The image on the left below shows
the average amount of incoming solar radiation that
reaches Earth's surface each month. Greenish areas show
where the amount of solar energy coming into Earth is
greater than the amount of heat energy leaving the surface
(a net gain of energy). Bluish areas are where there
is less incoming energy than escaping heat energy (a
net loss of energy).
The image on the right shows the average land and sea surface temperatures for each month. Reds and oranges indicate high temperatures, and blues and violets represent low temperatures.
