– It turned out that at temperatures around zero and below, even a small breeze affects the rate of icing. Like an undercurrent, it introduces fluctuations (jumps) in temperature and this, in turn, leads to an acceleration in the formation of crystals, – says Evgenia Makoveeva, co-author of the study, lead researcher at the Laboratory of Sciences of the Federal University from the Urals. Multiscale Mathematical Modeling.
And although these so-called external noises are only part of the complex process of freezing water, the data obtained will help predict changes in glaciers in the world’s oceans, something very important in a warmer climate.
In the next stage, the physicists want to calculate how a “false bottom” forms when the ice freezes from below. Therefore, it can grow up to 50 percent of the ice.
– It occurs in the spring-summer period, when the ice is looser, allows melt water to pass through, and a fresh layer forms. And below, a layer of salt. And in the place where they come together, ice crystals are born, – explains Makoveeva.
