This is a lesson about humidity.


In which phases can water be seen by the un-aided human eye?


Which value is more important to meteorologists?


What condition enables air to hold more water vapor?
Hint: What promotes drying?

When is the relative humidity usually the highest?

Determine if the change will increase the amount of moisture and relative humidity or if the change will decrease the amount of moisture and relative humidity.
Air blows across the Great Lakes
Air warms as the sun shines
Air falls down into the Grand Canyon
Air rises as it flows up the side of a mountain
Water evaporates from the ocean
Air blows across a desert
Factors that increase relative humidity
Factors that decrease relative humidity

The only time air reaches its dew point is when temperatures drop overnight.

Consider heating a pan of food using a stovetop.
When the food is simmering, steam is visible. When a lid is placed over the pan, droplets of water collect on the cover.
Explain how the apearance of water droplets on the lid relates to dew point. A comparison of temperatures must be included in your description.
