Detailed Description

Physics calculations with defined constants

This class contains various physics calculations, implemented as class
methods, which use defined physical constants. It can be subclassed with
different constants to suit processing of data related to models with
constants defined otherwise.

Member Function Documentation

barom_lapse0_gp()

def palmmeteo.library.PalmPhysics.barom_lapse0_gp	(		cls,
			gp0,
			p,
			p0,
			t0
	)

Converts geopotential based on pressure using barometric equation

barom_lapse0_pres()

def palmmeteo.library.PalmPhysics.barom_lapse0_pres	(		cls,
			p0,
			gp,
			gp0,
			t0
	)

Converts pressure based on geopotential using barometric equation

barom_ptn_pres()

def palmmeteo.library.PalmPhysics.barom_ptn_pres	(		cls,
			p0,
			z,
			t0
	)

PALM's barometric_formula( z, t_0, p_0 )

The calculation is based on the assumption of a polytropic atmosphere
and neutral stratification, where the temperature lapse rate is g/cp.

exner()

def palmmeteo.library.PalmPhysics.exner	(		cls,
			p
	)

Exner function

exner_inv()

def palmmeteo.library.PalmPhysics.exner_inv	(		cls,
			p
	)

Reciprocal of the Exner function

rho_air_ideal_gas()

def palmmeteo.library.PalmPhysics.rho_air_ideal_gas	(		cls,
			p,
			pt
	)

Air density according to ideal gas law from PALM's function
ideal_gas_law_rho_pt( p, t )
