How does pressure affect the weather in New Orleans?
Barometric pressure is a key indicator of weather changes. Normal pressure (29.80-30.20 inHg) suggests typical weather patterns for New Orleans with moderate conditions.
Why does barometric pressure change?
Barometric pressure changes due to the movement of air masses, weather systems, and temperature variations. High pressure systems bring sinking air and clear weather, while low pressure systems involve rising air and often bring clouds and precipitation. These systems constantly move across New Orleans, causing pressure fluctuations.
Can barometric pressure affect my health?
Yes, many people are sensitive to barometric pressure changes. Common effects include headaches, joint pain, sinus pressure, and changes in mood. Those with arthritis, migraines, or other chronic conditions may notice symptoms worsen with rapid pressure changes. Today's stable pressure conditions are less likely to trigger these symptoms.
What's the difference between inHg and millibars?
Both measure atmospheric pressure but use different scales. Inches of mercury (inHg) is commonly used in the United States, while millibars (mb) are used internationally. Today's New Orleans reading of 29.87 inHg equals 1,012 mb. Standard sea level pressure is 29.92 inHg or 1,013.25 mb.
