From childhood we are taught about land breeze and sea breeze , but I always had a doubt.
Look at diagram
Book just say " air above ocean become warm so it rise up creating a low pressure zone so air from land that is cool during night and is comparatively higher pressure flow to ocean creating land breeze and cycle continues"
But they never clearly explain what is happening above the land breeze I.e see those two arrows parallel to land and ocean near moon in diagram and 3rd arrow with down head towards land,
So what actually happening there?
Can you please explain me what those three arrows mean actually? ( 2 arrow parallel to land and one arrow pointing on the land) why arrow direction is drawn in such way ?
