What does the maximum ultraviolet wind 10 meter mean?

The UV index value reaches or exceeds 10.

The maximum ultraviolet wind 10m indicates that the ultraviolet index value reaches or exceeds10.

The UV index generally starts from 0 and ends at 10 (including 10 or above). According to these values, the Meteorological Bureau divides the forecast grade of ultraviolet index into five grades. The ultraviolet index value is 0 to 2, usually cloudy or rainy, when the ultraviolet intensity is the weakest, and the forecast level is 1. The ultraviolet index value is 3 to 4, and it is generally cloudy. At this time, the ultraviolet intensity is weak, and the forecast level is Grade II. The ultraviolet index value is 5 to 6, which is generally partly cloudy. At this time, the ultraviolet intensity is strong, and the forecast level is level 3. The ultraviolet index value is 7 to 9, and it is generally clear and cloudless. At this time, the ultraviolet intensity is very strong, and the forecast level is 4. The ultraviolet index value reaches or exceeds 10, and it is mostly sunny in summer, and the ultraviolet intensity is particularly strong. The forecast level is five.
