I’ve read that predicative complement “can have the form of an AdjP or of a bare role NP (a count singular with no determiner, such as President of the Republic, treasurer, etc.) - CGEL,p.253”. Is it an option to put an indefinite article in front of meteorologist? (I don’t decide whether he pronounces ‘a’.)

Answer

No, use of the indefinite article with a professional title is generally incorrect in standard English. More particularly, it is incorrect when using it as a title:

Incorrect: He is a CIO Smith.

Incorrect: I am an exterminator Jones.

There is one exception: If the speaker intends humourous effect, this construction can be used. It basically says "Yup, that's me, that's what I am. Hahaha." However, it is non-standard.

It is correct to use the indefinite article when the title is used as an occupation:

Correct: I am a CIO, and my name is Smith.

Correct: He's an exterminator. His name is Jones.

Other than occupational or humourous usage, do not use an article:

Correct: He is President Smith.

Correct: I'm meteorologist Eric Burris.

At its simplest, a title works like this:

Is it being used as a title? Don't use an article.

Is it being used to describe an occupation? Use an article.
