|
|
5 parameters for a cyclone to occur
|
1.pre-existing tropical disturbance
2. sea surface temperature of >79 3. favorable coriolis 4. divergence aloft 5. minimal.low vertical windshear |
|
tropical depression
|
tropical cyclone with wind speed of 33kt or less

hurrican/typhoon
|
tropical cyclone with wind speed of 64kts or more
|
|
ocean eddies
|
rotating masses of water that have broken off from a strong front/current.
i.e. gulf stream resulting in salinity and density variations. |
|
sea wave
|
waves that have been created by local winds
|
|
swell waves
|
seas that have moved out and away from the area tin which they were formed
|
|
temperature
|
sound speed decreased at lower temps. speed increases 6ft per sec per degree
|
|
pressure
|
pressure increases with depth and sound speed increases with higher pressure. sound speed increases 2ft per sec per 100ft of depth
|
|
salinity
|
slight effewct in open ocean. major fact in shallow water.
|
|
standard refraction
|
refraction that would take place in an idealized atmosphere where the refractive index is reduced uniformly with height.
|
|
super-refraction
|
radar beams bends toward the ground instead of continuing upwards, usually caused by night cooling or marine inversion
|
|
sub-refraction
|
causes radars to overshoot target that are normally detected. usually occur in desert regions and mtn ranges
|
|
trapping/ducting
|
extension on super-refraction. can extend radar ranges.
|
