Extreme weather events inWest Hungary

Agricultural production is a rather risky activity, as it is largely exposed to extreme weather events. This paper focuses on the frost and hail data in springtime, affecting fruit production in West Hungary. Regarding absolute minimum temperatures in April, significant increase of the standard deviations could be observed. Among the sites examined Nagykanizsa shows the highest risk values. According to our evaluation Nagykanizsa is not recommended to plant sour cherry, sweet cherry and apricot orchards because in some years spring frost will occur. If the plantation is in Zalaegerszeg, Szombathely, Gyôr or Keszthely than usage of frost prevention system is recommended. Siófok is the only area to grow apricot with good result
