There is historic evidence that influenza pandemics are associated with solar activity cycles (the Schwabe-cycle of about 11-years periodicity). The hypothesis is presented and developed that influenza pandemics are associated with solar control of vitamin D levels in humans which waxes and wanes in concert with solar cycle dependent ultraviolet radiation. It is proposed that this solar cycle dependence arises both directly from cyclic control of the amount of ultraviolet radiation as well as indirectly through cyclic control of atmospheric circulation and dynamics.
有历史证据表明，流感大流行与太阳活动周期（约 11 年周期性的沙卜周期）有关。本文提出并发展了这样一种假说，即流感大流行与太阳对人类维生素 D 水平的控制有关，这种控制与太阳周期依赖的紫外线辐射同步增减。有人提出，这种对太阳周期的依赖既直接源于紫外线辐射量的周期性控制，也间接源于大气环流和动力学的周期性控制。
