November 29 we celebrated the complete freezing of the Moscow River, which was in line with the general weather conditions. At this point, everything in our area was covered with snow.
After that we did not have the opportunity to attend the riverbank, but considering that approximately December 1, the thaw began, we expected that the river will reveal barely formed from ice.
Indeed, where a two weeks later in the same place it was possible to observe such a picture.
This is a picture of 13 December. More snow, but ice is not there ...
Last year, on November 29 the river was also under the ice, but the ice was very thin, and in the beginning of December, we noted already confident enough ice. But then the data is not present, so we can not say with certainty that in December, the ice did not go ...
Waters near the town of Klimovsk, where he lives our friend the naturalist Paul Antoshkin covered with ice. Last year, for the first time this dammed river froze Petrica October 21, but then the ice melted and then lay around November 24th. This year, freeze-up was completed by 28 November, and ice were first fishermen. We can assume that this is the average time for the reservoir.
And like last year, the Moscow River in our Krylatskoye comes with Petritsi near Moscow head to head!
November 29 the whole river constrained for quite a thick layer of ice on the shore its thickness is 2-3 cm.
And most interesting is that last year, on November 29 the Moscow River, too, lay the ice, and before that we have noted rising river on November 19 and then came down the ice.
We remind you that meteorologists believe that the Moscow river should freeze to the 18th of November. This year we have, unfortunately, there is no data on the behavior of the river until 29 November.
Finally, we can say with confidence: the Moskva River at the site of our observations stood up!
But with certainty it? Meteorologists, it turns out, believe that the Moscow River freeze put in an average of 18 of November. And we have the second year freeze in early December ... Maybe we're some kind of improper phenomenon freeze-believe? Returning from the river on December 2 met the fisherman, who said yesterday that the ice was 10 cm, that is, the river is already possible to go. With the freeze-up ?!
Our friend and member of the project from Klimovsk reports that their pond froze again and they opened the season skating. A week ago, the ice on the pond was not. In other words they dammed the river began to be covered with ice in the same period as the Moscow River. But unlike a large and fluid on the Moscow River dammed pond ice lay standing firmly.
By the calendar of nature, which year after year leads a wonderful writer and experienced naturalist Anatoly Sergeyevich Onega, we learned that "October 20 - the day of St. Sergius - if Sergius snow, the winter need to wait for the November Matrevu (November 22) ... So while everything develops - in Moscow, alas, still snowless winter (frost, anticyclone no inclination to warming). " Indeed the first ice on the river we found on November 19, and November 20, met a pond near the frozen MSU appeared confident.
And again, we continue to monitor the establishment of the ice cover. All natural processes (and in wildlife and inanimate) require consistent observation day by day. But then very interesting to compare the observations for different years.
Begin a new round of our ice project! Thanks to last year's results and analysis that carefully conducted our students, while another third graders, we have defined the data for the previous year, with which we can compare the data of the year.
It is believed that the water bodies of the European part of Russia begin to freeze in the second half of November and the first half of December, the ice cover is installed. In our school for the third year to observe the process of freeze-up on the river Moscow, to which the school building from the doorstep. We are very interesting to compare their results with the observations of other participants GlobalLab.
