Measurement And Predictability Flashcards
What kind of scale is the Saffir Simpson scale?
Absolute
What are the limiting factors of the Saffir Simpson scale?
- Doesn’t take rainfall into account (flooding)
- Doesn’t take geography into account (New Orleans)
- Doesn’t take population density/urbanisation into account
What’s it called when we predict hurricanes/disasters based on past events?
Hurricane/disaster return period
- Can help predict travel paths
Is it proven that climate change is directly impacting tropical storms?
No - but the evidence of rising sea temperatures suggested it. Eustatic sea level rise may increase stor surge impact. Scientists need a longer assessment period to confirm.
How could negative feedback counteract climate change impacts on tropical storms?
Increased wind sheer could counteract more moisture in the air
What does the NOAA do to aid prediction?
Publishes annual prediction of hurricane activity.
Uses sea-surface temps, atmospheric conditions and climate cycles.
What are the limitations of the NOAA?
Does not predict likely landfall (can’t help early warnings).
Does not work on a local scale.
