"Puzzling Snow Formations Captured by Photographer in St. Petersburg"
St. Petersburg photographer Anton Kubyshkin captured some peculiar-looking snow formations in Udelny Park on February 3. The photos, shared in the "Mushrooms and Mushroom Pickers of St. Petersburg" community, resemble snow needles, but the weather conditions didn't seem suitable for them, according to a weather forecaster.
Kubyshkin, expressing surprise at the
unusual snow shapes, shared the pictures and questioned whether he might be
overlooking something in the snow. A specialist from FOBOSA suggested that the
photos might depict a type of winter solid precipitation called ice needles.
These are tiny ice crystals that form in extremely cold weather (below
-10...-15 °C). Ice needles often create beautiful glowing pillars extending
from lanterns into the sky, especially during nighttime or dusk.
However, the specialist mentioned that,
given the current positive temperatures and precipitation, it's unlikely that
such snow would form. Ice needles typically appear in clear or partly cloudy
skies, seemingly freezing out of the air, and are rarely associated with cirrostratus
or cirrus clouds. They are sometimes referred to as clear sky precipitation.
