1·Stratus. These low-lying clouds can give you a strangely claustrophobic feeling. When a stratus cloud forms at a very low level, it is called fog or mist.

层云。这种低垂的云彩“会让你产生一种奇特的幽闭感。”当层云在很低的水平面形成时，它通常被称作雾气。

2·By comparing model simulation with an observed precipitation formed by stratus cloud system, the new scheme shows the improvement of prediction precipitation.

利用新方案模拟了一次层状云降水过程，新旧方案降水模拟结果的对比表明新方案的降水预报效果有所改进。

3·Simulation results show that targets can be found more easily in cumulus or stratus than in undulance cloud, because undulance cloud is more abrupt change in its intensity.

结果显示，在积状云和层状云背景中的目标识别较容易，在波状云中的目标识别较难。
