In section one, by using fice scheme and time - gcm, a model of trace gases and oh airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and oh airglow are analyzed. the result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. in this process, gravity wave undergoes growth, overturning, convection and breaking
在第一部分的工作中,利用全隱歐拉格式和全球熱層-電離層-中間層-電動力學環流耦合模式( time - gcm ) ,對重力波的非線性傳播及其在傳播過程中對中高層大氣中氧族和氫族成分和與之密切相關的oh氣輝輻射的影響進行了數值模擬,結果表明,從對流層向上傳播的重力波經歷了產生、發展、飽和、對流產生直至破碎的非線性演化,大氣的非等溫結構加速了重力波在中層頂區的破碎,重力波的非線性傳播是小尺度對流和湍流產生的一個重要的源。Many planets ( for example, ganymede, mercury, the earth, jupiter and saturn ) and stars ( for example, the sun ) possess intrinsic magnetic fields. the explanation for their existence and variation remains a great challenge to planetary scientists and astrophysicists. this article attempts to review some recent developments and difficulties in the study of magnetohydrodynamics for the electrically conducting fluid interiors of planets and stars. it is the fluid motions, usually driven by thermal convection, that generate and sustain magnetic fields through magnetohydrodynamic processes in planets and stars. in planets, the magnetohydrodynamic processes are strongly affected by the combined and inseparable effects of rotation, magnetic fields and spherical geometry. the key dynamics involves the interaction between the coriolis and lorentz forces. in the sun, it is the solar tachocline, a thin shear flow layer located at the base of the convection envelope, that plays an essential role in the solar magnetohydrodynamic processes which produce the 11 - year sunspot cycle. some results of a new nonlinear three - dimensional solar dynamo model are also presented
許多行星(如木衛三,水星,地球,木星和土星)和恆星(如太陽)具有內部磁場.對這些磁場的存在和變化的解釋對行星科學家和天體物理學家是一個巨大的挑戰.本文試圖總結行星和恆星的導電流體內部磁流體力學研究的新近發展和困難.一般由熱對流驅動的流動通過磁流體力學過程產生並維持在行星和恆星中的磁場.在行星中磁流體力學過程強烈地受到轉動,磁場和球幾何位型的綜合影響.其動力學的關鍵方面涉及科里奧利力和洛倫茲力間的相互作用.在太陽中其流線,即處于對流層的薄的剪切流層在太陽的磁流體力學過程中扮演了一個基本的角色,並由之產生了11年的太陽黑子周期.本文也給出了一個新的非線性三維太陽發電機模型Then, we caculate the dynamic character of the reflective mtn cell with the optimized parameter, give out the distribution of velocity, twist angle and tilt angle at the midle of the mtn cell when switch on or off in consideration of the backflow
