	procedure mjo_phase_background (

		opt [1] : logical   



An NCL Workstation identifier. The identifier is one returned either from calling gsn_open_wks or calling create to create a Workstation object.


If opt=False, the function will operate under default mode regardless of any attributes associated with the variable.

If opt=True, then the following attributes, associated with opt, may be used to alter the default behavior.

opt@tiMainString: If present, this specifies the title associated with the background plot.
opt@radius - If opt=True and this attribute is present, then this attribute will specify the radius of the inner circle.
