It is found that the improved nine level model has a better simulations of the geopotentialfield, the temperature field and the precipitation field in winter and summer.
对比检验表明，改进后的九层模式对高度场、温度场及降水场的模拟均要优于原五层模式。

On the basis of the research into the bulk temperature field in gears makes research theoretically on the source temperature field in gears, which is a typical geopotential problem.
