What the H is happing with my stove?

The wind has been horrible this winter and this has happened at least three times this winter for the first time ever .As some
backgrown on my set up I have a Napolean 1400 pedastal I have been a wood burner for around 15 years
with this current set up it comes out the stove and 45 degrees out to thimble then out and stainless triple wall
out side the house and is about leval with top of the roof.Well this wind has been blowing hard and I can listen
when it gustes and it will put out my fire and I mean a good oak fire then puff it come back on blazing well its making
every thing in my house smell like smoke it blowing back through the door seal and somewhere else in the stove.I know
I need a door seal but how do I preavent this? Add more stack its blowing right back down.

Im in NW Ohio and every time its happened it been 50 plus winds also my oak is
two years seasoned and my pipe baffel is open as is my air control I have to keep door closed but still
puffing only way to get it to quit was to go out and take off the clean out on my thimble and smoke come billowing out
of the cleanout ..

Is it possible I need another piece of cimney I about a foot under roof peak?
