From Monster to Typhoon: The Science of Weakening
Why Ragasa lost strength before landfall

Key Science Points

  • Dry Air Intrusion: Cooler, drier air cut off Ragasa’s supply of tropical moisture.
  • Land Interaction: Friction with terrain disrupted the storm’s circulation.
  • Coastal Waters: The relatively cooler waters near Guangdong reduced available heat energy.

    Climate Connection

    While Ragasa weakened before landfall, the fact that it reached Category 5 strength in the first place speaks to a broader trend: warming oceans are fueling stronger storms. Climate change is amplifying rainfall intensity, storm surges, and wind damage across the Pacific basin.

    Explaining these processes helps demystify why typhoons can shift so quickly. Residents and policymakers alike benefit from understanding how weather systems evolve, so they can prepare better and respond faster.
