Making Waves

clipped from wattsupwiththat.com Diurnal solar insolation and temperature variation, daily and monthly lunar tide cycles, seasonal variation of solar insolation by hemisphere, seasonal variation of temperatures by hemisphere, seasonal biomass variations, seasonal sea ice variations, seasonal albedo variations, 11 and 22 year solar cycles, Earth’s length of day variations, El Nino Southern Oscillation, North Atlantic Oscillation, Pacific Decadal Oscillation, Atlantic Multidecadal Oscillation, and at very long periods, Milankovitch cycles. There are many many cycles on earth that are known, some yet to be discovered. Almost all of them have a root cause in periodic circular motions such as planetary rotation and orbital motion in our solar system and the variances of orbital eccentricity, obliquity, and precession. For example, the graph below shows how these different waves eventually synchronize to cause cycles of ice ages on earth.
