In the same urban composition (0-199 : grass extremely) with the initial temperature as the only variable, min and max temperature is almost constant, on average 26.0881℃ and 36.1222℃, so that temperature difference of max and min temperature is almost same, on average 10.0341℃.

In the same urban composition (0-199 : water extremely) with the initial temperature as the only variable, min and max temperature is almost same in each initial temperature(280K, 290K, 300K). It is because that water temperature does not change a lot due to large heat capacity.

In timeseries of Case3(extremely all the 200km is grass or water in urban composition) above, we've found that temperature change phase is almost same with different setting of initial temperature.

Therefore, we could also find out that cross-section plots of x-direction wind and temperature is almost same with different initial temperature in extreme case of 200km grass or water in urban structure.

This is the image of cross-section plots of 07UTC, when the x-direction wind is maximum. It shows that in each urban composition, the only variable, initial temperature, doesn't affect the x-direction wind phase and temperature at each height once again.
