Abstract
  This study aims to model dust storms in Khuzestan province using hybrid Jenkins-Catalyst SARIMA-ACOR and SARIMA-PSO models. For this purpose, hourly dust data and codes from the World Meteorological Organization (WMO) were used from seven synoptic stations across Khuzestan over a 40-year period. To enhance ...  Read More

Abstract
  Drought is random and nonlinear phenomenon and using linear stochastic models, nonlinear artificial neural network and hybrid models is advantaged for drought forecasting. This paper presents the performances of autoregressive integrated moving average (ARIMA), Direct multi-step neural network (DMSNN), ...  Read More
