What's the difference between tornado, typhoon, gust, hurricane and whirlwind?

Hurricanes: Strong and deep tropical cyclones in the Atlantic Ocean and the North Pacific Ocean (maximum wind speed is 32.7m/s, and the wind is above 12) are called hurricanes, and also refer to strong winds, any tropical cyclones and any strong winds with wind 12. There is an eye in the center of the hurricane. The smaller the eyes, the greater the destructive power. Its significance is similar to that of a typhoon, but it is produced in different places.

Typhoon: refers to a tropical cyclone formed on the vast sea surface above 26℃ in tropical or subtropical areas. The western part of the North Pacific (north of the equator, west of international date line, east of east longitude 100 degrees) is usually called a typhoon, while the North Atlantic and the East Pacific are generally called hurricanes. Every summer and autumn, there are many violent storms called typhoons in the Pacific Northwest adjacent to China. Some dissipate at sea, while others land on land, bringing storms, which is a natural disaster.

Tornado: It is the strongest vortex phenomenon in the atmosphere. It is a strong wind vortex with small range and strong wind force extending from the bottom of thunderstorm cloud to the ground or water surface. Summer often occurs in thunderstorm weather, especially in the afternoon to evening. Although the scope of influence is small, it is extremely destructive. Cyclone: It is a kind of rotating air vortex, which flies into the air with dust carried by the ground. This vortex is what we usually see, and it is a natural phenomenon caused by air flow. Less destructive and less common.

Gust is the result of air disturbance. When the fluid flows over the moving solid surface, it will encounter the resistance of the solid surface, which will slow down the fluid flow rate. Air is a fluid. When the air flows through the ground, due to the resistance of the ground to the air, the wind speed in the lower layer decreases and the upper layer remains unchanged, so that the air is disturbed. It not only goes forward, but also goes down. When the wind is strong, meteorological stations often add "gust" to the wind forecast, such as wind level 5-6, gust level 7, or wind level 7-8, gust level 9. It means that the general (or average) wind force is 5-6 (or 7-8), and the maximum wind force can reach 7 (or 9), and the gust can reach its maximum in a short time or in an instant.
