6. Pressure Systems

7. High Pressure system
High-pressure systems are usually associated with fair weather. This is because as the air sinks, it warms and is able to hold more water vapor. Thus, in these systems, clouds tend to evaporate and the air stabilizes. Storms have a hard time forming in stable air
= Clear Sky's and low humidity

8. Low Pressure Systems Usually means cloudy or stormy weather is at hand
A system forms based on the interaction between the atmosphere and large bodies of water.
When low pressure builds over warm water, it may begin to organize and can form a tropical wave, which can turn into a hurricane
