During mid and late February of 2024,a strong cold surge,dust storm and various freezing weathers(snowstorm,sleet,freezing rain,rainstorm and severe convection producing large hail and dama-ging gust),associated with severe convection to the south,occurred in a large area over China.Multiple high-impact-weather events showed up during this extreme complicated process.In order to provide an in-troduction for the subsequent detailed and in-depth analysis and research of this process,in this article we discuss briefly the mechanisms and forecasting challenges of these high-impact-weather events,without ex-ploration in details and in depth.
