Abstract: In the report， combined with the ConvLSTM network， the China Meteorological Administration's land surface data assimilation system real-time product dataset （CLDAS） was used to propose a new grid temperature short-term forecast method for the Hainan Island area. With the simulation experiment， a one-hour resolution short-term forecast of the grid temperature in Hainan Island was achieved， in which the grid error of the 12-hour continuous forecast exceeds 2 ℃ at a rate of about 11.5%. The results verified the possibility of applying the model proposed in this study to short-term grid temperature prediction.
