Spectral Processing

SPECTRAL PROCESSING:

Control spectral processing (A,B): SPCcn

Change horizontal resolution (A,B): SPCINTc

Spectral transformation parameters: SPCMNKc

Define gradient derived fields in spectral space: SPCGRAD

Set range of spectral bandpassing (A,B): SPCBPcn

Fields deleted before return to gridpoint space: SPCDFcn

Fields excluded from spectral processing (A,B): SPCEFcn

Define fields as vector pairs: SPCVP

Control spectral data form: SPCTAVV

SPECTRAL PLOTTING:

Control spectral graphics: SPSNGRF

Control y-interval range on spectral graphs: SPGYINT

SPECTRAL DERIVED FIELDS:

Vector-pair derived fields: SPCVP

Gradient derived fields: SPCGRAD

EXAMPLES:

1. Plot the kinetic energy spectrum.

2. Spectrally truncate a CCM2 T42 to T5.
