Cyclostrophic Approximation to Wind Speed

Go Cyclostrophic Approximation to Wind Speed = (Scaling Parameter*Parameter Controlling Peakedness*(Ambient Pressure at Periphery of Storm-Central Pressure in Storm)*exp(-Scaling Parameter/Arbitrary Radius^Parameter Controlling Peakedness)/(Density of Air*Arbitrary Radius^Parameter Controlling Peakedness))^0.5

Ambient Pressure at Periphery of Storm

Go 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

Pressure Profile in Hurricane Winds

Go Pressure at Radius = Central Pressure in Storm+(Ambient Pressure at Periphery of Storm-Central Pressure in Storm)*exp(-Scaling Parameter/Arbitrary Radius^Parameter Controlling Peakedness)

Maximum Velocity in Storm

Go Maximum Velocity of Wind = (Parameter Controlling Peakedness/Density of Air*e)^0.5*(Ambient Pressure at Periphery of Storm-Central Pressure in Storm)^0.5

Friction Velocity given Dimensionless Fetch

Go Friction Velocity = sqrt([g]*Straight Line Distance over which Wind Blows/Dimensionless Fetch)

Friction Velocity given Dimensionless Wave Height

Go Friction Velocity = sqrt(([g]*Characteristic Wave Height)/Dimensionless Wave Height)

Wind Speed given Fully Developed Wave Height

Go Wind Speed = sqrt(Fully Developed Wave Height*[g]/Dimensionless Constant)

Dimensionless Fetch given Fetch-limited Dimensionless Wave Height

Go Dimensionless Fetch = (Dimensionless Wave Height/Dimensionless Constant)^(1/Dimensionless Exponent)

Fetch-Limited Dimensionless Wave Height

Go Dimensionless Wave Height = Dimensionless Constant*(Dimensionless Fetch^Dimensionless Exponent)

Dimensionless Fetch

Go Dimensionless Fetch = ([g]*Straight Line Distance over which Wind Blows/Friction Velocity^2)

Frequency of Spectral Peak for Dimensionless Wave Frequency

Go Frequency at Spectral Peak = (Dimensionless Wave Frequency*[g])/Friction Velocity

Friction Velocity for Dimensionless Wave Frequency

Go Friction Velocity = (Dimensionless Wave Frequency*[g])/Frequency at Spectral Peak

Dimensionless Wave Frequency

Go Dimensionless Wave Frequency = (Friction Velocity*Frequency at Spectral Peak)/[g]

Characteristic Wave Height given Dimensionless Wave Height

Go Characteristic Wave Height = (Dimensionless Wave Height*Friction Velocity^2)/[g]

Dimensionless Wave Height

Go Dimensionless Wave Height = ([g]*Characteristic Wave Height)/Friction Velocity^2

Fully Developed Wave Height

Go Fully Developed Wave Height = (Dimensionless Constant*Wind Speed^2)/[g]

Distance from Center of Storm Circulation to Location of Maximum Wind Speed

Go Distance from Center of Storm Circulation = Scaling Parameter^(1/Parameter Controlling Peakedness)

What is an Azimuth?

An Azimuth is an angular measurement in a spherical coordinate system. The vector from an observer to a point of interest is projected perpendicularly onto a reference plane; the angle between the projected vector and a reference vector on the reference plane is called the azimuth.
