lower atmosphere caused by global warming and the weakening of the East Asian winter monsoon, which will greatly increase the frequency of severe haze events in Beijing in winter. The weakening of the East Asian Winter Monsoon caused by global warming is due to the weakening of the sea land temperature in winter, so it is necessary to know that the operation strategy of the granulator is 10 points. The huge heat capacity of the ocean makes the growth rate of SST much slower than that of land temperature. At the same time, the complex circulation transportation system in the Western Pacific and offshore China plays an important role in regulating SST in this region

haze control requires global joint action

the report points out that haze control requires global joint action. The National Marine Laboratory is the first National Laboratory approved for pilot operation in China. It is an important organization that faces major national strategic needs, reflects the national will, optimizes the allocation of global scientific and technological resources, and carries out collaborative innovation. At present, the National Marine Laboratory is implementing major scientific plans such as "transparent two oceans and one sea" to provide scientific support for the refined prediction of marine environment and climate change. At the same time, the laboratory is cooperating with the National Center for Atmospheric Sciences (NCAR), the National Oceanic and Atmospheric Administration (NOAA)/Ambassador Princeton to greatly broaden the scope of the experiment. The laboratory of geodynamics and Texas A & M University are preparing to build the International Research Center for ocean and climate prediction. With the international leading ultra-high performance computing platform of the National Marine Laboratory, Achieve ultra-high resolution prediction of marine environment and climate in the coming decades

with the increasingly close collaborative demand in the scientific research field, the National Marine Laboratory has actively made due contributions to the global climate change research with the help of its own comprehensive collaborative innovation platform. Pan Kehou, Secretary General of the Science Committee of the National Marine Laboratory, said that the national marine laboratory will continue to actively explore and solve scientific problems related to China's people's livelihood. At the same time, the governance of haze is common to all countries in the world. The national marine laboratory should contribute its own strength, lead and promote world cooperation with scientific research institutions in other countries and regions in the fields of climate research, and contribute wisdom and strength to environmental improvement and the construction of ecological civilization
