What is the main difference between local winds and global winds?
Local winds cover very short distances. Global winds are large air masses that are created mainly as a result of the earth’s rotation, the shape of the earth, and the sun’s heating power.What is worse La Nina or El Nino?
La Niña is also sometimes called El Viejo, anti-El Niño, or simply “a cold event.” La Niña has the opposite effect of El Niño.
