1
There are three basic stages in the life of a tropical cyclone,
2
its origin or source, the mature stage and the dissipation stage,
3
where it dies out.
4
These occur in a continuous process,
5
not as separate and distinct stages.
6
Each stage may occur more than once during the life cycle,
7
as the strength of the cyclone rises and falls.
8
it may reach land, weaken,
9
then go back out to sea where it strengthens once more.
10
The formation of a cyclone depends upon the following conditions coinciding.
11
A large, still and warm ocean area with a surface temperature that exceeds 26.5 degrees Celsius over an extended period.
12
This allows a body of warm air to develop above the ocean's surface surface.
13
Low altitude winds are also needed to form a tropical cyclone.
14
As air warms over the ocean,
15
it expands, becomes lighter and rises.
16
Other local winds blow in to replace the air that has risen,
17
then this air is also warmed and rises.
18
The rising air contains huge amounts of moisture evaporated from the ocean's surface.
19
As it rises, it cools,
20
condensing to form huge clouds about 10km up in the troposphere.
21
More warm air rushes in and rises,
22
drawn by the draft above.
23
The rising drafts of air carry moisture high into the atmosphere so that these clouds eventually become very thick and heavy.
24
Condensation then releases the latent heat energy stored in the water vapor,
25
providing the cyclone with more power.
26
This creates a self-sustaining heat cycle.
27
Drawn further upwards by the new release of energy,
28
the clouds can grow to 12 to 15 kilometers high.
29
The force created by the Earth's rotation on a tilted axis,
30
the Coriolis effect, causes rising currents of air to spiral around the centre of the tropical cyclone.
31
It is at this stage that the cyclone matures and the eye of the storm is created.
32
As the air rises and cools,
33
some of this dense air descends to form the clear,
34
still eye as the cyclone rages around it.
35
The eye wall, where the wind is strongest,
36
behaves like a whirling cylinder.
37
Cyclones rotate clockwise in the southern hemisphere, anti-clockwise in the northern.
38
The lowest air pressure in a tropical cyclone is always found at the centre,
39
and is typically 950 millibars or less.
40
The average air pressure at the Earth's surface is about 1,010 millibars.
41
Tropical cyclones have significantly lower air pressure than the air that surrounds them.
42
The bigger the pressure difference,
43
the stronger the wind force.
44
One of the lowest air pressures ever recorded was 877 millibars for Typhoon Ida,
45
which hit the Philippines in 1958,
46
where winds reached 300 kilometres an hour.
47
Once formed, the cyclone's movement or track follows a pathway away from its source,
48
driven by global wind circulation.
49
As warm ocean waters feed it heat and moisture,
50
the cyclone continues to enlarge.
51
Thank you.

背景與背景資訊
熱帶氣旋是一種極為複雜的氣象現象，它的形成過程及其生命週期對全球氣候有著深遠的影響。在此影片中，講解了熱帶氣旋的三個基本階段：起源階段、成熟階段和消散階段。瞭解這些過程不僅能夠幫助我們更好地理解自然界的現象，也為提升英語語言能力提供了豐富的學習材料。通過觀看該影片並進行英語影子跟讀，學習者可以在語音、語調和表達上取得顯著進步。
日常交流的五個重要短語
- 熱帶氣旋的形成 — "Formation of a tropical cyclone"
- 海洋表面溫度 — "surface temperature exceeds 26.5 degrees Celsius"
- 空氣上升和冷卻 — "air rises and cools"
- 風速加大 — "stronger wind force"
- 氣旋的中心 — "centre of the tropical cyclone"
逐步影子跟讀指南
對於想要提高英語發音並掌握氣象領域術語的學習者，以下是一個逐步的影子跟讀指南：
- 仔細觀看影片 — 首先，觀看影片內容，注意講解者的語速和語調，理解熱帶氣旋的形成過程。
- 選擇段落 — 選擇一個影片中的段落，最好是關於氣旋成熟階段的部分，因為這段內容較為詳細。
- 分段跟讀 — 將所選段落分成幾個小部分。先聽一遍，然後嘗試模仿講解者的發音和節奏，進行英語影子跟讀。
- 反覆練習 — 重複該段落多次，尤其是在聽到難以發音的部分時，集中練習以提高你的發聲能力。
- 記錄進步 — 可以錄下你的語音，與原聲進行對比，找出改進的地方，持續練習以提升你的英語發音。
通過這種影子跟讀的方法，不僅能增強你的語言能力，還能加深對氣象現象的理解，成為提高你的英語口語能力的有效途徑。加入這個練習，這是一項值得投資的語言學習技巧，幫助你在英語學習之旅中取得成功！
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
