What Makes the Oceans Go? The linked ocean and
atmosphere
1) What forces drive ocean currents? 2) General
North Atlantic Circulation 3) Gulf Stream flow
along the US east coast 4) Ocean/Atmosphere
Interactions (Coastal Upwelling) 5) Where the
river meets the sea

Looking at the earth from the top down, you can
see that the farther north one travels,
the shorter the distance is along a parallel of
latitude (the circles get smaller).

Just remember that water in motion deflects
to the right in the northern hemisphere
(left in southern hemisphere)

Sea Breeze along the New Jersey Coast Ocean
drives the Atmosphere
53
What is a sea breeze?

• Develops as a result of the land/sea temperature
  gradient

Atmosphere
54
Who does the sea breeze affect?
Radar Reflectivity from Doppler radar

• Develops as a result of the land/sea temperature
  gradient
• Can occur during almost any month of the year
• Can affect almost all of New Jersey and into
  SE Pennsylvania
