|---|---|---|
| 1. | Planetary winds blow constantly in a particular direction throughout the year. | Periodic winds blow in a definite direction during a particular period of the day or year. |
| 2. | Planetary winds originate due to the presence of permanent high pressure and low pressure belts on the earth's surface. | Periodic winds are caused due to unequal heating and cooling of the earth's surface. |
