Duration of Guangdong's Typhoon Season
For residents of Guangdong, typhoons are not just "visitors" in a specific month but rather "regulars" that may stay from early summer to late autumn. Generally, the active typhoon period in Guangdong is concentrated between May and November. Among these, July, August, and September represent the "peak season" for typhoon landfalls or impacts. During these three months, typhoons are frequent, intense, and follow complex paths, requiring heightened vigilance.
Although typhoons are relatively less common in May and June, these months are not entirely safe; occasional early-season typhoons can form and bring heavy rainfall. By October and even November, while the frequency decreases, the combined influence of cold air and the outer circulation of typhoons often leads to "autumn typhoons." These systems tend to produce prolonged rainfall, easily triggering secondary disasters. Therefore, from a meteorological statistical perspective, it is more scientific to maintain psychological preparedness for typhoons throughout the entire summer and autumn seasons.
Average Annual Typhoon Count and Impact Characteristics
Regarding the question "how many typhoons typically occur per year," we need to distinguish between the number of typhoons "formed" and those that "impact" the region. In the Northwest Pacific and the South China Sea, an average of about 25 typhoons form annually, but this does not mean they all affect Guangdong.
Specifically for Guangdong, an average of 3 to 4 typhoons make direct landfall or severely impact the province each year. It is important to note that this figure is a multi-year average, and actual annual variations can be significant: some years may be relatively calm with only 1-2 typhoons grazing the area, while active years may see 6-7 or even more typhoons striking in succession. Furthermore, even if a typhoon does not make direct landfall, its extensive outer cloud bands can still bring strong winds and heavy rain to Guangdong. Therefore, "landfall" should not be the sole criterion for assessing risk.
Scientific Defense and Warning Response
When facing typhoons, a scientific response is more important than blind panic. According to the national standards for tropical cyclone grades issued by the China Meteorological Administration (CMA), typhoons 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. The public should closely monitor warning signals issued by meteorological authorities.
When a typhoon warning is issued, please pay attention to the following points:
- Monitor Official Information: Regulations regarding school suspensions, work stoppages, and business closures corresponding to yellow, orange, and red typhoon warnings may vary by location. Local standards may differ; please refer to announcements from local governments.
- Clear High-Altitude Hazards: Check items on balconies, such as flower pots and outdoor air conditioning units, that could fall, and reinforce windows and doors.
- Stockpile Emergency Supplies: Prepare adequate drinking water, food, flashlights, and common medications to prepare for potential water and power outages.
- Avoid Going Out: During the impact of a typhoon, minimize non-essential outings and stay away from billboards, large trees, and temporary structures.
The key to disaster prevention lies in being "early" and "detailed." Maintaining sensitivity to weather changes is essential to maximizing the protection of life and property. Real-time typhoon tracks can be queried at TyphoonSays (taifengshuo.com)
