Why is wind speed important in atmospheric science? How does wind shear affect thunderstorms? How does climate change affect wind? How is wind involved in the water cycle? How does evaporation affect heating and cooling? How do jet streams affect air masses? How does salt affect evaporation? H...
the normal air pressure at a given elevation (seeHow Hot Air Balloons Workto learn more about air temperature and pressure). When that lighter hot air suddenly rises, cooler air flows quickly in to fill the gap the hot air leaves behind. That air rushing in to fill the gap is wind. ...
