Moisture & Temp
Term | Definition |
---|---|
Absolute Humidity | The TOTAL amount of moisture in the air, measured in grams of water vapor per kilogram of air |
Relative Humidity | The percent of moisture in the air compared with how much moisture it can hold |
Wet Bulb | The temperature of the air compared to how much moisture there is |
Dry Bulb | The regular temperature you see all the time |
Saturated | The air is holding as much moisture as it can |
Dew Point | The temperature at which water vapor in the air will condense onto surfaces |
Radiation Cooling | Earth’s Surface absorbs light from the sun throughout the day, heating the Earth and the atmosphere. At night, that heat is radiated from the Earth, which means the Earth loses heat and gets colder. |
Contact Cooling | When air comes into contact with cooler surfaces, it cools |
Adiabatic Cooling | As air rises, it expands. As air expands, air pressure decreases and air temperature also decreases. |
Orographic Lifting | mountains force air upwards, cooling it |
Frontal Wedging | where one air masses pushes another up |
Convection-Convergence | warm air rises as it expands |
