In dankelley/oce: Analysis of Oceanographic Data

Coriolis Parameter on the 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 ^\circN 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.
