What is WRF?
The Weather Research and Forecasting (WRF) Model is a state of the art mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications. It features two dynamical cores, a data assimilation system, and a software architecture supporting parallel computation and system extensibility. The model serves a wide range of meteorological applications across scales from tens of meters to thousands of kilometers.
Research Theme 1
Mixed Forest vs. Water Bodies
To compare the case of forest and water, we use the land use index of ‘Mixed Forest’ and ‘Water Bodies’. The size of urban areas, whose land use index is ‘Urban and Built-Up Land’, is fixed as 50.

Urban at Center vs. Deciduous Broadleaf Forest at Center
To compare the case of urban-centered and forest-centered, we use the land use index of ‘Urban and Built-Up Land’ and ‘Deciduous Broadleaf Forest’. The size of the city center is fixed as 50.

Size of urban: 20 vs. 60
To see the difference between a large forest case and a small forest case, we differentiate the size of the urban as 20 and 60. The land use indexes are fixed as ‘Urban and Built-Up Land’ and ‘Deciduous Broadleaf Forest’.

Types of Forest
To compare the case of each forest, we use the land use index of ‘Deciduous Broadleaf Forest’, ‘Deciduous Needleleaf Forest’, ‘Evergreen Broadleaf Forest’ and ‘Evergreen Needleleaf Forest’. And the size of urban areas, whose land use index is ‘High Intensity Residential’, is fixed as 50.

Variables and Plots
To see how the urban heat island phenomenon changes, we use specific variables. We draw the vertical contour plots of temperature, relative humidity, u-wind, and w-wind, and also the wind vector plots.
