Abstract: To improve the meteorological service for agricultural facilities and reduce the losses resulting from meteorological disasters, the maximum and minimum temperature forecast models were establish through analysis on factors affecting temperature change inside the sunlight greenhouse and using meteorological observations data from inside and outside the sunlight greenhouse. The model takes weather type and season into consideration, hence saving the trouble of establishing models separately according to different weather type and season. The forecast model is easy to use and has clear physical meaning, and it also passed statistical tests with good regression fitting and high forecast accuracy. It can meet the needs of practical use and can be applied to weather forecasting service in disaster prevention, reduction and relief.

Key words: sunlight greenhouse, maximum temperature, minimum temperature, forecast model
