Our watch, however, was recently upgraded to a La Nina advisory, meaning it's here now and expected to continue.

然而，我們的手錶，最近被升級為拉尼娜諮詢，這意味著它現在在這裡，並預計將繼續。

There's an approximately 85% chance this La Nina could continue right through the months of December, January and February.

大約有85%的機率，這種拉尼娜現象會持續到12月、1月和2月。

I would say those are pretty good odds, wouldn't you?

我想說，這些都是很好的機會，你說呢？

So let's talk about what a la Nina is and how it impacts the world's weather.

所以，我們來談談什麼是 "尼娜"，以及它是如何影響世界天氣的。

Let's start in the Pacific Ocean.

我們從太平洋開始吧。

This is where the action happens during a la Nina.

這是行動發生在a la Nina期間的地方。

The trade winds, which blow from east to west, get a lot stronger.

由東向西吹的貿易風，會變強很多。

This effects both the ocean and the atmosphere in the ocean.

這對海洋和海洋中的大氣都有影響。

Warm waters get pushed to the West Pacific due to the more intense wind, allowing cool water to bubble up to the surface of the east central Pacific.

暖水由於風勢較猛，被推到西太平洋，讓冷水冒到東中太平洋的海面上。

In the air, the walker circulation gets stronger, which is the circulation of air rising over the warm waters and sinking back down over those cooler waters.

在空氣中，行屍環流會變得更強，也就是空氣在溫暖的水域上空上升，在那些涼爽的水域上空下沉。

The jet stream is reshaped as a result, changing our weather patterns.

噴流是以而重塑，改變了我們的天氣模式。

It's impacts are felt far and wide to not just in the U.

它的影響遠近聞名，不僅僅是在美國。

But around the world is to blame.

但全世界都在責備。

This year form or hurricanes in the Atlantic, flooding in Australia, you name it.

今年的形式或在大西洋的颶風，澳洲的洪水，你的名字。

You've probably heard of La Nina's brother to El Nino, which is the total opposite of a La Nina.

你可能聽說過拉尼娜與厄爾尼諾的兄弟，它與拉尼娜完全相反。

Their origins date back long ago as fishermen off the coast of South America would notice the change in ocean temperatures and the weather that would soon ensue.

它們的起源可以追溯到很久以前，因為南美洲沿海的漁民會注意到海洋溫度的變化以及很快就會隨之而來的天氣。

Researchers today, however, used the Ocean Nino index, leveraging the latest science and technology to know exactly when these will form.

不過，研究人員今天利用海洋尼諾指數，利用最新的科學技術，準確知道這些將在何時形成。
