Idealized numerical simulations of a land/sea breeze

Presentation

• Presentation for METR 6223, Advanced Mesoscale Meteorology, Fall 2008
• This was taken from one of my graduate school courses. Please excuse any writing mistakes.

Model Settings

• WRF v3.0.1
• Two dimensional (x-z)
• 400 km x 20 km
• 24 hours, from 06 UTC to 06 UTC
• No coriolis
• WRF single moment 3-class microphysics scheme, Dudhia and RRTM radiation schemes, Noah land-surface model, MM5/YSU surface-layer/PBL combination for vertical diffusion, and a two-dimensional Smagorinsky closure for horizontal diffusion.
• Initially, the ocean surface temperature was +7K larger than that of the land surface temperature.
• Varied grid spacing and horizontal extent of land

• LSB2-040: DX = 2 km, Land Extent = 40 km
• LSB1-100: DX = 1 km, Land Extent = 100 km
• LSB500-100: DX = 500 m, Land Extent = 100 km
