Development of the New Method for Frost Detection in Croatia

he rise in temperature in recent years has significantly affected the entire biosphere, including the beginning and duration of the growing season. The earlier start of the growing season is visible in many crops and trees. Although an increase is generally visible in all temperatures (minimum, maximum, and mean daily), this does not exclude the occurrence of extreme weather conditions that can damage crops. In particular, a special danger is related to frost. Since there is no unequivocal method for determination of the occurrence of a frost event, many studies try to determine the risk of its occurrence using different criteria. This study aimed to determine the best method for predicting the frost event in the study area. In that matter, several already introduced methods, were tested on data and observations from meteorological stations all over Croatia. Also, a new approach has been tested, in which frost day is described with the criterion: T min < 3 °C and dew point temperature (calculated using the minimum temperature) T d < 0 °C. It was this method that showed the best results. The probability of detection for this method is higher than 90%, and the probability of false detection was around 15%. Also, all methods were subjected to the Signal Detection Theory. The new approach showed the best results again with a high accuracy index and not showing bias to over or under predicting. Considering all that, this new approach to frost prediction has proven to be very good and provides the possibility provides the ability to predict frost in the future as well as forecast frost a few days ahead which can be significant for the protection of crops.
