Warunki termiczne Rolniczej Stacji Doświadczalnej w Zawadach

The aim of the present paper is to analyse thermal conditions at the Zawady Experimental Farm (EF). The work utilises the results of measurements of average 24-hour air temperature from 2002–2006 obtained from an automatic meteorological station (geographical location: Hs – 150 m, φ – 52.06N, λ – 22.56E) situated in the Zawady EF. On the basis of the results of observations an average monthly air temperature as well as average yearly air temperature were calculated, the values and dates of an occurrence of minimum and maximum 24- -hour air temperatures were determined, the length, beginning and end of meteorological growing seasons were determined, and the number of days in the temperature ranges of the winter and summer period were calculated. The average yearly air temperature at the Zawady EF ranged from 7.9oC (2004) to 8.9oC (2002).
