Seasonal dummy variables are introduced to portray the fluctuating tendency of seasonal series. The parameter estimation method for the new model is discussed, and the Differential Evolutionary algorithm is used to solve the linear and hyper-parameters of the model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>The DS-DVGM(1,1,T) model outperforms other forecasting models, accurately describing the seasonal pattern of soil moisture in six cities of Henan Province, with forecast results closely matching actual drought conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Practical implications<\/jats:title>\n                    <jats:p>The DS-DVGM(1,1,T) model provides a reliable forecasting benchmark for agricultural drought monitoring.
