Initial data
Bangkok visited a natural phenomenon similar to a tornado in the clouds. The pilot Cherdfong Visaratanont at the airport in Bangkok (Thailand) saw an inexplicable phenomenon: something similar to a tornado was moving on top of a large cumulonimbus cloud. The phenomenon did not disappear from the eyes for a long time, thanks to which the eyewitness filmed 4 minutes of video.
Another pilot saw red sprites and blue jets, but this is something completely different. It is surprising that the human eye cannot see stratospheric lightning over thunderclouds, because they last only a few milliseconds.
The phenomenon in the sky (tornado in clouds) over Bangkok existed much longer and occurred directly on the upper border of a large cumulonimbus cloud. Perhaps the pilots observed a kind of so-called false sun, which occurs due to the refraction of sunlight in hexagonal flat ice crystals, which make up high clouds.

Hypotheses
Halo
Halo usually appears around the Sun or moon, sometimes around other powerful light sources such as street lights. There are many types of halos, but they are mostly caused by ice crystals in Cirrus clouds at a height of 5-10 km in the upper troposphere. The form of the observed halo depends on the shape and arrangement of crystals. Reflected and refracted by the ice crystals, the light often turns into a spectrum, which makes halo look like a rainbow, but a halo in low light has a low chroma, which is associated with the peculiarities of twilight vision.
Investigation
Crown flash is a phenomenon that represents a column of light located in the clouds and performing movements similar to a dance. Often during this phenomenon, the observer hears clicks, pops and similar sounds.
This rare atmospheric phenomenon is an ordinary halo, which is affected by an electromagnetic field. Ice crystals in the air reflect and refract sunlight, forming a halo (false sun). The electro-magnetic field in the cloud can change the orientation of these crystals in space, thereby changing the shape of the "false sun"/light column.
