Sea/Land breeze circulation - afternoon

  • by afternoon (3 PM), the land is much warmer than the ocean surface

  • the air over the land will be warmer - will have expanded in response the the surface heating

  • hence, at low levels, have cold column of air over the ocean, warm column of air over the land

  • this differential heating generates the pressure distribution to the right -->>

  • Q: what is the resultant air flow?
