What is the Difference Between Typhoons, Hurricanes, and Cyclones?

Same Essence, Different Names
Many people feel confused when they hear terms like typhoon, hurricane, or cyclone. In meteorology, however, they refer to the same weather system, collectively known as "tropical cyclones." This is similar to how potatoes are called different names in different regions; the main difference lies in their place of origin.
According to the World Meteorological Organization, tropical cyclones occurring in the Northwest Pacific and the South China Sea are called typhoons; those occurring in the Atlantic, the Northeast Pacific, and parts of the Indian Ocean are called hurricanes or cyclones. Although the names vary, their formation mechanisms are identical: all originate from intense air vortices over tropical oceans, accompanied by strong winds, heavy rain, and storm surges. For residents along China's coast, we primarily face typhoons, so daily disaster prevention efforts should focus on understanding and responding to typhoons.
Intensity Levels and Warning Signals
Understanding typhoon intensity helps us assess risk levels. According to the national standard "Tropical Cyclone Grades" issued by the CMA (China Meteorological Administration), tropical cyclones are classified into six levels based on the maximum wind force near the center: tropical depression, tropical storm, severe tropical storm, typhoon, severe typhoon, and super typhoon. Among these, "typhoon" and higher levels usually indicate significant destructive power.
When meteorological departments issue warning signals, the public must pay close attention. Taking common typhoon warnings as an example, the danger level increases progressively from blue to red.
- Blue/Yellow Warning: Indicates that a typhoon may affect the local area. Prepare for wind protection and check windows, doors, and outdoor items.
- Orange/Red Warning: Means the typhoon will bring severe wind and rain impacts. Avoid going outdoors, and residents in dangerous areas must cooperate with evacuation orders.
It is particularly important to note that specific regulations regarding school suspensions, work stoppages, and transport halts may vary by location and are subject to local government announcements. For instance, some cities mandate school closures for primary and secondary schools upon the issuance of a yellow typhoon warning, while other regions may only implement comprehensive work and school suspensions when orange or red warnings are issued. Please keep an eye on the latest notifications from local education bureaus and emergency management departments, and do not rely solely on past experience.
Scientific Defense, Safety First
Regardless of the name, scientific defensive measures are key to protecting life and property against such extreme weather. Before a typhoon arrives, residents are advised to make the following preparations:
- Clear Balconies: Move easily falling items such as flower pots and clothes hangers indoors to prevent injuries from falling objects.
- Stockpile Supplies: Prepare adequate drinking water, ready-to-eat food, flashlights, and common medicines in case of water and power outages.
- Reinforce Windows and Doors: Check if glass is secure; if necessary, apply tape in a "rice" character pattern to increase resilience.
During the typhoon's impact, the safest action is to stay indoors in a sturdy area, away from windows. If you are outdoors, seek shelter in a safe building immediately; do not linger under billboards, large trees, or temporary structures. If encountering flooding or waterlogging, do not wade through water blindly, and be wary of missing manhole covers or the risk of electric shock. Disaster prevention and reduction are not only the government's responsibility but also require the active participation and correct response of every resident.
