Porównanie wielomianu i funkcji Fouriera opisujących roczny przebieg temperatury i wilgotności powietrza w Ursynowie SGGW

The aim of the paper is to compare two methods of estimation main meteorological elements annual course - polynomial function and Fourier function. Long-term mean monthly data of Ursynów Warsaw Agricultural University meteorological station was used in the analysis: air temperature, maximum and minimum air temperature, amplitude of the temperature, vapor pressure, saturation deficit and relative humidity. Very high values of squared correlation coefficients calculated for two compared methods indicate that both polynomial form of equation and Fouier function may estimate annual course of air temperature and humidity very good. It is noticed that the coefficients for polynomial equations are slightly better than for Fourier functions, particularly for humidity elements.
