Document Summary
Also wind trans ports heat , moisture, dust, bacteria and pollen: wind circulates throughout the atmosphere in different ways. What is it caused by: sea breeze is a local wind system. This difference in isobars causes horizontal pressure gradient force overhead. Further resulting in air to go from high pressure (*warm) to low pressure (cold) (2) how does this movement of air from high to low pressure effect surface. (a) air pressure on surface also changes because of above movement. Because air piles up on north as it moves from (south) warm to cold (north). Thermal pressure circulation is maintained by local surface heating and cooling and thus weakens with height: sea breeze thus is a type or function of thermal circulation. Uneven heating rates of land and sea cause mesoscale coastal wind. During day the land heats faster than the sea, causing thermal low in land and thermal high in sea.
