Degree Days in the Croatian Lowlands

Time series of degree days for the different temperature thresholds from stations in the Croatia lowlands have been analysed. The temperature differences, between mean temperatures and temperatures thresholds, are called degree days or temperature sums. Different types of degree days, coolling and heating ones, for the period 1961-1990 have been calculated. The range of the mean annual cooling degree days (CDD<0 C) was from -170 C to -150 C and for the heating (HDD>0 C) was from 3950 C to 4200 C. The results of linear trend analysis and the Mann-Kendall test are shown that the annual degree days of the lowland stations do not significant increase or degrease chronologically.
