平流的 meaning in English
advectional
advective
Examples
- The in of nonlinear advection into the model weakens the intensity of both inward and outward propagation of vorticity , but makes the inward propagation up to a posi
非线性平流的引进，使涡量向内区传输以及向外传输的强度均减弱：但内传的涡量更加接近于台风中心。 - The azimuthally linear advection may results in that the meso - scale vortex of initially circular shape becomes the elongated and spiral vorticity bands ; the radial linear advection may transfer the vorticity of the outer region towards the center of the typhoon
沿e方向的线性平流可使初始圆形的中尺度涡旋演变为狭长的螺旋状的涡量带;沿径向线性平流的引进可使外区涡量向台风中心方向传播。 - The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation
结果表明：在中高层暖性高压脊及地面变性冷高压稳定维持的大尺度背景条件下，地表净辐射引起的近地层冷却是大雾过程的触发和加强机制；中低空下沉气流的存在有助于近地层的弱风条件和稳定层结的建立；低层暖平流的输入和边界层的浅层抬升是大雾长时间持续的原因；伴随冷空气南下的偏北大风是驱使大雾消散的动力因子。 - The non - local nonlinear advection possesses the duality : on one hand , compared with the linear circumstance , it increases the inward - propagation of vorticity , thus favorable to the strengthening of the typhoon ; however on the other hand , the inward - propagating vorticity destroys the concentric circle structure of the typhoon circulation , leading to the weakening of the typhoon
非局域非线性平流的作用具有两重性:一方面，与线性情况相比，可使内传涡量增加，这有利于台风增强;另一方面内传的涡量又破坏了台风环流的同心圆结构，这使台风趋于减弱。 - There are two parts in this paper : firstly , a set of single doppler velocity models are presented for typical ambient windfields that include those of being uniform horizontally , macroscale convergence and divergence , which overlap warm and cold advection . which are marked by different signatures in the single doppler velocity field . the models proposed can help users identify useful information from the dopple velocity patterns
