Initial data
Yesterday, Vladimir Chesalin, a well-known entrepreneur in Zhukovka, noticed unusual and incomprehensible phenomena on the holy lake, and he decided to share his impressions with our editorial staff.
"Stripes appear on the smooth surface moving all over the lake, they seem to glow and the water there bubbles or somehow ripples above the rest of the lake surface!", - said Zhukovsky activist.
In addition, Vladimir claims that recently on the lake a group of tourists saw a three-meter water column that stayed above the surface of the lake for about a minute.
The man connects these phenomena with the fact that many years ago there was a church in the place where the lake is now located, with which many legends are associated.
Meanwhile, one of the avid fishermen, who is a reader of Bryansktoday, told us that the phenomenon recorded on the video cannot be called abnormal. According to him, most likely, we are talking about the usual ripples arising from a temperature drop.
This phenomenon can most often be observed in autumn, when the air temperature is less than the water temperature.

Hypotheses
The wind
Wind — flow of air, which quickly moves parallel to the earth's surface.
Wind is the result of uneven distribution of atmospheric pressure and is directed from areas of high pressure to the low pressure zone. Due to the continuous pressure changes in time and space speed and wind direction are constantly changing. With height wind speed varies with the decrease of the friction force.
Winds can affect the formation of the relief, causing Eolian deposits that form different kinds of soils (e.g., loess) or erosion.
Investigation
For lakes, this is really a normal phenomenon. Such ripples are associated not only with the influence of wind, but also with the thermal heterogeneity of water masses and the difference in the concentration of dissolved or suspended substances.
