Meteorologists then run the data through predictive physics models that generate the final weather forecast.

气象学家再用预报物理模式跑数据，产生最终的天气预报。

Basically, something like fur has potentially millions of hairs, which can't be individually animated, so physics models have to be built to simulate their motion.

基本上，毛发这样的东西很可能有数百万根，无法每根都单独处理，所以模型必须要能模拟它们运动的样子。
