During heavy snowfalls, meteorologists measure rainfall every 20 minutes.
More than 100 centimeters of snow have fallen in Moscow since the beginning of the winter season, which is 69 percent of the annual norm, which is 152 centimeters.
This winter, the first snow fell on November 20, and a stable snow cover fell in December. January was the snowiest with 56 centimeters of precipitation. However, this figure cannot be called abnormally large. For comparison: in January 2016 there was almost twice as much snow – 114 centimeters, in 2017 – about 70 centimeters, and in 2018 and 2019 – over 60 centimeters.
Since the beginning of the winter season, experts have recorded 29 transitions of temperature through zero – from positive to negative values. 12 frosts occurred in November. Coping with the effects of extreme temperature fluctuations on utilities is more difficult than snowfall or frost. It is important to react very quickly so that ice does not have time to form on the roads and sidewalks.
Weather forecasts help to act promptly. The complex of the municipal economy has its own meteorological office, which sends the most accurate weather information around the clock, now and in the near future. Datasheets allow you to navigate in time and adjust the cleaning of roads and pedestrian zones.
Specialists of the meteorological service monitor precipitation, wind speed and direction using ultrasonic sensors, and the height of the snowfall is measured with special laser beams. During heavy snowfalls, this is done every 20 minutes and changes are reported non-stop.
39 automatic road stations and 45 weather sensors transmit information about the amount of precipitation. All of them are located near the main metropolitan highways. Reports are received every three hours. Based on these data for 2020, forecasters prepared 128 thousand forecasts for utilities.
