Angry birds? It seems I see a governor operating. Amazing the difference between the landed northern hemisphere and the more open southern hemisphere, with its growing continental ice sheet in the pole position. Awe inspiring indeed.

Watts Up With That?

To continue my investigations utilizing the CERES satellite dataset of top of atmosphere radiation, here is a set of curious graphs. The first one is the outgoing (upwelling) longwave radiation at the top of the atmosphere (TOA) versus the sea surface temperature, for the northern hemisphere, at the times of the solstices and equinoxes.

dec upwelling longwave vs sea temperatureFigure 1. Northern HemisphereTOA outgoing longwave, versus sea surface temperature. Colors represent latitudes, as follows: dark blue, 10°; red 30°; yellow 50°; sky blue 70°. Vertical dashed line is at 30.75°C. Horizontal dashed line is at 300 W/m2. Black solid line shows the surface upwelling longwave radiation (calculated at emissivity = 0.95). Click to enlarge.

I find this graph both interesting and puzzling.
