The main weather prediction system used worldwide-numerical weather modeling-incorporates data from land, air, and sea monitoring around the globe. Along with other estimated values, these data are entered into a supercomputer which crunches the numbers and extrapolates future changes in the weather system.
目前全世界主要的天氣預報系統──數值天氣預報模式，是以全球的地面、高空及海洋等氣象觀測資料，以及其他猜測數值，輸入超級電腦運算、推估天氣系統的未來演變。
