Description

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

Usage

1
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
