Planetary winds are the winds which blow only in one direction over a vast area. Examples: Westerlies, Trades, etc.
Periodic winds are the winds which blow at regular intervals of time. Examples: Land and Sea Breezes.
Local winds are the winds which blow over a small area for a short intervals of time. Examples: Loo in India, Chinook in North America.

PERIODIC WINDS:- Periodic winds blow at regular intervals or in regular cycles. They are winds that result from localised differences in pressure and temperature. For example, land and sea breezes and the seasonal wands. LOCAL WINDS:- Local winds are restricted to a certain place only.
