TTheta2P: Pressure from temperature and potential temperature

In aiRthermo: Atmospheric Thermodynamics and Visualization

Pressure from temperature and potential temperature

Description

This function calculates the pressure from given potential temperature and temperature, assuming a dry adiabatic evolution (mixing ratio is only used to correct the values of c_p).

Usage

TTheta2P(Temp, Theta, w = 0, consts = export_constants())

Arguments

Temp	A vector with temperature values in Kelvin.
Theta	A vector with potential temperature values in Kelvin.
w	Initial value of mixing ratio (kg/kg). By default 0.
consts	The constants defined in aiRthermoConstants data are necessary.

Value

This function returns a vector with pressure values.

Examples

	data(RadiosondeD)
dPs<-RadiosondeD[,1]*100
dTs<-C2K(RadiosondeD[,3])
dws<-RadiosondeD[,6]/1000
dTds<-w2Td(dPs,dws)
dThetas<-PT2Theta(dPs,dTs)
TTheta2P(dTs,dThetas)
