A dynamic method of air temperature forecast

According to the air temperature change and concerning some information from a region and a large city over the years, this paper delves into a dynamic method of air temperature forecast. A mathematical model and a set of recursive estimate formulas are used for the forecast of air temperature change. By these formulas, the recent information can be fully applied, a forecast with satisfactory accuracy is obtained. The calculation is simplified, and the forecast effect is better than that by ordinary least square estimate method.
