Most hurricanes form in what latitudes
Give this one a try later!
8 - 20 degree latitudes
tropical depression stage
Give this one a try later!
tropical low
- surface winds 20 - 34 knots
- rotating!
,Enhanced Fujita Scale
Give this one a try later!
Tornado scale used since 2007
0 = 65 - 85 mph (light)
1 = 86 - 110 mph (moderate)
2 = 111 - 135 mph (considerable)
3 = 136 - 165 mph (extreme)
4 = 166 - 200 mph (devastating)
5 = > 200 mph (incredible)
How is horizontal vorticity created?
Give this one a try later!
created by wind shear in atmospheric boundary layer
What are the isobars like in a hurricane?
Give this one a try later!
air pressure is distributed symmetrically about the L
- isobars are closely spaced and concentric circles
What does cyclostrophic balance do?
Give this one a try later!
, minimizes radial inflow and maintains low pressure centre
Tornados threaten people and property 4 ways
Give this one a try later!
1. extremely high winds
2. a strong updraft
3. subsidiary vortices
4. abrupt drop in air pressure
Rotation in a fluid is measured by what
Give this one a try later!
vorticity
How are time and frequency related?
Give this one a try later!
F = 1/T
or T = 1/F
