On air "sensed temperature" in Russia’s northern regions and its significance for geological prospecting
Research aim is digital estimation of air "sensed temperature" for Arctic and other cold areas of Russia. Relevance of the work is determined by Arctic geological survey for oil and gas prospecting. Research methodology includes the generalization of the results of previous studies and the application of some new ideas. Results. All measures of temperature senses can be divided into two classes: those based on the thermal balance equation and empirical ones. Without exception, no "effective " temperatures have a universal character and their use is good only for those regions for which they were developed. For Siberia and Russian Arctic segment, it is possible to apply "reduced temperature" by Adamenko-Khairullin based on information on wind speed, air temperature and radiation balance. The latter can be measured with actinometers or estimatedfrom publications. Sphere thermometer readings give directly sensed temperature provided that the sphere has a proper diameter. Nevertheless there is not onevalued universal methodology to calculate air "sensed temperature" mentioned in weather forecast. The authors simplified "sensed temperature" calculations as much as possible. Field of implementation. Digital estimation of air "sensed temperature" is essential for geological prospecting in the northern territories of Russia. Conclusion. There is an objective need in "sensed temperature" calculations including operational decisions in industries working in Arctic conditions. Three simple but effective formulas for "sensed temperature" of air were supposed for the biggest part of Russia ’s northern territories.
