Chimney noise in bedroom

[cruz99]

During high winds the chimney makes a howling noise in the bedroom. There is no massive draught from the gas fire downstairs or any noise but it's annoying at night as it is right by my head.

We have a 60's build chalet bungalow where the chimney is narrow on the 1st floor

Could it be the design of the chimney pot/cowl that's causing it?

Ours has vertical vent slots rather like this

where all the pots I see for sale have horizontal vent slots

Yes the problem could be the pots as wind across a slot creates a flute.
I get similar problem with a cars roof bars.
