Two unusual forms of inferior mirage are observed and photographed at the Halligen Sea. With heuristic analytic functions for the temperature profiles, numerical integration of the refraction differential equation on a flat earth is performed. The simulation shows that a double inferior mirage can appear if a light wind carries hot air from above dry sandbanks in the mud flats. Horizontal stripes can appear in the mirage image if a water channel crosses the line of sight between the observer and the object.
在哈利根海观察并拍摄到了两种不同寻常的下蜃景形式。利用温度剖面的启发式分析函数,在平坦地球表面上对折射微分方程进行了数值积分。模拟结果表明,如果微风将热空气从泥滩上干燥的沙洲上方吹过,就会出现双重下蜃景。如果一条水道穿过观察者与物体之间的视线,蜃景图像中就会出现水平条纹。
