Free Every Day The Sun Doesn't Shine on St.

太陽不照耀聖城的每一天》免費

This is a newspaper ad from 1910, and it made a promise that they called the Sunshine Offer.

這是 1910 年的一則報紙廣告，其中做出了一項承諾，他們稱之為 "陽光優惠"。

Sunshine Offer said that anytime the sun failed to come out, if you had a subscription, you were a customer, you were a stranger, it didn't matter, you would get the next day's newspaper for free.

陽光報》說，只要太陽不出來，只要你訂閱了報紙，不管你是顧客還是陌生人，都可以免費得到第二天的報紙。

They printed this promise in their papers and made postcards advertising this deal, this bet against bad weather, advertising a sunshine city.

他們在報紙上刊登了這一承諾，還製作了明信片，宣傳這一交易，宣傳這一與惡劣天氣的賭注，宣傳一座陽光之城。

And this reputation persists to this day.

Local Reddit threads question the mysterious and unsettling lack of rain, and the city even holds the Guinness World Record for the longest stretch of consecutive sunny days at 768 during the late 1960s.

當地 Reddit 上的帖子對神祕而令人不安的少雨現象提出了質疑，而這座城市甚至還保持著金氏世界紀錄，即在 20 世紀 60 年代末，連續晴天最長達 768 天。

Today, it's pretty easy to find out that in the summertime, St.

今天，我們很容易就能發現，在夏季，聖弗朗西斯-聖彼得堡是一個充滿活力的城市。

Pete gets more rain than Seattle, a reputationally rainy city.

皮特的雨水比西雅圖還多，而西雅圖是一個以多雨著稱的城市。

那麼，這兩件事怎麼可能都是真的呢？

And if not, why does it have this reputation?

如果不是，為什麼會有這樣的名聲？

Okay, it's probably a good time to mention this up front.

好吧，現在也許是時候先提一下這個問題了。

本視頻由聖彼得堡旅遊局贊助。

However, we honestly might've ended up making it anyways.

不過，老實說，我們最後可能還是成功了。

Petersburg holds the world record for 768 straight days of consecutive sunshine, I basically assumed it was some kind of myth.

彼得堡保持著連續 768 天日照的世界紀錄，我基本上以為這是某種神話。

This video is going to try to explain the meteorological conditions that contribute to this seemingly eternal sunshine in this Goldilocks region of Florida.  And if along the way you get a feel for what it's like to visit a place where the sun never takes a day off, where you get calm, jewel-toned beaches, a thriving art scene, and a downtown that's just as good for a night out as it is for museum day, well, that's good too.

這段視頻將試圖解釋佛羅里達州這個金髮姑娘地區看似永恆陽光的氣象條件。  如果您在觀看的過程中感受到，在這個陽光普照的地方，您可以享受到平靜的寶石色海灘、繁榮的藝術氛圍，以及既適合晚上外出又適合白天參觀博物館的市中心，那麼，這也是一件好事。

In this video, we're gonna look at some of what makes St.

在本視頻中，我們將瞭解聖彼得堡的一些特點。

Pete sunny, but it's important to start off here by saying that the weather is complex and varied.

皮特陽光明媚，但首先要說明的是，天氣是複雜多變的。

When you zoom out and look at other places that share Florida's latitude on the map, it's where some of the world's most famous deserts are.

放大地圖，看看與佛羅里達州緯度相同的其他地方，世界上一些最著名的沙漠就在那裡。

And that has a lot to do with air pressure.

So if we start from the biggest picture possible, which is the globe, and the sun shines down upon the earth, well, it shines upon the equator more than it does the poles.

是以，如果我們從儘可能大的畫面出發，也就是地球儀，太陽照耀著地球，那麼，它照耀赤道的程度要比照耀兩極的程度大。

這使空氣變暖，導致空氣上升。

Eventually, it hits the stratosphere, which acts as a sort of ceiling.

最後，它進入平流層，平流層就像一個天花板。

And with nowhere left to rise, it pushes outward.

在無處上升的情況下，它向外推進。

And the further it gets from the surface of the earth and the equator, the cooler the air becomes.

離地球表面和赤道越遠，空氣就越冷。

As it cools, it sinks, and the process repeats.

冷卻後，它就會下沉，這個過程不斷重複。

不管怎麼說，這只是一個簡單的版本。

Because the earth spins, that means the air goes up at the equator, and it does go north, but it also turns about 30 degrees north.

由於地球自轉，這意味著空氣在赤道上升，確實會向北飛，但也會向北轉 30 度左右。

So by the equator, there's a band of rising air all around the equator all year around.

是以，在赤道附近，全年都有一條上升空氣帶。

You can think of the air sort of like a sponge.

As it gets heated, it expands, picks up moisture, and rises.

當它受熱時，會膨脹、吸溼並上升。

And at a certain point, that squeeze becomes enough that it can't hold moisture anymore, and it rains.

到了一定程度，這種擠壓就會變得足夠大，無法再保持水分，於是就會下雨。

Globally speaking, the equatorial effect of rising and sinking air dictates where rainfall usually occurs or doesn't.

從全球來看，空氣上升和下沉的赤道效應決定了降雨通常在哪裡發生或不在哪裡發生。

And Florida, at right around 30 degrees, is in the dry band, where rain usually doesn't occur.

而佛羅里達州的氣溫在 30 度左右，屬於乾燥帶，通常不會下雨。

So it should be a desert, but it's not, partly because it's surrounded by water.

是以，它應該是一片沙漠，但事實並非如此，部分原因是它四面環水。

Petersburg is here, on a tiny peninsula within the bigger peninsula of Florida.

彼得斯堡就在這裡，位於佛羅里達州大半島中的一個小半島上。

And having land and water so close to each other is great for making storms.

陸地和水域如此接近，是製造風暴的好地方。

The land can heat up a lot faster than the ocean does.

陸地升溫的速度比海洋快得多。

That temperature difference sets up a pressure difference.

So hot air from above the land rises, and cooler air from above the ocean flows in to replace it.

是以，陸地上空的熱空氣上升，海洋上空的冷空氣流入取而代之。

That breeze means that the sky above the ocean is generally spotless, while clouds tend to form above the land, and those clouds flow further inland due to the sea breeze.

海風意味著海洋上方的天空通常一塵不染，而陸地上方往往會形成雲層，這些雲層在海風的吹拂下向內陸流動。

Rain is typically going to fall inland from the beach.

So it's very often that your beach holiday is going to be just fine and sunny, but maybe somewhere further inland got storms in that afternoon.

是以，經常會出現這樣的情況：你的海灘假期陽光明媚，但也許在更內陸的某個地方，當天下午就下起了暴風雨。

Because Florida is surrounded by water, this effect occurs on both coasts, causing these opposing sea breezes to converge.

由於佛羅里達州四面環水，這種效應發生在兩岸，導致這些對立的海風匯聚在一起。

So if you look at the coasts of Florida, the Atlantic coast is fairly straight.

是以，如果你看看佛羅里達州的海岸，大西洋沿岸相當平直。

So because of that, all of the sea breeze storms on that coast is just a few miles inland of the entire coast.

正因為如此，海岸上所有的海風暴雨都在整個海岸內陸幾英里的地方。

But when you look at the Gulf side, if you connect the coast from Cedar Key to about the Naples and Fort Myers area, that forms about a straight line where the sea breeze thunderstorms typically form.

但是，如果你看看海灣一側，如果你把海岸線從錫達基連接到大約那不勒斯和邁爾斯堡地區，這就形成了一條直線，海風雷暴通常就在這裡形成。

Pete happens to jut out just far enough from the rest of Florida that it ends up in this sort of Goldilocks region, where a lot of the clouds blow past them before their sponge squeeze effect turns moisture into rain.

皮特恰好與佛羅里達州其他地區相距足夠遠，是以它最終處於這種 "金髮女郎 "地區，在海綿擠壓效應將水汽轉化為雨水之前，很多雲都會從這裡吹過。

The combination of the sea breeze structure with the geography absolutely means that St.

海風結構與地理環境的結合絕對意味著聖馬丁島將成為世界上最美麗的島嶼之一。

Petersburg is set up meteorologically to have more sunny days than some of its neighbors, either up and down the coast or further inland.

從氣象學角度看，彼得堡的晴天要多於一些鄰近地區，無論是沿海還是內陸地區。

Where most people hear about the Bermuda High is in relation to hurricanes.

大多數人都聽說過百慕大高原與颶風有關。

It's a pressure system that grows and shrinks in the Atlantic, and it has the potential to steer bigger storms, like hurricanes, away from Florida and up the East Coast.

它是一個在大西洋上時大時小的氣壓系統，有可能引導更大的風暴（如颶風）遠離佛羅里達，向東海岸移動。

皮特，聖彼得堡的大部分時間都是在

Petersburg gets affected by a hurricane, it's either coming from the Atlantic and across the peninsula, or from the South and coming up the peninsula.

彼得堡受到颶風影響時，颶風要麼來自大西洋，橫穿半島，要麼來自南方，從半島上來。

And as we learned last year, it's not impossible for storms to go directly into the city, like it did with Hurricane Milton in 2024.

正如我們去年所瞭解到的，風暴直接進入城市並非不可能，就像 2024 年的颶風米爾頓一樣。

This storm dropped a whopping five inches of rain on St.

這場暴風雨給聖馬丁島帶來了高達五英寸的降雨量。

It is extremely unusual for any location to get five inches of rain in an hour.

任何地方在一小時內降雨量達到五英寸都是極不尋常的。

Petersburg was in the North side of the eye wall.

And because of all of the atmospheric effects and the environment that it was in, it amplified the amount of rainfall that was on the North side.

由於大氣層的影響和所處的環境，北側的降雨量被放大了。

However, in the 175 years before that, the area has really only had two other major hurricanes, in 1848 and 1921.

不過，在此之前的 175 年裡，該地區真正遭遇過的大颶風只有 1848 年和 1921 年兩次。

Let's go back to this chart, comparing the average monthly rainfall of St.

讓我們回到這張圖表，比較一下聖馬丁島的月平均降雨量。

Petersburg looks pretty rainy comparatively.

相比之下，彼得堡看起來雨水還真不少。

But here's the thing, more rain doesn't always mean less sunshine.

但問題是，雨水多並不總是意味著陽光少。

When it comes to Florida, very warm temperatures means that more water vapor can evaporate into the air, which means that when it does rain, it tends to rain a lot and very heavy and all at once.

在佛羅里達州，氣溫很高意味著有更多的水蒸氣可以蒸發到空氣中，這就意味著一旦下雨，雨往往會下得很大，而且一下子就下得很猛。

In contrast to that is a place like Seattle, which is on the Northwest side of a continent.

與之形成鮮明對比的是像西雅圖這樣位於大陸西北側的地方。

And so just offshore, it has very cold oceans.

是以，就在近海，這裡有非常寒冷的海洋。

And when it does evaporate, you wind up with overcast conditions.

一旦蒸發，就會出現陰霾天氣。

Even though it's raining a lot of days, they only get about 30 inches of rain per year.

儘管很多時候都在下雨，但他們每年的降雨量只有 30 英寸左右。

Whereas it is not out of the question at all for the Florida Peninsula to get 40 or 50 inches of rain in the year, even though we consider ourselves, rightly, a very sunny place.

儘管我們認為自己是一個陽光充足的地方，但佛羅里達半島一年下四五十英寸的雨也不是不可能的。

Pete History Museum, I found this postcard that mentioned that the cutoff for the evening post was the sun not shining before 2 p.m.

在皮特歷史博物館，我發現了這張明信片，上面提到晚郵的截止時間是下午 2 點之前沒有太陽。

And a representative from the Guinness World Records emailed me to explain that, while they can't judge yesterday's achievements by current standards, their definition of a sunny day is now aligned with the National Weather Service, which says that clear slash sunny is a sky condition with 1 8th or less of opaque cloud coverage. 768 days sounds like a little bit of fudging, but from a meteorological perspective, you're starting to think about stats and how do we quantify the sunny day.

金氏世界紀錄的一位代表給我發來郵件解釋說，雖然他們不能用現在的標準來評判昨天的成就，但他們對晴天的定義現在與美國國家氣象局一致，即不透明雲層覆蓋率在 1/8 以下的天空為晴天。768 天聽起來有點弄虛作假，但從氣象學的角度來看，你已經開始考慮統計以及如何量化晴天了。

In that sense, we're thinking about what was it overall between sunrise and sunset, not did it just rain at all.

從這個意義上說，我們考慮的是日出和日落之間的總體情況，而不是下雨。

Well, in that case, if it rains only 10 minutes, it was still sunny for the majority of the day.

這樣的話，如果只下 10 分鐘雨，一天中的大部分時間還是晴天。

所以，平均來說，今天還是個晴天。

Separating marketing from reality can be challenging, but in the 78 years of the Evening Independence Life, they only gave out 296 free copies.

將營銷與現實區分開來可能很有難度，但在《獨立生活晚報》創刊的 78 年裡，他們只免費發放了 296 份。

You think nearly 300 newspapers, but really think about this, that equates to only about six rainy or cloudy days per year that he was required to give it away.

你以為有近 300 份報紙，但仔細想想，這相當於每年只有大約 6 個陰雨天，他必須把報紙送出去。

The original ad declared that the nearest approach to perpetual sunshine in the whole United States is at St.

最初的廣告宣稱，在整個美國，最接近永恆陽光的地方是聖馬丁。
