western boundary currents - (ANSWER)warm, above sea level, western side of oceans, really fast, ~50
s.v., the greater the volume the greater the flow
eastern boundary currents - (ANSWER)cold, eastern side of oceans, western side of continents, slow ~3-
5 s.v., diffuse, spread out
cyclonic circulations - (ANSWER)wind circulation around a low-pressure weather cell. In N. hemisphere,
when viewed above, it is in a counterclockwise pattern.
hurricane - (ANSWER)tropical storm in Atlantic Ocean with wind speeds greater than 74 mph
hurricane warning - (ANSWER)hurricane expected in designated coastal area within 24 hrs
hurricane watch - (ANSWER)hurricane winds are expected in designated coastal area within 36 hrs
Saffir-Simpson Scale - (ANSWER)The standard for measurement hurricane strength, based on minimum
sustained wind speeds
storm surge - (ANSWER)sea level elevation above normal levels at a coastline, caused by tropical storm
winds "piling up" water as the storm approaches land.
typhoon - (ANSWER)a tropical storm in the Pacific Ocean with cyclonic circulation and wind speeds
greater than 118 km/hr.
dynamic topography - (ANSWER)Reading of sea level height based on the speed of currents. Typically
contour lines are used to signify the topography of the water
Ekman transport - (ANSWER)Youtube video at https://youtu.be/zYms4lHpgLc

Geostrophic flow - (ANSWER)persistent geostrophic gyres that flow in all oceans except around
Antarctica. These are the major currents that transport heat in the oceans and they dramatically affect
climate. For example, if the Gulf Stream (a geostrophic current) stopped flowing, the climate of most of
northern Europe would be dramatically colder, becoming much more like Alaska? from

thermocline - (ANSWER)temperature gradient or rapid decrease of temperature with depth in a body of
water; layer in which such a gradient occurs. The permanent thermocline in the oceans between the
levels of about 200 meters and 1000 meters, and separates an almost uniformly warm upper layer from
very cold dense bottom waters.
caballing - (ANSWER)a mixing of two water masses of identical in situ densities but different
temperatures and salinities. The resulting water mass then becomes denser than either of its
components. density factor (DF) of caballing > DF1+DF2
isopycnal - (ANSWER)line of equal or constant density
conductivity - (ANSWER)the ability of a fluid to conduct electrical currents. The conductivity increases
with increased salt content. Salinity may be determined by measuring the conductance of seawater with
an electronic device called a salinometer.
density - (ANSWER)mass per unit volume of a substance. Influenced by temperature, salinity, and
pressure.
downwelling - (ANSWER)a downward movement (sinking) of surface water caused by onshore Ekman
transport, converging currents, or when a water mass becomes more dense than the surrounding water.
Where Ekman transport moves surface waters toward the coast, the water piles up and sinks in the
process known as coastal downwelling. Upwelling and downwelling illustrate mass continuity in the
ocean; that is, water is a continuous fluid so that a change in distribution of water in one area is
accompanied by a compensating change in water distribution in another area. from
