用随机漫步拟合1901年至1998年44个贝塔世界城市的气温变化

Fitting Temperature Change in 44 Beta World Cities from 1901 to 1998 Using Random Walk

为了进一步证实随机漫步模型能够拟合气温的变化,获得坚实的科学结论,继续利用随机漫步模型拟合44个贝塔级世界城市1901年至1998年的气温漫步和记录气温,得到了很好的拟合效果。拟合结果与我们以前的研究结果相一致。随机漫步模型可以用于描述城市的气温变化。

The random walk model was further used to fit the temperatures of 44 beta world cities from 1901 to 1998, in order to verify that this model can fit temperature change. The results showed that this model can fit both temperature walk and recorded temperature of these cities, which are consistent with our previous results,indicating that the random walk model can be used to describe the temperature change in cities.
