A detailed catalogue of naked-eye sunspots from Far Eastern annals is compiled from both the pre-telescopic and telescopic periods. Analysis of these fragmentary records indicates a mean period of about 10 years.作者: delegate 時(shí)間: 2025-3-22 13:07 作者: saturated-fat 時(shí)間: 2025-3-22 17:19 作者: Type-1-Diabetes 時(shí)間: 2025-3-22 23:48

The Pattern of Large-Scale Convection in the Suntation axis. This picture has been called ‘cartridge belt’ convection or ‘banana cell’ convection. The theoretical reasoning behind this pattern is that the Taylor-Proudman theorem for a rotating fluid constrains the fluid to be as near two-dimensional as is consistent with spherical geometry.
