紫外线指数预报

紫外线指数预报上午11：30至下午12：30之间达到地表的紫外线辐射量

The UV index forecasts the amount of ultraviolet radiation that will reach the earth 's surface from 11:30 AM to 12:30 PM

虽然你应始终针对过度暴露采取预防措施，但是在紫外线指数预报暴露级别为中度或更高时，特别注意采取阳光安全措施。

While you should always take precautions against overexposure , take special care to adopt sun safety practices when the UV index predicts exposure levels of moderate or above .

紫外线指数及其预报技术介绍

Index of ultraviolet ray and the introduction to its forecast technology

利用一般常规的辐射观测资料，通过经验公式计算紫外辐射的方法，讨论了紫外辐射强度的月际变化特征，并给出应用实例，对开展紫外线强度指数预报有一定的参考意义

A method was discussed to estimating and forecasting solar ultraviolet by use of a experience formule and the routine data of solar radiation The monthly change features of ultraviolet intensity were analyzed An example was given which has a certain sense for reference to do similar work

了解紫外线指数：当紫外线指数预报辐射级别为3（中度）或更高时

Know the UV index : when the UV Index predicts radiation levels of3 ( moderate ) or above sun safety practices should be taken

研究结果显示，模拟太阳紫外线辐射在撞击后飙升，超过了此前在地球上测量的所有紫外线辐射指数预报数据，并且会以这种状态保持两年。

UV levels in the study 's simulation soared beyond anything measured so far on Earth by the UV Index 's daily forecasts of overexposure to UV radiation , and remained that way for as long as two years .
