The document summarizes wind formation and wind systems. Winds form due to differences in air temperature caused by uneven solar heating between the equator and poles. The Coriolis effect causes winds to deflect to the right in the Northern Hemisphere and left in the Southern Hemisphere. Major wind systems include trade winds near the equator, prevailing westerlies at 30-60 degrees latitude, and polar easterlies near the poles. Jet streams are high-altitude winds that blow west to east and influence air travel. Local winds include sea breezes that blow inland during the day and land breezes that blow seaward at night due to differences in land and ocean temperatures.
