Typhoon

What is Typhoon?

Tropical cyclones are known by various names in different parts of the world.
- In the North Atlantic Ocean and the eastern North Pacific, they are called hurricanes
- In the western North Pacific around the Philippines, Japan, and China the storms are referred to as typhoons.
- In the western South Pacific and Indian Ocean they are variously referred to as severe tropical cyclones, tropical cyclones, or simply cyclones.
All these different names refer to the same type of storm.

Pre-conditions

Typhoons is just another term for hurricane, so they share the same conditions
When seven atmospheric conditions come together, it causes typhoon to form
Pre-existing disturbance, warm ocean water, low atmospheric stability, sufficient coriolis force, moist mid-atmosphere, upper atmosphere divergence are the seven factors
Typhoon is a large heat engine, therefore the factors are important in that heat energy is delivered to the higher latitudes
It occurs as water vapor evaporates from the ocean into the clouds.

Effects: typhoons majorly affects to humans, animals, and plants

Humans: People can be killed, injured, or lost during typhoons because of flooding and strong winds. Serious flooding causes people to drown and destroy houses and crops that results in a food shortage. Moreover, there will be less access to medical care and medical supplies. Sometimes, access to major roads could be limited if there are damages from a typhoon.

Animals: Flooding is mostly caused by typhoons which will drown animals and destroy natural environments. Smaller animals are most likely to get killed due to their weaknesses. Food chains will collapse and larger animals will no longer have enough food to find. Finally, animals that rely on humans will possibly get killed because they will lose the man-made shelters and human caretakers will be unable to help them because they have also been affected by a typhoon.

Plants: Since plants are the weakest from three factors, their life can be easily killed by floods and strong winds. Even trees may not hold on to the force of a typhoon’s strength. Heavy rains will drown plants, and also cause soil erosion. Mudslides often rip the root of plants leading it to get killed.

Solution

There is no prevention of forming cyclones or exact warning signals in force.

Therefore, precise forecasting and preparation to reduce damage are essential.

An international team of researchers (Mingkui Li, associate professor in the Key Laboratory of Physical Oceanography in the Ocean University of China and the Pilot National Laboratory for Marine Science and Technology (QNLM). ) has developed a model that analyzes nearly a quarter of Earth's surface and atmosphere in order to better predict the conditions that birth typhoons, as well as the conditions that lead to more severe storms.

the onset time, central pressure and maximum wind speed."

With those three variabilities in mind, the researchers coupled prediction models of the atmosphere and the Earth's surface covering Asia and the Pacific Ocean. They examined three coupled models, each accounting for a different area depth. The researchers also accounted for the influence of one variable on another, such as wind speed on sea surface temperature, a phenomenon known as coupled data assimilation

Despite these efforts, there is still a lack of technology to predict everything about typhoon. However, through this study, it is possible to predict the approximate path, intensity, and duration of the typhoon with a high probability.
