We have been watching the possibility of having to name tropical systems in the Gulf of Mexico at the same time this week.

我們一直在關注本週墨西哥灣熱帶系統不得不同時命名的可能性。

That exact scenario doesn't happen often.

這種確切的情況並不經常發生。

Actually, it's only happened two other times since records began.

其實，自記錄開始以來，只發生過兩次。

Whether Records Day, all the way back to the mid 19th century, the other occurrences were in 1959 and 1933.

無論是記錄日，一直到19世紀中葉，其他發生在1959年和1933年。

So, yeah, you could say it's been a while and there have never been to hurricanes in the Gulf of Mexico simultaneously.

所以，是的，你可以說它已經有一段時間了，從來沒有同時在墨西哥灣發生過颶風。

If we were to see two hurricanes move over those warm waters at the same time, we would surely see this huge mega behemoth hurricane form, right?

如果我們看到兩股颶風同時在那些溫暖的海水上移動，我們一定會看到這個巨大的巨獸颶風的形成吧？

You see, physics just won't allow that to happen.

你看，物理學就是不允許這種情況發生。

Hurricanes have both a counterclockwise rotation.

At one level, we call this cyclonic spin, and at another level they have a clockwise rotation known as anti cyclonic spin.

在一個層面上，我們稱之為旋風自轉，而在另一個層面上，它們的順時針旋轉被稱為反旋風自轉。

These opposing spins prevent two hurricanes from congealing into a super hurricane.

這些對立的旋轉防止了兩個颶風凝結成一個超級颶風。

It's like trying to force the same ends of a magnet to attract It won't happen.

這就像試圖迫使磁鐵的相同端吸引一樣，這是不可能的。

So is the same with two hurricanes, also under certain rare situations, something known as the Fuji War effect will occur.

兩次颶風也是如此，也是在某些罕見的情況下，會出現所謂的富士戰效應。

It's a meteorological phenomenon discovered in the early 19 twenties, and it says when two hurricanes get within a certain proximity of each other, the two will begin revolving in a circle again.

這是1920年代初發現的一種氣象現象，它說當兩個颶風相距一定距離時，兩個颶風又會開始轉圈。

Imagine two magnets, repelling and bouncing off each other.

想象一下，兩塊磁鐵，相互排斥，相互反彈。

If the to get closer and closer, the stronger hurricane will cause a smaller one toe weakened.

如果離得越來越近，較強的颶風就會造成較小的一趾減弱。

If the two are similar in strength, both will weaken.

如果兩者實力相近，都會有所削弱。

So the one thing you will not get out of it is a mega hurricane forming.

所以，你不會得到的就是一個特大颶風的形成。

 That's at least one less thing for you worry about this year. 

這至少讓你今年少了一件擔心的事情。
