降水区上空的涡度、散度、比湿、水汽通量散度、 k指数等要素有利于暴雨的形成和发展。 - We also analyzed the elements of vorticity , divergence , specific humidity , moisture flux divergence , wind - field , wind shear , maximum lifting speed and so on in the snow - storm of north - east china , found that they are favorable for and benefited to the formation and development of snow - storm
对2000年1月同一天不同时刻发生在西北和东北的一场暴雪过程进行了对比分析，发现两地暴雪虽发生在同样的大尺度环流背景下，但却在很多方面有不同之处。 - The results of numerical experiments , using the four - dimensional variational data assimilation system of the nonhydrostatic mesoscale model mm5 , show that : the tangent linear model and adjoint model conducted by keeping the " on - off " switches the same as the basic state , can provide a good approximation of the first - order information to the nlm perturbation and a good descent direction for the minimization procedure ; switching on and off at every other time step in the kuo cumulus parameterization scheme do n ' t impact the convergence rate of cost function ; the existence of the switches do n ' t impact improvement to the mm5 model rainfall prediction because that not only specific humidity , but also wind , temperature and pressure are assimilated into the model
非静力中尺度数值模式mm5的四维变分资料同化系统进行的数值试验结果表明： “开关”变量保持与基态一致，所构造的切向线性模式能够提供关于非线性模式扰动的一阶近似，伴随模式所计算的梯度值能够为最小化过程提供较好的下降方向；郭氏降水参数化方案中对流每隔一个积分步的交替发生并不影响目标函数最小化的收敛速度； “开关”变量的存在也不影响将风、温度、气压和比湿结合起来同化对mm5降水预报准确性的提高。 - The variations of sea ice in the arctic ocean are simulated by using a improved high resolution hibler dynamic - thermodynamic sea ice model during 1979 - 1998 . the model is driven by surface atmospheric and oceanic forcing consists of geostrophic winds , surface air temperature , specific humidity , and longwave and shortwave radiative fluxes provided by international arctic buoy program ( iabp ) . the simulated results show that arctic sea ice have noticeable seasonal and annual variability
利用一个hibler海冰热动力模式，在改进了其热力部分和改变模拟范围以及提高分辨率的基础上，以北极国际浮标计划( iabp )提供的1979 - 1998年间逐日变化的日平均海平面气温场，湿度场，长短波辐射场，风场，洋流场，海洋热流量场为强迫场，模拟了上述20年间北极海冰的时空演变。 - The thesis focuses on the development of the dynamic simulation model of evaporators , the accomplishment of the stable and dynamic simulation of the parameters of cryogen - side , air - side and how to carry out dynamic simulation on the refrigerating effect of evaporators under different evaporating temperature and the realization of the analyses and calculations of the main parameters , such as , the wind speed of air - side and specific humidity etc , which affect the function of evaporators
本文重点是对蒸发器建立动态仿真模型，并对制冷剂侧和空气侧参数进行稳态和动态仿真，同时对蒸发器在不同蒸发温度下的制冷量进行了动态仿真，而且对影响蒸发器性能的主要参数(空气侧入口风速、入口含湿量等)进行了分析和计算。
