Winds are caused by low and high pressure zones, mainly due to temperature differences of atmospheric air in different regions. Air moves from high to low-pressure zones causing winds.
Local winds, as the name suggests, are winds due to regional temperature differences. An example is sea breeze caused by temperature differences over land and sea in the region.
Global winds, on the other hand, are caused by large pressure systems across the planet. These are mainly caused by differences in how the sunlight ‘hits’ the planet at different latitudes – due to earth’s spherical nature- causing differential heating of the earth. These winds travel great distances causing trade winds.
