• Rd is the specific gas constant for dry air (287.058 J/(kg K)).
• g is the gravitational acceleration (9.81 m/s²)

This functions was introduced in version 5.10.0.

list of numbers xy_from_polar(magnitude: number,  dir: number)

list of vectors xy_from_polar(magnitude: vector,  dir: vector)

fieldset xy_from_polar(sp: fieldset, dir: fieldset)

Converts vector data from meteorological polar representation to xy representation. In polar representation the data is specified by two components:

• magnitude: represents the speed/magnitude
• dir: represents the direction of the vector in degrees. Angles measured from South in clockwise direction.

In the target xy representation the x axis points East while the y axis points North.

The type of the result depends on the type of the input data

• if the input is number the result is a list of two numbers
• if the input is vector the result is a list of two vectors, the first vector contains the x components while the second vector the y components
• if the input is fieldset the result is a fieldset where an x component field is immediately followed by the corresponding y component field.

This function was introduced in version 5.10.0.
