查询词典 orographic

It is found that for the mesoscale mountain of steep slope, the dynamical effect of orographic disturbance weakens cold front on the upwind side and strengthens cold front on the mountain top, the frontal intensity is decreased when front moves downslope rapidly.

另外发现锋面强度也是影响地形扰动与锋面相互作用的重要因素，当锋面比较强时，地形扰动与锋面会发生强的相互作用，在地形扰动对锋面产生影响的同时，锋面的过山会引起地形扰动的强烈变化。

The effects of friction in surface layer on the structure of front and the frontogenesis in boundary layer, the interaction of orographic disturbance with front, the influence of diabatic process and moist process on the frontogenesis are investigated. Second, the occurrence and development of frontal rainbands have been studied extensively through the observational and theoretical approaches near half-century. However, there are still some problems needing further investigations because of the complication of the precipitation process.

关于锋面降水的产生和分布问题，近半个世纪以来，国内外气象学家进行了大量的观测和理论研究，但是由于问题的复杂性，至今仍有许多问题不清楚，我们利用非静力模式对变形场锋生条件下锋面雨带的发生、发展和演变过程进行了数值模拟和分析。

Then, the fronts .of different intensities are superposed on the orographic disturbances and pushed by basic geostrophic flow to climb over the orography.

通过非静力模式讨论了两维地形扰动与锋面的相互作用，研究了不同基本气流，包括正压、斜压、层结强弱差异，不同尺度的地形，包括不同高度和不同宽度，强弱不同的锋面等多种情况下地形扰动与锋面扰动的相互影响，发现地形尺度和气流的性质不同带来的结果是有差异的，中尺度地形使冷锋在迎风坡锋消，在背风坡则是锋生和锋消相间的波状分布，表现为锋面在山顶附近锋生、快速下坡过程中锋消和山脚处锋生的分布特征，这与半地转模式中地形的动力作用使冷锋在背风侧单纯加强是不同的。

In order to simplify the simulation,an idealized slope is used. Simulated results with and without orographic effects are compared and analyzed.

结果发现：平坦地面模拟的回波强度、最大降水强度和累积降水都与实况有相当的差距。

在此基础上利用中尺度模式ARPS模拟，成功再现了此次暴雨过程，并利用模式的输出结果研究了地形动力过程对云和降水过程的影响。

Simulations of echo intensity,maximum precipitation without orographic effects are much weaker than observations;and they are much improved and closer to the reality after consideration of orographic effects.

理想地形的对流过程虽然不能模拟出对流群中多单体的生消过程，但最大降水强度和累积降水都比平坦地面的大，更接近实测结果。
