地磁场的形成和演进与全球气候变化的关系

The Relationship between the Formation and Evolution of Geomagnetic field and Climate change

人们早就发现地磁场与气候变化紧密相关,但并未明确地磁场变化与气候变化的真正因果关系。为此作者重新研究了地磁场的形成和变化机制,发现地磁场的变化完全受控于大气的运动和变化。当地球处于间冰期时,大气层在太阳紫外线和宇宙射线的作用下能产生大量的正离子和负离子,然后形成云上正电荷层和云下负电荷层,伴随地球的自转就产生了叠加的地磁场。这种磁场符合人们已发现的地磁场的所有特点,能够很好地解释地磁场空间分布的不均匀性和随时间不断变化的特性,包括磁偏角和地磁倒转的现象。当地球处于冰期时,陆地和海洋被冰雪覆盖,云下层接地,云下层负电荷变0,云上层正电荷在地磁场的形成中起主导作用,使地磁场极性倒转。其他星球磁场的形成原因与倒转规律类似。

Geomagnetic field has long been found to be closely related to climate change,but the real causal relationship between geomagnetic field change and climate change isn＇t clear yet.So the author has researched the formation and evolution of the geomagnetic field again,and discovered that the variation of geomagnetic field is completely controlled by the change of climate.That is,during an interglacial period,under the action of solar ultraviolet rays and cosmic rays,Earth＇s atmosphere can produce a large amount of positive ions and negative ions, then form the positive charge layer at the top of cloud and the negative charge layer at the bottom of the cloud;with the rotation of Earth, the two charge layers generate a superposition of geomagnetic fields.This kind of magnetic field conforms to all the known characteristics of geomagnetic field.It can well explain the inhomogeneity of the spatial distribution of geomagnetic field and its characteristic of constant change over time, including geomagnetic declination and geomagnetic reversal.If the Earth enters an glacial period,the land and the sea would be covered by ice,then the bottom of the clouds would touch the ground, making the charge at the bottom of clouds become 0 and the surface charge be approximately equal to 0.At this time only the positive charge layer at the top of cloud has an effect on forming geomagnetic field,therefore realizing geomagnetic reversal.The formation and reversal of other planets＇ magnetic fields are similar with that of geomagnetic field.
