谢谢你的提问，穆尔蒂！你的问题来得正是时候。
Powerful storms have been in the news recently, from a hurricane that hit the southern United States to a typhoon that blew into the Philippines, Vietnam and Thailand.
最近新闻报道有强劲风暴，从袭击美国南部的飓风到席卷菲律宾、越南和泰国的台风，。
Which word you might use to describe a storm often depends on where you are in the world.
用哪个词来描述风暴，往往取决于你位于世界的什么地方。
Let's start with hurricane.
我们先讲飓风吧。
Merriam-Webster Dictionary says that the word means a tropical cyclone with winds of 119 kilometers an hour or greater, and usually including rain, thunder, and lightning.
《韦伯词典》说，这个词的意思是风速每小时119公里或以上的热带气旋，通常带有雨、雷和闪电。
The term is used for such storms in the North Atlantic Ocean down to the Caribbean Sea.
这个术语用于描述大西洋北部至加勒比海的这类风暴。
Typhoons are the same kind of powerful ocean storm, or cyclone, but that term is used for storms in the Northwest Pacific Ocean.
台风是和飓风相同的强劲海洋风暴或者说气旋，但这个术语用于指太平洋西北部的风暴。
In the South Pacific and Indian Ocean, these storms are more commonly called tropical cyclones.
在南太平洋和印度洋，这些风暴通常被称为热带气旋。
All of these storms are considered cyclones because they rotate or move in a circular motion across tropical or subtropical warm waters.
所有这些风暴都被视为气旋，因为它们在热带或亚热带温暖水域旋转或者说作圆周运动。
You may have heard names like "tropical depression" or "tropical storm" in news coverage of hurricanes and the like.
你可能在有关飓风之类的新闻报道中听说过"热带低气压"或"热带风暴"的名称。
These kinds of storms can lead to a hurricane or typhoon depending on the speed of the winds.
根据风速的不同，这类风暴可能会导致飓风或台风。
A storm with winds below 62.7 kilometers per hour is a "tropical depression."
风速低于每小时62.7公里的风暴称为"热带低气压"。
If the winds are from 62.7 to 118 kilometers per hour, the storm is called a "tropical storm."
如果风速在每小时62.7到118公里之间，就被称为"热带风暴"。
And lastly, anything over 119 kilometers per hour is consider a hurricane, typhoon, or cyclone.
最后，任何超过每小时119公里的风暴都被认为是飓风、台风或气旋。
Hurricanes and typhoons include thunderstorms and storm surges from ocean water that can lead to coastal flooding.
飓风和台风带来雷暴和海水上升的风暴潮，可能导致沿海地区洪水泛滥。
Thunderstorms are heavy rainstorms in which you can hear thunder.
雷暴是可以听到雷声的暴雨。
During thunderstorms, winds are strong and there is always lightning.
在雷暴期间，风力强劲，总是伴随闪电。
You can find thunderstorms in different parts of the world, not just in the tropics.
在世界各地都可以看到雷暴，不是只有热带才有。
When thunderstorms become severe with intense winds, tornadoes can form.
当雷暴变得猛烈并伴有强风时，就会形成龙卷风。
Tornadoes are narrow storms that start in a thunderstorm and touch the ground.
龙卷风是一种小范围的风暴，从雷暴中形成并与地面接触。
They are very violent and destructive.
龙卷风非常暴力，且具有破坏性。
Here are a few examples of how we can use these words in sentences:
以下是使用这些词的几个例句：
Hurricane season in the Atlantic Ocean is from June through the end of November.
大西洋的飓风季节从6月持续到11月底。
Typhoon Noru quickly strengthened into a super typhoon last week with winds up to 175 kilometers per hour.
台风奥鹿上周迅速增强为超强台风，风速高达每小时175公里。
Often in the summer, thunderstorms form in the afternoons bringing heavy rain and lightning.
通常在夏天，雷暴会在下午形成，带来大雨和闪电。
Tornado Alley is an area in the central United States where tornadoes happen often.
龙卷风走廊是美国中部龙卷风频繁发生的地区。
