随着科学的发展和人类的需要,现在天气预报又增加了紫外线辐射指数预报的最新项目。美国国家气象局首先作了尝试。具体做法是,在每日天气预报节目中对美国58个城市的紫外线辐射量同时作出预报。报出第二天它的最大辐射量,帮助人们免受太阳光的伤害。据研究,290～320毫微米的中波紫外线主要使皮肤发生日晒伤(日光性皮炎);320～400亳微米的长波紫外线主要使皮肤晒黑(色素增加)和引发雀斑。紫外线辐射还会抑制人体
With the development of science and the needs of mankind, the weather forecast now adds the latest project of UV radiation index forecast. The United States National Weather Service first tried. The specific approach is to simultaneously forecast the amount of ultraviolet radiation in 58 cities in the United States in the daily weather forecast program. Reported on the second day of its maximum radiation, helping people to protect themselves from the sun. According to research, 290-320nm UVB mainly causes sunburn (solar dermatitis) on the skin; 320-400μm UVA mainly causes the skin to tanning (increases pigment) and causes freckles. Ultraviolet radiation also suppresses the body
