Sea/Land breeze circulation - afternoon, cont.

Q: what is the resultant air flow?

  • onshore flow at low levels - sea breeze

  • offshore flow at upper levels - return flow

  • rising air over land - due to convection and lifting over the sea-breeze front

  • sinking motion over the ocean

  • NOTE: the surface low pressure over land is often referred to as a warm core thermal low 

  • so, what is this sea-breeze front ???
