了解什么在物理上决定了温度分布的形状，将有助于对全球变暖带来的局部温度进行更可靠的预测。我们推导出温度分布形状与每个温度百分位条件平均温度平流之间的关系。这使得能够量化由于平均温度、水平温度平流和其他过程（例如辐射和对流）的变化而导致的每个百分位数的变化。我们利用这种关系来检查二氧化碳增加的理想化水生行星模型中的全局模型模拟。二氧化碳增加一倍和四倍时分布的变化是显着的，并且它们是由不同的过程引起的。我们发现，除了上、下 10% 的分布外，中纬度地区的温度分布大部分可以用水平平流来解释。
Understanding what physically sets the shape of temperature distributions will enable more robust predictions of local temperature with global warming. We derive the relationship between the temperature distribution shape and the advection of temperature conditionally averaged at each temperature percentile. This enables quantification of the shift of each percentile that is due to changes in the mean temperature, in horizontal temperature advection, and other processes (e.g., radiation and convection). We use this relationship to examine global model simulations in an idealized aquaplanet model with increasing carbon dioxide. Changes in the distribution with doubling and quadrupling of carbon dioxide are significant, and they are caused by different processes. We find that midlatitude temperature distributions can be explained mostly by the horizontal advection, except in the upper and lower 10% of the distribution.
