Abstract: Severe convective weather characterizes as the small scale, short life cycle, violent weather and easy to cause casualties and property loss. In recent ten years, since the national center for severe convective weather prediction being built, the severe convective weather monitoring, now casting and outlook operations, which include the monitoring in real time, warning in 0-2 h and prediction in 72 hours for thunderstorm, short-time heavy rainfall, thunderstorm high wind and hail, have been developed, but there is now little capability to monitor and warn the smaller-scale convective weather such as tornado. China Meteorological Administration is launching the tornado warning experiment to enhance the capabilities of monitoring and warning the the disastrously severe convective weather on smaller scale and very short time range like tornado, by developing the seamless-very short range forecasting techniques which relies on the convective-available numerical models and the compositive applications of numerical weather prediction outputs and multiple observation data.
