Super Typhoon Ragasa makes landfall in China | BBC News

Super Typhoon Ragasa Update: Approaching Chinese Mainland

Key Concepts:

• Super Typhoon Ragasa (downgraded to severe storm)
• Guangdong Coast, China
• Hong Kong Typhoon Warning System (Level 8)
• Storm Surge (up to 5 meters)
• El Niño-Southern Oscillation (ENSO) - La Niña
• Climate Change Impact on Typhoon Intensity and Rainfall
• Evacuation and Relocation Efforts

Current Status and Impact

• Ragasa's Strength: Initially a Category 5 equivalent, Ragasa has been downgraded from a super typhoon to a severe storm.
• Location: Approximately 200 kilometers west of Hong Kong.
• Wind Speed: Maximum wind speeds around 105 kilometers per hour.
• Minimum Pressure: 948 millibars.
• Hong Kong Impact:
  • Typhoon warning at level 8 (downgraded from 10).
  • Hundreds of flights grounded.
  • Schools and businesses shut down.
  • 50 temporary shelters operating.
  • Over 400 fallen tree reports.
  • Reports of landslides and 15 floodings.
  • Over 60 people receiving treatment in emergencies.
  • Escalated rainfall expected, especially in the northern part.
  • Storm surge expected to heighten.
• Taiwan Impact: 15 fatalities due to a lake bursting its banks. 17 people still missing.
• Macau Impact: Streets are empty due to the storm. Significant rainfall.
• Storm Surge Danger: Expected storm surges of up to 5 meters, posing a significant threat, especially when combined with high tides. An expert noted the dangerous combination of storm surge and high tides.

Expert Perspective: Professor Jung Unu (City University of Hong Kong)

• Increased Typhoon Frequency: Hong Kong typically experiences around six typhoons per year, but Ragasa is already the ninth.
• El Niño-Southern Oscillation (ENSO): The increased typhoon frequency is linked to the La Niña phase, which causes relatively warmer waters in the western Pacific, leading to more tropical cyclones in areas like South China.
• Climate Change Influence: Climate change is influencing the intensity and rainfall associated with typhoons. Western Pacific and South China are experiencing a higher number of intense storms.
• Future Trajectory: Ragasa is expected to make landfall in South China within a few hours and gradually weaken.
• Storm Surge Timing: The impact of storm surge will be more dangerous if it coincides with high tide, which typically occurs around 9:00 PM and 9:00 AM in Hong Kong and southern China.

China Mainland Impact and Response

• Evacuation: Nearly 2 million people have been relocated across China. More than a million people have been relocated to safe ground.
• Guangdong Province: The storm is approaching the Guangdong coast.
• Wind Speed Expectations: Winds of up to 120 kilometers per hour are expected.
• Evacuation Measures: Buildings above 10 floors have been evacuated. Residents are taping windows and using sandbags to protect against coastal and tidal surges.
• Authorities' Advice: People are urged to stay indoors.
• Economic Impact: 11 major Chinese cities are at a standstill, including parts of Shenzhen (technology hub) and Guangdong (manufacturing hub). Some factories are restarting operations as soon as the typhoon subsides, while others have halted production to ensure worker safety.

Synthesis/Conclusion

Super Typhoon Ragasa, while downgraded to a severe storm, continues to pose a significant threat to the Chinese mainland, particularly the Guangdong coast. The combination of strong winds, heavy rainfall, and dangerous storm surges, especially when coinciding with high tides, necessitates ongoing vigilance and preparedness. The increased frequency of typhoons in the region is linked to the La Niña phenomenon, exacerbated by the long-term effects of climate change on storm intensity and rainfall. Extensive evacuation efforts are underway to minimize casualties and damage, but the economic impact on major manufacturing and technology hubs is considerable.
