In this term project, we wanted to find out the rate of temperature variation according to initial temperature setting.

So we modeled different cases by changing initial temperature.

And also by changing geographical surrounding and land use type in each case, we could have conclude the result like this.

The variable we have changed was 'initial temperature of the land surface'.

Therefore, "as time goes by, starting from the same temperature at T2m at first, temperature variation(difference) happened being affected by initial surface temperature that we've set."

That is, in early stage of model, similar phase of temperature change which is irrelevant to initial condition can happen.

Also that is not to say that it is not affected by initial temperature at all but is affected a little bit so that some difference can be seen and this difference gradually becomes bigger.

To check 'for which case is it affected a lot', we have changed urban composition using different land use type, we've compared 

 1. 40km, 60km and extremely 200km of grass in urban composition.

 2. 40km, 60km and extremely 200km of water bodies in urban composition.

Before modeling, we expected that there would be some linear or exponential relationship between initial temperature and intensity of UHI, but the result showed that there are no change in temperature due to the change in initial temperature.

In advanced research about UHI, intensity of UHI was seasonally different resulting bigger intensity in winter which is not because of initial temperature but because of difference in heating time by length of day and night.

Therefore, if the heating time is same in the cases of different season then intensity of UHI is same despite the initial temperature.

To conclude, 

In every case, which includes the change in urban composition, initial temperature change does not affect the temperature variation in each case.​
