Reported by China Meteorological News reporter Zhang Guangmei Recently, the Northeast Cold Vortex Research Open Key Laboratory was formally established and started operation. The laboratory focuses on the Northeast cold vortex system that causes complex catastrophic weather such as low temperature cold damage, continuous rain and flood, and strong convection in Northeast China, and the frequent occurrence of extreme weather and climatic events such as heavy rain, snowstorm, drought, low temperature, and fog-haze in Northeast China. The research and development of typical weather systems such as the mid-high latitude multi-climate climate system in the Northeast region is aimed at improving the level of weather forecasting and forecasting operations in Northeast China, strengthening the capabilities of disaster prevention and mitigation in Northeast China, food security, and meteorological support for ecological civilization. Quality weather guarantee.

The research and development team of the Northeast Cold Vortex Research Open Key Laboratory is based on the Shenyang Institute of Atmospheric Environment of China Meteorological Administration and related scientific research staff in Liaoning, Jilin, and Heilongjiang provinces, and is complemented by the Institute of Atmospheric Physics of the Chinese Academy of Sciences, the Chinese Academy of Meteorological Sciences, and the National Meteorological Center. Relevant scientific research forces at home and abroad, such as Nanjing University of Information Science and Technology, and universities, are mainly aimed at the impact mechanism of Northeast cold vortex on the climate in East Asia and the technology of forecasting climate anomalies, the mechanism of strong convective weather caused by the cold vortex in Northeast China and the forecast and early warning technology, and the typical severe weather in Northeast China. The research is carried out in the fields of mechanism, forecast and early warning technology, and high-resolution numerical model system data assimilation technology in Northeast China.

The laboratory will also build a scientific experimental base for strong convection observation of the cold vortex in the Northeast. The test base can carry out scientific observations of the meso- and small-scale strong convective weather system of the cold vortex in Northeast China, and study the three-dimensional structure evolution characteristics of the meso- and small-scale system of the strong convection in the Northeast cold vortex and the mutual feedback mechanism with the weather scale system. The northeast cold vortex induces local heavy rain, hail, gale, dragon The strong convective weather mechanism and forecasting and early-warning methods, such as volume, continue to improve the refined objective forecasting and early-warning methods for high-impact weather in the Northeast, and to improve the accuracy of forecasting and early-warning in cold vortex weather systems in the Northeast.
