Question

When checking the weather what does the pressure tell you?

In: 503

Answer 1

High pressure == stable. Low pressure == unstable. When it’s very high pressure, expect a beautiful sunny day. Very low pressure, expect bad weather. Lowest in the center of hurricanes. Now here’s the thing…. high pressure wants to fill low pressure to equalize pressure. This causes winds to move. The rotation of hi vs lo pressure systems are opposite- so the winds from each affect neighboring weather patterns. That’s how they forecast the direction of weather systems.
