Abstract

This study aims to design an early warning system based on machine learning for short-term prediction of nocturnal frosts in Kurdistan Province in the west of Iran. Four models of artificial neural network (ANN), support vector machine (SVM), adaptive neuro-fuzzy inference system (ANFIS), and multiple linear regression were used to achieve this main goal. Hourly data of six variables of dry-bulb temperature, wet-bulb temperature, cloud cover, relative humidity, and wind speed and direction were selected as the inputs of these four models at 18:30 local time, and according to them, nocturnal temperatures were predicted for 21:30, 00:30, 03:30, and 06:30 local time. Comparing the outputs of these four models with observational data, all models predicted nocturnal temperatures both in the early hours (21:30 and 00:30 local time) and in the late hours of the night (03:30 and 06:30 local time) the same or less than the observational temperatures. Considering the different performance criteria of the models, such as mean absolute errors (MAE), mean squares errors (MSE), and root-mean-squares errors (RMSE), ANN with Posline transfer function, and Trainlm training function, has less error and better performance in predicting nocturnal temperatures compared to other models. When the main goal is predicting the temperature extremes, especially frost, it is concluded that ANN did not perform very well compared to other models. In addition, ANFIS and SVM models have a better performance in this area than other models. Finally, an early warning system for nocturnal frost was designed for Kurdistan Province in the west of Iran using these four models, and its ability was tested to make short-term nocturnal frost predictions. The results show that this system is suitable for the short-term prediction of nocturnal frosts.
