9. Local Variations – Land Breezes
Weaker & less common than sea breezes
Dependant on local topography

10. Anabatic Winds
An anabatic wind is a wind which blows up a steep slope or mountain-side during the day, driven by sunshine heating the slope. A hill or mountain-top is warmed by the sun, which in turn heats the air just above it. This air becomes relatively warmer and lighter than other air at a similar altitude over an adjacent valley which does not get warmed as much because of the greater distance to the ground below it and / or if it is in shade. This warmer, lighter air will rise through convection, creating a lower-pressure region into which the higher-pressure air at the bottom of the slope gets drawn, causing the wind.

11. Katabatic Winds
Opposite of Anabatic Wind, downslope movement as air cools.
Can form fog or mist at bottom of slope in valley
