Distribution of global temperatures

Here is what you should have noticed:

• latitudinal change
• N.H. - difference between land and ocean
• U.S. west coast (upwelling and cold current) v.s. U.S. east coast (gulf stream)
• influence of gulf stream in north Atlantic
• highest temps are in the subtropical N.H. desert regions
• west coast of S. America is cool while the east coast is warm, due to the ocean currents
• much less variability in the zonal direction in the S. H.
• coldest mean temps are over Antarctica, yet the figure to the right suggests it is over the arctic.....?
