Columns of light of various colors shone in the Winnipeg sky on the night of December 31st. This rather spectacular phenomenon occurs under “unique conditions,” points out Jacques Bourgeois, director of communications and marketing at Marais Oak Hammock in Manitoba.
A light column is a kind of pillar of light that appears to arise from a point of light, indicates the science communicator. Winnipeg’s city lights were the light source for the columns seen on New Year’s Eve.
For these pillars of light to form, you need “a cold temperature, but also a saturated atmosphere in which water will form into ice crystals rather than snowflakes,” adds Bourgeois. The weather must also be very calm, without wind, so as not to move these crystals.
“It is the light that will reflect on these small crystals and that will make us appear as a sort of large jet of light rising towards the sky. »

Jacques Bourgeois states that although this phenomenon is best observed from outside the city, those in the city can also see it.
