热带风暴与飓风
The difference between tropical storm and hurricane is in the wind speed of the storm. The areas along the coastline that are affected by frequent storms and weather disturbances know the kind of destruction of property and loss of lives that these natural calamities bring in their wake. People in U.S. have still not forgotten the devastation that was caused by Katrina in 2005. It was the deadliest hurricane to have struck the coast of the country in the last 100 years. More recently, hurricane Dolly caused havoc in the country, in 2008. This is why it is prudent for people to know the differences between a tropical storm and a hurricane.
When there is a low pressure centre along with thunderstorms, it is usually referred to as a tropicalcyclone。当从海洋水中水时,这些旋风会获得强度evaporates and condenses以水蒸气的形式。热带单词的使用是因为这些旋风在特别地理区域的起源,而这些风暴之所以称为旋风的原因是由于逆时针方向的风流,在北半球,同时是顺时针方向,南半球。在不同的名称中,热带气旋根据其位置及其强度或强度提及。更常见的名字是飓风,热带抑郁症,台风,旋风和旋风风暴。
热带气旋有三组,当它们处于起步阶段时,它们被称为热带凹陷。当他们的强度增加时,它们就会成为热带风暴。第三个分组包括非常高强度的热带气旋,当它们在大西洋发生时,当它们在西北太平洋地区时被称为飓风时,它们被称为飓风。令人惊讶的是,当这些热带气旋到达印度洋时,它们既不是飓风,也不是台风,而是旋风。
Thus, the first stage of a potentially devastating hurricane is that of a tropical depression. We get a low pressure area in the ocean with wind speeds less than 39 mph, or between 23 and 39 mph.
什么是热带风暴?
If the storm that begins as a tropical depression gets more organized and the speeds of the winds become greater than 39 mph, the cyclone is called a tropical storm. During the initial stage of the tropical cyclone, which is the tropical depression, the storm does not receive a name like Katrina or so. At this initial stage, it is simply known as Tropical Depression 05 or something similar that is not very noteworthy. However, once this Tropical Depression 05 gains a wind speed of more than 39 mph, it officially becomes a tropical storm. Now, the National Hurricane Centre gives it a name because it is becoming a significant event. Even after the same tropical storm changes into a hurricane, the name given to it such as Katrina or Bobby is still used.
What is a Hurricane?
The hurricane is the third stage a tropical cyclone can reach. It is only when the wind speeds inside the centre of the storm become greater than 73 mph that the storm gets categorized as a hurricane. There is a scale called Saffer-Simpson scale that tells us the category of a hurricane. Thewind that speeds between 74 and 95 mph qualifies a hurricane as category 1, and these are harmless hurricanes. It is when the风速接触111英里 /小时,飓风到达被称为主要飓风的阶段。The last and final stage that classifies hurricanes as5级时发生的速度经过155年mph。
What is the difference between Tropical Storm and Hurricane?
热带风暴和飓风之间的基本区别在于旋风的强度。
•热带风暴和飓风的定义:
•如果旋风的风速大于39 mph,则称为热带风暴。
• When the wind speeds become greater than 73 mph, the same cyclone becomes a hurricane (or a typhoon).
• When the wind speed remains below 38 mph, the cyclone is referred to as a tropical depression only.
• Connection:
• Tropical storm and hurricane are the second and third stages a tropical cyclone can reach respectively.
• Hurricane Categories:
•速度在74至95 mph之间的风能将飓风视为1类。
• Category 2 hurricanes have a wind speed from 96–110 mph.
• Category 3 hurricanes have a wind speed from 111–129 mph.
• Category 4 hurricanes have a wind speed from 130–156 mph.
• Category 5 hurricanes have a wind speed that is more or equal to 157 mph.
