In Context
Hectopascal (hPa) is one of 10 terms classified under Atmospheric Measurements in the azifind.com Typhoon Wiki. Understanding where a term sits within its category clarifies how it relates to the stages, warnings, or hazards around it during an active tropical cyclone.

Air Pressure
Air pressure is another term for atmospheric pressure, the force exerted by the weight of the atmosphere at a given location.
Atmospheric Pressure
Atmospheric pressure is the weight of the air pressing down on a given point, and a tropical cyclone's central pressure is one of the key figures used to estimate its intensity.
Barometric Pressure
Barometric pressure is atmospheric pressure as measured by a barometer, the standard instrument used to track pressure changes as a storm approaches.
Dew Point
Dew point is the temperature at which air becomes saturated with moisture and condensation begins to form, a more consistent measure of humidity than relative humidity alone.
Humidity
Humidity is the amount of water vapor present in the air, a key ingredient that fuels the thunderstorm activity within a tropical cyclone.
Millibar
A millibar is a unit of atmospheric pressure, numerically equal to a hectopascal, historically used before hPa became the standard meteorological unit.
Relative Humidity
Relative humidity is the amount of water vapor in the air expressed as a percentage of the maximum the air could hold at that temperature.
Temperature
Temperature measures how warm or cool the air is, and sea surface temperature specifically is one of the main factors determining whether a tropical cyclone can form or intensify.
