    Cards (77)

    • What is a typhoon?
      A severe weather disturbance with strong winds
    • Where does a typhoon typically form?
      In the northwestern Pacific Ocean
    • What is the wind speed of a tropical depression?
      Up to 62 kph
    • What wind speed defines a tropical storm?
      63-118 kph
    • What is the wind speed of a typhoon?
      Greater than 118 kph
    • What is a super typhoon?
      A typhoon with wind speed exceeding 220 kph
    • What does the term "typhoon" derive from?
      The Chinese term "Tai Fung"
    • What does "ta" and "fung" mean in Chinese?
      "Ta" means big and "fung" means wind
    • What is the local term for typhoon in the Philippines?
      Bagyo
    • What significant event occurred in Baguio City in 1911?
      A tropical cyclone dropped 2200 mm of rainfall
    • What are tropical cyclones characterized by?
      Rapid rotation and formation over tropical oceans
    • What is the second-most dangerous natural hazard?
      Tropical cyclones
    • What is the eye of a cyclone?
      The calm center with light winds and clear skies
    • What is the diameter of the eye of a cyclone?
      30-50 km
    • What is the eyewall of a cyclone?
      The most intense part with strongest winds
    • What do rainbands do in a cyclone?
      Bring heavy rain and strong winds
    • How does a tropical cyclone form?
      Warm ocean water heats air, causing it to rise
    • What role does the Coriolis effect play in cyclones?
      It causes the system to spin
    • What are the damages caused by typhoons?
      Building damage, floods, and economic disruption
    • What positive effects do typhoons have?
      Replenish groundwater and support flora
    • What is indicated by a rapid drop in atmospheric pressure?
      Rising air leading to storms and rain
    • What does heavy rainfall signal?
      The approach of a typhoon
    • What happens to sea levels during a typhoon?
      They rise due to storm surges
    • What is the "eye of the storm"?
      A brief period of calm during a typhoon
    • What measures can mitigate typhoon effects?
      Identifying high-risk areas and regulations
    • Why are strict land use regulations important?
      To ensure structures withstand typhoons
    • What is the benefit of effective forecasting?
      Provides early warnings for evacuations
    • What is a storm surge?
      An abnormal rise in sea level during storms
    • What causes storm surges?
      Strong winds and low atmospheric pressure
    • How does storm intensity affect storm surges?
      Stronger winds create higher storm surges
    • What is the pressure effect on storm surges?
      Low pressure reduces weight on ocean surface
    • How does the size of a storm influence storm surges?
      Larger storms push more water toward coast
    • What is the effect of storm forward speed on surges?
      Faster storms cause rapid surges
    • How does the angle of approach affect storm surges?
      Direct hits create higher surges than parallel
    • What is the Coriolis effect's influence on storm surges?
      It affects surge strength based on storm path
    • How does rainfall affect storm surges?
      It worsens flooding by increasing runoff
    • What coastal geometry amplifies storm surges?
      Shallow, concave, or funnel-shaped coastlines
    • How does timing affect storm surge impact?
      High tide increases flooding from surges
    • What is the purpose of prediction and hazard mapping?
      To predict storm surges and aid planning
    • What are barriers in storm surge management?
      Structures that prevent inland flooding
