本文以8006和8309两个台风为例,分析了近海台风的结构,指出其重要特点是运动场和热力场的显著不对称和只有弱的暖心。本文还着重对它们在近海及登陆后的总动能和涡动动能收支及加热场情况,进行了对比诊断研究。指出近海台风的不对称结构... 本文以8006和8309两个台风为例,分析了近海台风的结构,指出其重要特点是运动场和热力场的显著不对称和只有弱的暖心。本文还着重对它们在近海及登陆后的总动能和涡动动能收支及加热场情况,进行了对比诊断研究。指出近海台风的不对称结构中,隐含着消亡机制,这是由于不对称的暖区和上升区都偏离台风中心且不相一致,使台风区有效位能向动能转换的过程很弱甚至反向。另外,如台风登陆后继续维持热带系统特点,未能迅速将主要能源由潜热释放转变为斜压过程,也易迅速消亡。在加热场方面,登陆后迅速减弱的台风,最大加热强度较大,其所在层次也较高。 展开更多

Two forms of basic equations and 5 basic matrices in the matrix analysis of networks from nonlinear networks to linear networks are obtained and their origins in physics are correctly explained. Furthermore, the whole 12 general characteristic formulae of the 4 fundamental network elements as well as some important new results, which were not in the conventional theory, have also been obtained during inference for both nonlinear and linear networks. 展开更多

A field theory has been proposed. The laws of conservation of charge and energy can be obtained from the Maxwell’s equations, which are placed in nonlinear network for simultaneous solution, and therefore the Kirchhoff’s law with its most fundamental integral formulae in nonlinear network can be obtained. Thus, it will strictly push forward the total basic equations from non-linear network to linear network as well as other important new relationships to provide the theoretical grounds for the field theory. 展开更多
