Document Summary
On earth, atmospheric convection is driven by solar radiation. Jupiter & saturn are radiating more energy into space than they receive from the sun. Jupiter"s weather is driven from w/in the planet. Heat left over from planet accretion or released by ongoing contraction & Infrared photos of jupiter show areas where heat is escaping from the interior. Jupiter emits twice as much radiation as it receives from the sun its atmosphere is differentiation warms the base of the atmosphere, driving convection heated from below more than it is from solar radiation. We can measure the total energy released by a planet & compare it to the energy the. On earth, there are in balance when one accounts for albedo effects. The aount of energy we receive from the sun is vastly larger than that released from the. Jupiter & saturn emit much more energy than they receive. Differentiation releases gravitational potential energy, which is converted to heat.
