Typhoons Can Still Occur in November
Many people mistakenly believe that typhoons completely "disappear" as autumn and winter approach. This is a misconception. Although November is considered late autumn or early winter, sea surface temperatures in the Northwest Pacific and the South China Sea often remain above 26°C, providing the thermal conditions necessary for tropical cyclone formation. Therefore, typhoons do occur in November; historically, there have even been severe typhoons making landfall along the southern coast of China. However, compared to the peak summer season, the frequency of typhoon formation in November drops significantly. It is considered the "tail end" of typhoon activity, but one should never let their guard down.
The Unique "Temperament" of Late-Season Typhoons
Compared to summer typhoons, November typhoons have distinct characteristics, primarily reflected in their track complexity and intensity changes:
- Unpredictable Tracks: At this time, the subtropical high retreats southward and weakens, making steering flows unstable. Coupled with frequent cold air activities, typhoons are easily influenced by various weather systems such as cold highs and westerly troughs. This can lead to sudden turns, stagnation, or looping paths, making forecasting particularly challenging.
- "Autumn Typhoons" Can Be Stronger: Meteorological statistics show that once late-season typhoons form, they are more likely to develop into severe typhoons or super typhoons. This is because the ocean has accumulated significant heat during the autumn, and the upper-level atmospheric environment is sometimes more conducive to maintaining the typhoon's core structure.
- Compounded Wind and Rain Impacts: If a typhoon moves north and encounters southward-moving cold air, it can trigger more intense precipitation than a typhoon alone, creating a situation of "heavy wind and rain." The risk of disaster in such scenarios should not be underestimated.
Key Defense Points and Response Recommendations
In the face of potential typhoons in November, residents should focus on the following points:
- Beware of Compounded Wind and Rain Effects: Late-season typhoons are often accompanied by cold air, leading to simultaneous sharp temperature drops, strong winds, and heavy rainfall. The perceived temperature can be extremely low. In addition to protecting against wind and rain, it is important to stay warm to prevent colds and cardiovascular diseases.
- Monitor Warning Signals: Please closely monitor typhoon warning signals issued by local meteorological departments. According to the standards of the CMA (China Meteorological Administration), typhoon warnings are divided into four levels: Blue, Yellow, Orange, and Red. The higher the level, the greater the hazard. When high-level warnings are issued, measures such as school closures, work suspensions, and transport halts may be implemented. Specific execution standards may vary by location, so please refer to announcements from local governments.
- Clear High-Altitude Hazards: Autumn is dry and windy, making it easy for strong winds to blow down billboards, flower pots, and other objects from heights. It is advisable to check that windows and doors are securely closed and to clear items hanging on balconies to avoid injuries from falling objects.
Although the number of typhoons decreases in November, their suddenness and destructive power should not be underestimated. Staying alert and preparing supplies and emergency plans are key to dealing with late-season typhoons. Real-time typhoon tracks can be checked at TyphoonSays (taifengshuo.com)
