Atmospheric Moisture & Fog | Weather & Climate with Prof. Jeremy Patrich

This video introduces the basics of atmospheric moisture, humidity and fog. Water can exist as a solid, liquid, or gas at typical conditions found on Earth. As we learned, the process of liquid water becoming water vapor is called evaporation and this process absorbs or requires energy. The opposite process is called condensation, where water vapor becomes liquid water, releasing energy. Condensation is especially important in atmospheric science because this is the process that allows clouds to form. Before we can understand clouds in the atmosphere, we need to explore concepts like how humidity is defined and what saturation means. In general, humidity is the amount of water vapor in the air. You’ve likely heard of relative humidity and dew point temperature, but what do these quantities mean physically? Need additional support with the lapse rate?
