We encountered a solid cold front at 16,000 feet (5,000 meters).

我们在5000米的时候遇上强劲冷锋。

A cold front is moving in from the north.

一股冷锋正从北方向这里移动。

According to the forecast, a cold front is moving towards this region.

根据天气预报，一个冷锋正向这个地区移动。

Results show that existence from strong convergence of water vapor and the conditional convective instability in the middle and low troposphere probably provided the suitable environment for heavy rainfall.

分析表明，对流层中低层水汽的大量集中以及对流不稳定条件的存在可能对此类系统发展提供了有利环境，对其启动的机制作了初步的讨论，认为地形的动力强迫和地面冷锋以及低空急流扰动可能对此类系统的发生发展起了触发作用。

A cold front is the forward edge of a mass of moving cold air .

冷锋就是移动的冷空气团的前锋。

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。

The strong sandstorm was caused by squall line activity of eastern Hexi Corridor in Apr. to Jun. that was cold front, majority is in May, four times strong sandstorm is accompanied by the squall line in seven times. It was explained that the squall line was suggested easily when the strong cold front moved east to Hexi Corridor where special canyon tube terrain was in, the strong sandstorm which was created by squall line activity have very strong paroxysm that often created serious disaster.

河西走廊东部的飑线活动造成的强沙尘暴出现在4~6月，均为冷锋型，其中5月居多，出现的7次强沙尘暴中有4次伴有飑线，说明5月份强冷锋东移经河西走廊特殊峡管地形时易诱发飑线，飑线活动造成的强沙尘暴爆发性强，往往造成严重灾情。

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。
