波状气流的产生主要基于山的走向、长度、风向风速和大气层结结构。而大风天有赖于秋冬季节由西北入境的冷空气,相适应的山脉也以太行山和贺兰山脉为最佳。至于波状气流的利用,要特别注重飞前滑翔机、氧气设备、天气预报以及地点和飞行路线的选择。在爬高和下降过程中更要注意位置的变化。 The formation of wavy airflow is mainly based on the direction of mountain, length, wind direction and atmosphere structure. The windy days depend on the cold air coming in from the northwest in the autumn and winter. The most suitable mountains are the Taihang Mountains and the Helan Mountains. Special attention should be given to the use of forward-flight gliders, oxygen equipment, weather forecasts and the selection of locations and flight routes. In the process of climbing and falling more attention should be paid to the location changes.
