天灾成因的外核对流说

Causes of natural disasters based on the outer core convection hypothesis

本文提出,天灾(旱、涝、震等)的成因是外核强对流运动.与对流层大气运动进行类比可知,外核流体的运动亦可分为对流和平流两类,对流上升泡对壳幔层的顶托作用使地壳脆性层中应力积累酝酿地震.因顶托撤销,而使地内应力突降,是地震发生的直接原因.在外核垂直速度的水平切变最强处,往往是震中所在地.固体圈层的能量流主要是压缩和拉张两类,因压缩通过共振而在地表层形成的"拍涡"是涝灾的罪魁,因拉张而形成的大地冷涡则是严重干旱的祸首.

In this paper, we proposed that the outer core convection movement is the source of the major natural disasters （e.g, drought, flood, earthquake etc）.The movement of the fluid in the core can be divided into convection and advection. At the same time,the convection included rising convective cell and sinking. The earthquake occur when the rising cell thrusts the crust-mantle layer and cause crustal stress accumulated in brittle layer. The epicenter is usually located in the place where the outer core vertical velocity shears most. The two fundamental types of energy flow in the outer core are compression and tension. The ＂Beat Vortex＂ caused by resonance which formed in the ground surface due to compression effects is the chief reason for flood years, while the strong ＂underground cold vortex＂ originated from the stretching effects is regarded as the chief reason for severe droughts.
