well, you hear us talk a lot about the models, the European versus the American, and how are they different?

好了，你聽到我們談了很多關於模型， 歐洲與美國，他們有什麼不同？

to 不定詞

We're trying to model an atmosphere that has an infinite number of layers from where we live.

我們正在嘗試模擬一個大氣層，從我們生活的地方有無限多的層數。

To the top of the atmosphere is not 9 12 13 different layers.

到大氣層的頂部不是9 12 13不同的層次。

It's an infinite number, but you can't put infinity into a computer and expect an answer because it will just hang up and keep running.

這是一個無限大的數字，但你不能把無限大的數字放進電腦裡，然後指望得到答案，因為它只會掛掉，繼續運行。

The difference between the two models is trying to get a model run that's accurate and timely, timely meaning.

兩種模式的區別就是想讓模型運行的準確和及時，及時的意思。

We can have a perfect forecast for a two day snowstorm, but it might take 24 hours worth of running the computer to get there.

我們可以對兩天的暴風雪有一個完美的預報，但可能需要運行24小時的電腦才能達到目的。

So it's a two day forecast that's only good for one day.

所以，這兩天的預報，只能用一天。

We try to get it to run in four hours or less.

我們儘量讓它在四個小時內運行。

Now the European model does take longer to run.

現在歐洲模式確實需要更長的時間來運行。

There's more data in the European model, and so therefore, it can be slightly more accurate.

歐洲模式的數據比較多，所以，可以稍微準確一些。

 But the American model is pretty close.
