Influence of Meteorological Parameters on the Urban Heat Island in Moscow

The urban heat island (UHI) intensity in Moscow and the influence of various meteorological parameters are discussed using weather station data. maximal average in-space UHI intensities, i.e., a comparison air temperature T either city centre or whole area together with rural zone have averaged 1.9 0.9 °C, respectively, recent years. has stabilized over past decade is not growing. Under conditions strong anticyclone, space time reaches 11–12 °C. Low cloudiness amplitudes diurnal temperature, as well surface demonstrate closest relationship among other correlation coefficient up to −0.67 for low intensity. effect wind speed, total relative humidity on slightly weaker, but still significant. relationships all closer than those one. multiple between both (low daily speed) 0.76–0.82. function minimum range from −4 0 °C; its growth at lower higher due anticyclonic weather. speed decreases strength. threshold value which this asymptotically approaches limit 10 m/s 40–200 m layer. functions decrease increasing differences them significant if cloud cover more 50%.
