From Glossary of Meteorology


A mirage in which the angular height of the image is greater than that of the object.

As the width is unaffected (the angular width of image width remains that of the object because the refractive index gradient is vertical), the aspect ratio is altered and distant images appear vertically enlarged. Towering often accompanies sinking—distant features appear depressed and enlarged—but it can also accompany looming.
Compare stooping.
