Unit 2: Fluid Dynamic Flashcards
Major characteristic properties of waves include:
Amplitude, frequency, wavelength
what does the wave move in the direction of propagation
It does not move mass in the direction of propagation; it transfers energy
Which way do longitudinal waves oscillate?
They oscillate in the direction of propagation and do not displace mass
The particles which make a water wave move in:
Circular path
Which way is the energy of a wave transported?
Perpendicular to the direction of the waves transportation
The times and amplitude of the tides a t a locale are influenced by several factors, such as:
- The pattern of tides in the deep ocean
- The shape of the coastline
- the alignment of the sun and moon
The Coriolis effect is caused by the
Rotation of the Earth around its axis
The Coriolis force is proportional to
It is proportional to the object’s mass and speed in the rotating frame
Tidal and Coriolis forces may be not obvious over a small time=space scale, but they are important in
Meteorology, navigation, and fishing
Which type of tide has one high and low tide or day with a period of 24 hours and 50 min?
Diurnal
Which type of tide occurs when the sun, earth, and moon are in line with each other?
Spring Tides
Which type of winds blow from the southwest and occur between 30 and 60 degrees latitude?
Westelies
Which type of current is produced by water from cold polar regions that sinks and flows beneath warm ocean water toward the equator?
Deep currents
Term which refers to a large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures around December across the central and east-central Equatorial Pacific
La Nina
The main different between climate and weather is
Climate is a long-term manifestation of weather patterns; weather is short-term
