According to the 2007 IPCC Report during the last decades an extensive reduction in the number of frost days has been observed mainly in the mid-latitude regions. Furthermore, the dynamical projections from several models estimate an additional decrease of the frost days all over Europe and especially in the Mediterranean region until the end of the twenty-first century. Thus, the main score of the present study is the statistical analysis of the frost characteristics in the Greek region. Maximum and minimum temperature daily data will be utilized for 21 meteorological stations uniformly distributed over the domain of study and the analysis of the number of frost days and the length of the frost-free period will take place. Finally, using the future projections of updated regional climate models, developed under the frame of the ENSEMBLES project, we will estimate the future changes of the aforementioned parameters due to the enhancement of the greenhouse effect.
