2019年秋季觀葉指南

As the temperature drops and autumn sets in, Mother Nature is painting the treetops in vibrant hues of red, orange and gold, and many people are planning their leaf-viewing vacations.

隨著氣溫的下降和秋天的來臨，大自然母親把樹梢涂成鮮艷的紅色、橙色和金色，許多人都在計劃賞葉度假。

SmokyMountains.com created a prediction map for the year's fall colors using millions of historical data points from the National Oceanic and Atmospheric Administration (NOAA).

SmokyMountains.com網(wǎng)站利用美國國家海洋和大氣管理局(NOAA)的數(shù)百萬個歷史數(shù)據(jù)點，為今年的秋季色彩繪制了一張預測地圖。

"The predictive fall leaf map helps potential travelers, photographers and leaf peepers determine the precise future date that the leaves will peak in each area of the continental United States," Wes Melton, a data scientist and CTO of SmokyMountains.com, told Travel + Leisure.

SmokyMountains.com網(wǎng)站的數(shù)據(jù)科學家兼首席技術官韋斯·梅爾頓(Wes Melton)在接受《旅游+休閑》(Travel + Leisure)采訪時表示:“這種預測秋葉圖可以幫助潛在的旅行者、攝影師和賞葉者確定未來樹葉在美國大陸每個地區(qū)達到頂峰的準確日期。”

"We believe this interactive tool will enable travelers to take more meaningful fall vacations, capture beautiful fall photos and enjoy the natural beauty of autumn," said Melton.

梅爾頓說:“我們相信，這個互動工具能讓游客們度過更有意義的秋季假期，捕捉美麗的秋季照片，享受秋天的自然美景。”

The color change of the leaves depends more on light than temperature, so it takes place at about the same time each year. But temperature, rain and other weather conditions can have an impact on the timing of the leaves' changing color. Thanks to warmer-than-average temperatures, fall is taking longer to come around for 2019. The good news is, with much of the U.S. having had an unusually wet summer, the tree are healthy and happy.

樹葉的顏色變化更多地依賴于光而不是溫度，所以每年大約在同一時間發(fā)生。但是溫度、降雨和其他天氣條件會影響樹葉變色的時間。由于氣溫高于平均水平，2019年秋季的到來需要更長的時間。好消息是，由于美國大部分地區(qū)經(jīng)歷了一個異常潮濕的夏天，這棵樹健康而快樂。

Here's a look at what to expect this fall if you're looking for colorful foliage.

如果你正在尋找五彩繽紛的樹葉，下面就讓我們一起來看看這個秋天會發(fā)生什么吧。

Northeast

東北部

Peak time: There are a few patchy areas in the Northeast where leaves have already started to change, per SmokyMountains.com's map. The region may be at or near its peak by early October, and it'll be past its peak by late in the month. Fall foliage tends to peak for about one week around October 5th in Vermont, whereas the northern parts of New York and Vermont will be past their peak by mid-October.

高峰時間:據(jù)SmokyMountains.com網(wǎng)站的地圖顯示，美國東北部有幾個零星地區(qū)的樹葉已經(jīng)開始發(fā)生變化。該地區(qū)可能在10月初達到或接近峰值，并將在本月末超過峰值。在佛蒙特州，秋天的樹葉通常在10月5日左右達到一個星期的高峰，而紐約和佛蒙特州的北部地區(qū)將在10月中旬達到高峰。

Southeast

東南部

Peak time: Some parts of the Southeast will have minimal to patchy color changes by the middle of October. The leaves are changing in North Carolina around November 2nd, but for peak foliage, aim to head outside around November 9th. If you give it a few more weeks, swatches of Virginia and Tennessee will be at their peaks. However, most of the region won't start to peak until early November, with the southernmost areas not peaking until the middle of the month.

高峰時間:到10月中旬，東南部部分地區(qū)的顏色變化將是最小的，甚至是零星的。北卡羅萊納的樹葉在11月2日左右會發(fā)生變化，但如果是樹葉的高峰期，最好在11月9日左右出門。如果你再給它幾周的時間，維吉尼亞州和田納西州的部分地區(qū)將會達到頂峰。不過，該地區(qū)的大部分地區(qū)要到11月初才會開始見頂，最南端的地區(qū)要到本月中旬才會見頂。

Midwest

中西部

Peak time: The northern portions of Michigan, Wisconsin and Minnesota — will peak by early October. The rest of the region is expected to peak later in October.

高峰時間:密西根州、威斯康辛州和明尼蘇達州的北部地區(qū)將在10月初達到高峰。該地區(qū)其他地區(qū)預計將在10月晚些時候達到峰值。

Central U.S.

美國中部

Peak time: The northernmost states in the region won't begin to really change up the colors until near the middle of October. Texas' leaves will change from November 16th through the end of November. In the northern part of the Lone Star State, you might see them at peak as early as November 9th.

高峰時間:該地區(qū)最北部的州要到10月中旬才會真正開始改變顏色。從11月16日到11月底，德州的假期將會改變。在孤星州的北部，你可能在11月9日就能看到它們的高峰。

Northwest

西北部

Peak time: The leaves will start to visibly change in Washington state around October 1st, and peak around October 12th. You may be able to see peak foliage as late as October 26th in southern parts of the region.

高峰時間:華盛頓州的樹葉將在10月1日左右開始明顯變化，10月12日左右達到高峰。在該地區(qū)的南部，你可能會在10月26日晚些時候看到樹葉的高峰。

West and Southwest

西部和西南地區(qū)

Peak time: Northern California will see the peak of the season from about October 26th through November 9th. If you're down south, plan to head out November 9th through mid-November. Some parts of the Mountain West are already receiving their first snow of the season, which will dampen fall foliage.

高峰時間:北加州將在10月26日到11月9日之間迎來這個季節(jié)的高峰。如果你在南方，計劃11月9日到11月中旬出門。西部山區(qū)的一些地區(qū)已經(jīng)迎來了這個季節(jié)的第一場雪，這將抑制秋天的樹葉。
