Questions
What is the minimum sea surface temperature generally needed for a tropical storm to form?
About 15°C
About 20°C
About 26.5°C
About 32°C
20s
Which description best fits the eye of a mature tropical storm?
Rapidly rising air forming towering clouds
Strongest winds and the heaviest rainfall
Calm conditions, sinking air and largely clear skies
Spiralling rain bands with gusty squalls
20s
On what is a hurricane's category on the Saffir–Simpson scale based?
Height of the storm surge
Maximum sustained wind speed
Central air pressure
Total rainfall over land
20s
Why do tropical storms rarely form within about 5° of the equator?
The Coriolis effect is too weak to start rotation
Wind shear is always too strong there
Air pressure is too low there
Sea temperatures are too low there
30s
Typhoon Haiyan (2013) was called a typhoon because it formed in which ocean basin?
North Atlantic
Northern Indian Ocean
South-west Indian Ocean
North-west Pacific
20s
Which combination of factors mainly causes a storm surge?
High air pressure and offshore winds
Heavy rainfall and swollen rivers
Low air pressure and strong onshore winds
An undersea earthquake and landslide
30s
Why does strong vertical wind shear prevent a tropical storm from developing?
It reverses the direction of the Coriolis effect
It tilts and tears apart the storm's vertical structure
It cools the sea surface below 26.5°C
It raises air pressure at the storm's centre
30s
In Hurricane Katrina (2005), what was the main cause of about 80% of New Orleans being flooded?
Storm surge overtopping and breaching the levees
Snowmelt raising Lake Pontchartrain upstream
A tsunami travelling across the Gulf of Mexico
Rainfall making the Mississippi burst its banks
30s

Recovery
Preparedness
Response
Mitigation
