Looming and similar refraction phenomena - Wikipedia
Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
What is looming? How is it formed? Explain with figure. - BYJU'S
Looming is a kind of mirage observed in very cold regions in which a distant object appears to be hanging mid way in the air. It is produced by total internal reflection of light caused by atmospheric refraction.
Looming - Wikipedia
Looming is a term found in the study of perception, as it relates directly to psychology. Looming occurs when an object begins moving closer to the eye. As the resulting image becomes increasingly larger on the perceiver's retina, i.e., when an object looms, there is an automatic physiological response to perceive the object as an approaching ...

Mirages and other atomospheric optic phenomena - HyperPhysics
Looming. The looming effect is the result of a superior mirage. A typical example is a mirage of a ship formed over cool water in an area where the temperature increases with height. Refraction bends light down toward the water in this case.
Looming, Towering, Stooping, and Sinking - San Diego State …
When abnormal refraction increases the apparent elevation of distant objects — often lifting above the horizon things normally below it — the process is described as ‘looming.’. Because we associate a certain apparent altitude with a certain distance, this phenomenon generally makes the objects seem nearer than they really are. Looming [align]
Optical phenomenon - Wikipedia
Optical phenomena include those arising from the optical properties of the atmosphere; the rest of nature (other phenomena); of objects, whether natural or human-made (optical effects); and of our eyes (Entoptic phenomena).
OPOD - Looming, Towering, Mock-Mirage, Green Flash
This article explores the fascinating optical phenomena of looming, towering, mock mirages, and the elusive green flash, captured in a sequence of sunset images. By understanding the principles of refraction, we gain insight into these captivating atmospheric effects.
looming - Glossary of Meteorology
Looming occurs when the concave side of light rays from a distant object is down, and this in turn occurs when the refractive index of the atmosphere decreases with height. This is very common, but the displacement is usually sufficiently small as to be unremarkable.
Title: Visual Looming from Motion Field and Surface Normals
Oct 8, 2022 · We present novel methods to estimate visual looming from spatial derivatives of optical flow without the need for knowing range. Simulation results show that estimations of looming are very close to ground truth looming under some assumptions of surface orientations.
