By reading the following steps, readers will be able to understand how a typhoon forms and increase their awareness of the dangers of typhoons thereby reducing the risks of being damaged by consequences caused by typhoons. First of all, a large quantity of water evaporates from tropical seas into the air, which is caused by the long hours of sunlight during summer and will lead to strong cumulonimbus clouds. After a few hours, a tropical depression, the initial stage of a typhoon forms. 英语论文代做
The hot air in the cumulonimbus clouds rises and the cold air around rushes in, and forms a tropical cyclone with little air at its centre. As this process repeats, the tropical depression continues to strengthen. Because the central pressure is lower that the outside area. The surrounding air keeps rushing in to the low pressure centre. This heats the air and it rises, providing more energy, which makes the central pressure drop further. After the maximum wind speed near the center reaches a certain standard. The tropical depression increases to a tropical storm, then to a typhoon or a super typhoon, which depends on the energy input and energy output proportion.
If the input energy is greater than the output energy, the typhoon will strengthen. 英语论文代做
Finally, the typhoon makes landfall in coastal cities and it may be powerful enough to causes serious disasters. The heavy rain and winds of a typhoon could destroy houses and cars and people should be aware of the dangers of typhoons and the importance of preparing for a typhoon before it comes
Typhoons are often powerful and they usually cause enormous damage to people’s property and threaten people’s lives. But by analysing how typhoons form we may know what to do when they occur and be safe. Firstly, a tropical cyclone appears over a warm expanse of ocean. When the temperature of the sea reaches over 80oF and its expanse is of a certain degree, a tropical cyclone would gradually form. Then, the
strong wind pulls in moisture from the ocean, allowing the tropical cyclone to grow. 英语论文代做
Next, the tropical cyclone converts the moisture into heat. And the heat causes more air to flow to the centre of the storm, causing evaporation. After that, a rough weather wave strikes, using the earth’s rotation, the storm begins to rotate. Finally all the heat and air flows toward the eye of the tropical cyclone, creating a typhoon. Researches show that a link between global warming and the increasing number of typhoons exist. Because global warming causes the global temperatures to rise and it creates an environment for typhoons to form. Be alert that when typhoons occur, they usually come along with extremely strong winds, so stay indoors and stand away from windows. All in all, typhoons are mighty and destructive; therefore, we should take action and do our best to slow the process of global warming, and more importantly we should be prepared for typhoons. 英语论文代做
