R: Coriolis parameter on rotating earth

coriolis {oce} | R Documentation

## Coriolis parameter on rotating earth

### Description

Compute f, the Coriolis parameter as a function of latitude (see reference 1), assuming earth siderial angular rotation rate omega=7292115e-11 rad/s. See reference 1 for general notes, and see reference 2 for comments on temporal variations of omega.

### Usage

    coriolis(latitude, degrees = TRUE)

### Arguments

`latitude` | Vector of latitudes in degN or radians north of the equator.
`degrees` | Flag indicating whether degrees are used for latitude; if set to `FALSE`, radians are used.

### Value

Coriolis parameter, in radian/s.
