Abstract
The measurement data of the radiosonding network are the basis for the analysis and forecast
of weather, meteorological support of aviation and the armed forces, other forms of operational services
to the population and the national economy. The Roshydromet radiosonding system does not
fully meet the requirements for accuracy and the required amount of information received, especially
in the Arctic region of Russia. In addition to the insufficient density of the aerological observation
network in the Arctic, one of the main problems affecting the prognostic significance of a single release
is the low height of the radiosonde level and, accordingly, the small volume of radiosonde data received,
depending on the quality of the radiosonde balloons. Every year during the winter period in
the Arctic there is a critical decrease in the radiosonding altitude associated with a decrease in temperature
in the stratosphere. According to the results of the analysis of the radiosonding heights in the
Arctic, the effect of increasing the height of the radiosonde in the daytime associated with heating of
the radiosonde balloon by direct solar radiation was established. The difference of heights “day-night”
reaches 18 km. The article considers the possibility of using the obtained results of research and testing
of “winter” balloons in the Arctic to increase the volume of radiosonding data obtained.
