Anemometric conditions in the area of Bydgoszcz in the years 1971-2010 using the example of the Bydgoszcz-Airport weather station

Abstract

This paper refers to the characteristics of anemometric conditions in the area of Bydgoszcz based on data sourced from the Bydgoszcz-Airport weather station in 1971–2010. Annual mean wind speed measured in a multi-annual period was higher in the winter half-year and lower in the summer half-year, which is typical of the climate of central Poland. In the analysed multi-annual period, the annual mean wind speed was 3.3 m·s-1. The annual curve of average wind directions in the multi-annual period was characterised by a prevailing share of west wind, followed by that of south, east and north winds. The prevailing average wind direction in the analysed multi-annual period was west wind (W), followed by southwest (SW), northwest (NW), southeast (SE), east (E), south (S), north (N) and northeast (NE) wind.
