| | Summary: |
| | In this paper, based on publicly available data of daily mean air temperature
in the last 40 years (1.1.1975-31.12.2014.) in the city of Belgrade, a trend in the
temperature increase and an analytic formula for temperature variation as a function of
time, were determined. Spectral analysis and frequency mapping identified the existence
of dominant frequencies, which correspond to perennial, annual, as well as the seasonal
temperature variations. Based upon this information, an analytic formula for
temperature variation for the 40 years period was derived that could be used for longrun prediction of temperature variations. The results of this research could be used in
modeling of unsteady-state heat transfer problems in building physics. |
