What and the 3 small scale atmospheric disturbance.
Thunderstorms
Tornadoes
Hailstorms
What are the 6 main hazards caused by tornadoes?
Heavy rainfall
Hail
High winds
Flying debris
Atmospheric pressure drop
Suction effect
How are tropical cyclones monitored?
Satellites
Aircraft reconnaissance
Radar
Ocean buoys.
What is a key tool used to predict the path of hurricanes?
Computer-based forecasting models that simulate storm tracks and intensities.
How do weather satellites help in prediction?
They provide real-time images and data on cloud formation, wind speed, and temperature.
What is an early warning system (EWS)?
A system that detects and forecasts hazards and communicates alerts to minimize risk.
What’s an example of a preparedness strategy for hurricanes?
Evacuation plans
Building code
Public education on emergency responses.
Why is community education important in preparedness?
It increases awareness and encourages proactive responses before disasters strike.
What is risk perception?
How individuals or communities view the likelihood and impact of a hazard.
What factors influence risk perception?
Past experiences
Education
Culture
Trust in authorities
Media coverage.
How does frequent exposure affect risk perception?
It can either desensitize people or increase vigilance, depending on outcomes.
Why might people live in high-risk areas despite known dangers?
Economic necessity
Cultural ties
Lack of alternatives
Underestimating risks
What role does media play in shaping risk perception?
It can amplify or downplay the severity of events, affecting public response.
What’s the relationship between risk perception and preparedness?
Higher perception of risk usually leads to better personal and community preparedness.
