The urban heat island effect is a phenomenon in which the city is significantly warmer than the surrounding rural areas.

 
The larger the city size, the greater the maximum surface temperature deviation and the weaker U wind.

As with changes in city size, the increase in atmospheric temperature affects the variables with the same tendency.
 

In the ideal case simulation through WRF, reality such as snow and heating effects are not included, so the cooling difference between asphalt and mixed forest seems to be noticeable in the lower temperature case.
 

We can observe the dome-shaped pattern through the W wind graph in default case simulation results. 
 

In conclusion, an increase in city size due to urban development could intensify the heat island effect, and the increase in atmospheric temperature due to weather and climate change can amplify the urban heat island effect.
