How did the Typhoon form?

Typhoon is not generated by air, it is essentially a strong cyclone formed on a tropical ocean.To understand its formation, we can imagine it as a huge "heat engine" that requires specific fuel and launch conditions to operate.
Typhoon’s “birth crust”: four essential conditions
Typhoon formation is extremely challenging and must meet the following four critical conditions at the same time:
- Extensive high temperatures.Typhoon: This is the source of energy typhoon. usually requires sea surface water temperature above 26.5 ° C, and warm water layer to be sufficient depth (generally more than 50-60 meters) . high-temperature sea water evaporates a lot, providing sufficient water vapor and subheat to the atmosphere, like injecting high-standard fuel to the engine.
- Initial disruption of air flow.Over the ocean there needs to be a weak low-pressure turbine or air flow disturbance.It is like the flash of the ignition engine, letting the air start to rotate and gather.Without this initial disturbance, even if the sea water warms again, the air will only rise vertically, and can not form a rotational storm system.
- Strong enough toward.The choriolithic force produced by the Earth's rotation is key to allowing the airflow to rotate. thus, Typhoon is usually formed in places at least 5 latitudes away from the equator. On the equator, the toward force from at the earth is almost zero, and the airflow cannot rotate effectively, so the Typhoon is rarely formed near the equator.
- Vertical winds are smaller.Referring to the high and low wind speed, the difference in wind direction can not be too big.If the upper and lower wind speed difference is too big, the newly formed heating structure will be "blown off", leading to the typhoon embryo shattering.
From Nameless to Super Typhoon
When the above conditions are met, the humid hot air on the tropical ocean surface is heated up, the surrounding cold air is supplemented, and under the action of the ground turn toward force begins to turn the clock (N hemisphere) . . as the hydrophobic condensation releases a huge amount of heat, the Pressure is lower and lower, the inhaled air is more and more, the speed of rotation is faster and faster, and eventually forms Typhoon .
According to the National Standard of Tropical Cyclones issued by the China Meteorological Administration, we divide tropical cyclones into six levels based on the maximum average wind speed near the bottom center: Nameless, Tropical Storm, Severe Tropical Storm, Typhoon, Severe Typhoon and Super Typhoon.
Scientific Defense, Safety First
Understanding Typhoon formation mechanisms can help at We better respect nature.When the meteorological department releases a Typhoon early warning signal, it means that the effects of the storm are about to or have arrived.It should be noted that interruptions, shutdowns, and shutdowns may vary by local governments.Be sure to check the window reinforcements before Typhoon arrives, clean out balcony debris, reserve the necessary food and drinking water, and watch the latest weather forecast information closely, to avoid going out during bad weather.
