The State Key Laboratory of Disastrous Weather, with the goal of supporting the national meteorological science and operational technology for disaster weather monitoring and prediction, carries out basic and applied basic research, and focuses on the scientific frontier issues to improve the capability of disaster weather monitoring and prediction,developTheoretical research on disaster weather dynamics with the formation mechanism of disaster weather as the main content, new theory and new technology research on disaster weather monitoring with the development of radar quantitative remote sensing as the main content, new theory and new technology research on disaster weather prediction with the development of short-term fine and quantitative numerical forecasting as the main content, and committed to the business application of laboratory research results.
State Key Laboratory of Disaster Weatherrely onChina Academy of Meteorological Sciences。The disastrous weather, such as rainstorm, typhoon, low temperature, snow and freezing, has brought huge losses to our national economy and people's lives and property.The increase of China's economic aggregate and population density, on the one hand, makes the impact of meteorological disasters become more and more serious, seriously affecting the development of China's national economy and the safety of people's lives and property, on the other hand, the social impact onMeteorological forecastThe requirement of accuracy is getting higher and higher.
Therefore, improving the ability of monitoring and forecasting disaster weather is a major national demand.However, the weather systems that directly cause meteorological disasters are mainly mesoscale systems or mesoscale disturbances with a spatial scale of only tens of kilometers to one or two hundred kilometers and a time scale of only a few hours to ten hours.Due to the limitation of observation ability, our understanding and understanding of the mesoscale system of disastrous weather is not deep enough, and the fine forecasting ability is far from meeting the national needs, which has become one of the important issues affecting the development of national meteorological operations.
Therefore, the research purpose of the State Key Laboratory of Disaster Weather is to study the monitoring, mechanism and forecasting methods of mesoscale disaster weather,increaseThe country's ability and level of monitoring and forecasting disaster weather provide technical support for the development of national meteorological operations.
