Ambient Pressure at Periphery of Storm Formula

Is a Hurricane High or Low Pressure?

Hurricanes are powerhouse weather events that suck heat from tropical waters to fuel their fury. These violent storms form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.

How to Calculate Ambient Pressure at Periphery of Storm?

Ambient Pressure at Periphery of Storm calculator uses Ambient Pressure at Periphery of Storm = ((Pressure at Radius-Central Pressure in Storm)/exp(-Scaling Parameter/Arbitrary Radius^Parameter Controlling Peakedness))+Central Pressure in Storm to calculate the Ambient Pressure at Periphery of Storm, The Ambient Pressure at Periphery of Storm formula is defined as the pressure profile, which is when a tropical cyclone reaches hurricane strength, its low-pressure centre is called the “eye” of the storm. The lower the barometric pressure at the centre of the storm, the stronger the hurricane, and vice versa. Ambient Pressure at Periphery of Storm is denoted by p_n symbol.

How to calculate Ambient Pressure at Periphery of Storm using this online calculator? To use this online calculator for Ambient Pressure at Periphery of Storm, enter Pressure at Radius (p), Central Pressure in Storm (p_c), Scaling Parameter (A), Arbitrary Radius (r) & Parameter Controlling Peakedness (B) and hit the calculate button.
