Science 8 Quiz #4 2nd Quarter

What factor is crucial for accurate track prediction of a typhoon?

• Temperature fluctuations
• Migration of high- and low-pressure areas
• Wind shear patterns
• Sea surface temperature

Why is it important for PAGASA to predict the pathway of a typhoon accurately?

• To prevent rainfall and tornadoes
• To minimize the effects of storm surges and destruction
• To control the wind speeds of the typhoon
• To measure the height of waves

How often is the path of a typhoon predicted and updated during its progress?

• Every 12 to 24 hours
• Every 6 to 12 hours
• Every 1 to 3 hours
• Every 2 to 4 hours

Which part of the typhoon is characterized by calm weather despite the surrounding destructive forces?

• Eyewall
• Rain bands
• Eye
• Spiral inflow

What do PAGASA’s meteorological tools focus on when forecasting the strength and track of a typhoon?

• Rainfall amounts
• Temperature gradient
• Wind direction only
• Pressure systems

What was a major factor that contributed to the devastating impact of Super Typhoon Yolanda in 2013?

• Sudden shift in the storm’s path
• Inaccurate weather forecasts
• Lack of public heed to precautionary warnings
• Lack of computer forecast models

Which of the following meteorological signs does NOT indicate an approaching typhoon?

• Increasing wave height
• Heavy rainfall
• Falling air pressure
• Rising air pressure

What would be the consequence of an incorrect typhoon track forecast?

• Incorrect storm surge and rainfall predictions
• Reduced typhoon speed
• Accurate tornado threat assessments
• Slower computer modeling results

What makes the wind speed at the eyewall particularly dangerous?

• The wind speeds are calm but sporadic
• The winds blow in alternating directions
• The winds are calm but carry heavy rainfall
• The winds are fast and concentrated near the dense clouds

When the eye of a typhoon passes over a location, what typically happens to the weather conditions?

• Winds speed up significantly
• Calm weather takes over briefly
• Torrential rain begins
• Tornadoes are likely to form
