Western and eastern boundary currents have drastically
different climatic effects!
You determined that the western boundary currents carry
warm water away from the equator, which in turn, transports warm, humid air
-- thus coastal environments along the east coasts of continents have a warm,
humid climate, typically during the summer.
Can you see on the map of sea
surface temperature below, how the
boundary currents influence temperatures on a global scale?
Can you remember the properties of eastern
boundary currents from the previous expedition?
By looking at the sea surface temperature
map, shown above, can you hypothesize about the temperature and humidity of the climate in the
regions of eastern boundary currents?
