How many levels of typhoons are there and how powerful they are
Typhoons, the giants of the tropical cyclone family, originate from low-pressure vortices over the oceans of the tropics or zones. It is powerful and far-reaching, and is revered as the king of the "tropical weather system".
In China, we pay special attention to tropical cyclones in the northwest Pacific Ocean, which are classified into six categories based on the magnitude of the maximum average wind (wind speed) near the center of their bottom layer. When the wind near its center is strong to force 12 or above, it is called a typhoon.
In the tropics, a powerful whirlpool is being born, and its center continues to emit violent winds. The wind speed is at 32 per second7 meters to 41Within 4 meters, it is like a herd of angry wild horses, galloping endlessly. This is a tropical cyclone, a force of nature that cannot be underestimated.
A tropical cyclone is upgraded to a severe typhoon when the winds intensify to reach a maximum wind force of 14 to 15 near its centre. The wind speed at this time is 41 per second5 to 509 meters, like a beast ready to attack, roaring to show the world its unrivaled strength.
And when the strength of the strong typhoon continues to gather and become a super typhoon, the wind speed will break through the 51 meters per second mark, reaching an astonishing speed of nearly 300 kilometers per hour, and the typhoon will not be lower than 16 at this time. Almost no one can compete with such a wind, and everywhere it goes, it leaves traces of destruction. It is powerful enough to flatten buildings on land and send waves of more than 14 meters into the ocean.
The ability of the aircraft carrier to resist wind and waves
The aircraft carrier has three levels of wind and wave resistance, the first is the lowest level, which can resist typhoons of magnitude 8-9 and the wind speed is about 172～24.4 meters and seconds, this kind of aircraft carrier existed in World War II and before, and has been decommissioned, and there is no such aircraft carrier.
The second is a medium-class anti-wind and wave aircraft carrier: it is expected to be able to resist 10-11 typhoons, with a wind speed of about 245～32.6 meters and seconds, which is the minimum standard for most modern aircraft carrier designs, generally corresponds to modern small aircraft carriers, and the displacement is generally less than 30,000 tons.
The third type of high-level anti-wind and wave aircraft carrier: can resist the speed of up to 51 meters per second to the first wind, generally refers to 14-15 typhoons, which is the highest level, the current medium-sized aircraft carriers can basically reach this level, this kind of aircraft carrier displacement generally exceeds 30,000 tons.
Regarding typhoons with a magnitude of 16 or higher, the wind speed is staggering. The wind speed broke through the 51-meter mark, approaching a speed of more than 300 kilometers per hour. When such a typhoon hits, it leaves a deep mark of destruction wherever it passes. Even the most advanced aircraft carrier in the world at present is powerless and difficult to resist in the face of such a typhoon.
Thankfully, however, such typhoons of magnition 16 and above are extremely rare and almost impossible. Therefore, for countries with large nuclear-powered aircraft carriers with a displacement of more than 120,000 tons, they do not need to worry too much about the threat of such extreme weather. At the moment, only the United States has such an aircraft carrier.
