Assessment of the evolution of the Northeastern Russia glacier systems using regular grid meteorological data
A methodical approach is proposed for calculating the equilibrium line altitude HELA of glacier systems (on the example of the Northeastern Russia) on the basis of the characteristics that determine it in time and space: from the archive of temperature and precipitation at the grid points (the UDel...

A methodical approach is proposed for calculating the equilibrium line altitude HELA of glacier systems (on the example of the Northeastern Russia) on the basis of the characteristics that determine it in time and space: from the archive of temperature and precipitation at the grid points (the UDel archive, Delaware University). This data is used in the equation of mass balance of the glacier systems for the calculation of its components. As a result, the output is the inter-annual series of deviations of HELA from the mean value and the ratio between accumulation and solid precipitation in the regular grids over the glacial systems. By the longterm series of the HELA deviations the periods of minimum and maximum HELA state were revealed for various glacial systems, as well as linear trends of these series. This made us possible to evaluate the HELA trends in the future using the linear regression method. The sensitivity of the method of the initial parameters – the mean values of the summer air temperature, solid precipitation and the HELA value, received independently, have been estimated. Thus, the method allows detailing the HELA changes in space with the resolution of the archive used, and in time for each year of the selected climatic period. |
