1. Influences on Weather

2. EQ: What is air pressure and how does it effect the weather?

3. Weather is the state of the atmosphere at a particular place and time.
The amount of water in the air, the temperature of the air and the precipitation are all used to describe the atmosphere.

4. Air Pressure Air Pressure is the weight of the air.
Measured with a barometer in millibars.

5. So what about Low Air Pressure??
Low pressure- lousy weather
Low pressure can occur in ANY season
As temperature rises, air becomes less dense creating low pressure
Low pressure = stratus clouds
Low pressure means the air in the atmosphere is more dense (heavy with water vapor/water droplets)

6. What does it look like??
Let’s try a hands-on model

7. What’s the deal with High Air Pressure then?
High air pressure means you are Happy
High air pressure means the air in the atmosphere is more dense
Fair weather
Clear Skies
