The rotation of the earth drives the non-equivalently distributed positive and negative charges to move around the earth's axis in a circle to generate the earth's main magnetic field stationary relative to the earth's axis and form the earth's electric field. The charged particles driven by the earth's rotation are subject to the action of the earth's electric field and the earth's main magnetic field. In order to explore the natural causes of the earth's climate change,create geomagnetic reference system stationary relative to the geo-axis,applied classical physics theories and methods to analytic study the laws of movement of charged particles in the earth's electric field and the earth's main magnetic field. The results show that: Both the climatic zone and the seasonal rhythm result from the coactions of electromagnetic force,thermal power and gravitational attraction; The changes of the earth's electric field and magnetic field make the electromagnetic force subject to charged particles in the earth system change,and the impact on climate is omni-directional. The atmosphere has a certain function of automatic regulation,the extreme trend of contemporary climate is closely related to the extremely weak of the main magnetic field of the earth in the atmosphere. The conclusions of this study summarized in four aspects: ( 1) The earth's electric field causes the positively-charged particles and negatively-charged particles in the atmosphere to be staggered and stratified,and the space charge densities in the south and north poles of the earth and those near the equator are high. ( 2) The earth's main magnetic field makes the positively-charged particles and negatively-charged particles in the atmosphere convolute in opposite directions in the plane perpendicular to the earth's main magnetic field,and drive the charged atmosphere to form cyclones and anti-cyclonic circulations. ( 3) The law of the charged atmosphere gyrate is as follows: Under the condition of constant linear velocity, the swirling radius of the charged atmosphere is inversely proportional to the product of the magnetic flux density of the total magnetic field and atmosphere charge-to-mass ratio; The magnitude of the swirling angular velocity is equal to the product of the magnetic flux density of the total magnetic field and atmosphere charge-to-mass ratio,and independent of the linear velocity; The velocity of charged atmospheric relative to the ground is asymmetrical in each quadrant. ( 4) The earth's electric field,earth's magnetic field,motion of charged atmosphere together with the correspondingly induced electric and magnetic fields obey the classical physics laws of Maxwell's equations and Newton's laws of motion etc. They are an entangled whole, with hyper-medium telerelation and teleresponse mechanisms,can cause polar molecules in the atmosphere to ionize, a local electromagnetic field with anomalous changes before the earthquake can form an earthquake cloud in the atmosphere. The induced electric and magnetic field can couple the gyrating charged atmosphere along the longitude and latitude directions to form the longitude and latitud directions dipole type atmospheric circulation and latitudinal annular type atmospheric circulation,and make it closely related to the electromagnetic characteristics of underlying surface medium. The gyrating of charged atmosphere has a positive feedback mechanism,and can form typhoon,tornado,etc. as the charge-to-mass ratio increases. The circulation systems with different scale in the atmosphere,ranging from the eastern ( westerly) wind belt,Southern ( Northern) Hemisphere Annular Mode,to Tropical Cyclones, etc. all are caused by the motion of the charged atmosphere driven by the earth's electric field and the earth's magnetic field. Quasi-steady planetary waves are the result of the propagation of induced electromagnetic fields of large-scale circulation systems.
