URBAN HEAT ISLAND
Methods
WRF Model
The Weather Research and Forecasting (WRF) Model is a cutting-edge mesoscale numerical weather prediction system used for both research and operational forecasting. Developed since the late 1990s by a collaboration of institutions like NCAR and NOAA, WRF supports simulations across a range of scales and integrates advanced physics, numerics, and data assimilation. It is widely used globally for real-time forecasts and research.
Research 1 - Landcover type
Urban 100
Cropland 100
Water Bodies 100
Mixed Forest 100
We selected urban, cropland, water bodies, and mixed forest as the land use types. Before comparing the model where urban areas are combined with other land use types, we created a "single-use" model where all areas share the same land use type to aid understanding.

To compare each land cover type, a model was used where the urban area was placed in the center, surrounded by cropland, water bodies, and mixed forest. The size of the city center is fixed as 50.

To compare the characteristics of each land cover type according to the distribution of urban areas, we examined cases where the urban area was located in the center and on the sides, respectively. The size of the center area is fixed as 50.
Variables
To study the urban heat island phenomenon in greater detail, we utilized several variables, including temperature with wind vectors, relative humidity, u-wind, and w-wind. We generated vertical contour plots for each variable and conducted a comprehensive analysis.
