X-band radar data sharpen simulation of westerly weak tornado

Tornadoes are among the most destructive weather phenomena on Earth. Their small scale, short life cycle and sudden onset make them extremely difficult to predict. This challenge is amplified for weak tornadoes embedded within midlatitude westerly flows, which often hide in plain sight with faint signals. Improving the simulation capability for these events is vital for reducing disaster risk in highly vulnerable regions such as the Pearl River Delta.
