Specialized Biometeorological Indicator

Abstract

The purpose of the study is to improve the meteorological support of aviation units functioning in hot climate areas by developing a specialized biometeorological indicator to assess the safety of personnel working in open terrain in conditions of elevated temperatures. Methods and materials. The indicator model is based on Harrington’s approach (the generalized desirability function). Information base was compiled by: observation data of meteorological stations of Roshydromet network: Upper Baskunchak, Volgograd, Astrakhan, Alexandrov Guy, Sochi; reanalysis of atmospheric parameters NCEP/DOE materials; World data Center resources (observation data of meteorological stations in the Middle East). Results. The model of specialized biometeorological indicator that meets the requirements of supporting weather-dependent decision-making by management bodies was built. The model takes into account the physical load of personnel and the technological period necessary for the preparation/maintenance of equipment. Software package for automated calculation of the indicator is developed. The spatial distribution of this indicator in various forms is given. Efficiency of indicator application is calculated. Conclusions. The use of the developed indicator can contribute to improving the meteorological support of aviation units in the hot climate of summer season (comparison with the heat stress index WBGT, the application of specialized indicator gives an increase in quality by 3–8 % depending on the climatic conditions of the area).
