METEOROLOGY – ATMOPHERIC PREURE & ALTIMETRY CALCULATOR
Cyclone Central Pressure
A precise tool.
What is the Cyclone Central Pressure & How does it work?
Tropical cyclones are large, swirling storms that form over warm ocean waters. The central pressure of a tropical cyclone is the lowest atmospheric pressure at its eye, and it plays a crucial role in determining the storm’s intensity. Generally, the lower the central pressure, the stronger the cyclone.
P_c = P_s – Delta P
P_c = Central Pressure, P_s = Sea Level Pressure, Delta P = Pressure Difference
The pressure difference (Delta P) between the sea level and the central pressure is a key factor in assessing the cyclone’s strength. This calculator helps estimate the central pressure of a tropical cyclone based on observed data.

Frequently Asked Questions
What is the formula for calculating central pressure in a tropical cyclone?
The formula for central pressure (P_c) is P_c = P_s – ΞP, where P_s is sea level pressure and ΞP is the pressure difference.
How does central pressure relate to the intensity of a tropical cyclone?
Generally, the lower the central pressure, the stronger the tropical cyclone. This is because low pressure indicates more intense storm activity.
What factors can affect the sea level pressure in a tropical cyclone?
Sea level pressure can be affected by various factors such as temperature, humidity, and wind patterns in the surrounding atmosphere.
How do meteorologists use central pressure to predict a cyclone’s intensity?
Meteorologists monitor changes in central pressure over time. A rapid drop in central pressure typically indicates an intensifying cyclone.
What is the typical range of sea level pressure for a tropical cyclone?
Sea level pressure in a tropical cyclone can vary, but it is generally lower than normal atmospheric pressure, often below 980 millibars.
