At intermediate altitudes, the air still contains approximately 20.9% oxygen, but the barometric pressure and thus the partial pressure of oxygen is reduced.
The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts.
When the storm made landfall, the barometric pressure fell to 28.81 inches (968 mbar), breaking a previous record set in 1910.
The central barometric pressure continued to fall despite the fact that the storm was beginning to weaken.
As the bar passes overhead, barometric pressure at the observer's location falls steadily.
No barometric pressure was recorded at the time of peak intensity since it occurred over water and away from any ships.
The barometric pressure fell to 999 mb, with sustained winds of 60 mph (95 km/h).
One does not break the barrier of 331½ metres per second at 176 centimetres of barometric pressure.
