R: Check Linear Atmosphere

CheckAtm.lin

R Documentation

Check Linear Atmosphere

Description

Verifies that an atmosphere contains all required elements and fills in missing elements with default values.

Usage

CheckAtm.lin(ATM = list())

Arguments

ATM

List that may include characteristics of an atmosphere

Details

A linear atmosphere variable must contain the elements described in the "Value" section. Default values for these are as follows: z0: 0 c0: 330 wx0: 0 wy0: 0 rho0: 1.2929 * exp(-ATM$z0/6800) gc: -10^9 gwx: 0 gwy: 0 grho: -0.0001901058 * exp(-ATM$z0/6800)

Other functions may encounter problems when working with an effective sound speed gradient of zero.

Value

List including the following elements:

`z0`	Elevation of intercept layer (m)
`c0`	Intrinsic sound speed at intercept layer (m/s)
`wx0`	Zonal (east-west) wind at intercept layer (m/s)
`wy0`	Meridional (north-south) wind at intercept layer (m/s)
`rho0`	Density at intercept layer (kg/m^3)
`gc`	Vertical intrinsic sound speed gradient (1/s)
`gwx`	Vertical zonal wind gradient (1/s)
`gwy`	Vertical meridional wind gradient (1/s)
`grho`	Vertical density gradient (kg/m^4)

Examples

# quickly make a new default atmosphere
ATM = CheckAtm.lin()

# fill in missing values for an existing atmosphere
ATM = list(c0 = 343, gc = -0.006)
ATM = CheckAtm.lin(ATM)
