Yeah Victor Alpha 3, Victor Whiskey X-ray returning. Yeah thanks for the question Ken. Actually I've discussed this a few times before on the Science Night. Yeah the Fujiwara effect, so for what people don't know it's basically it's a it's a form of binary interaction. So you would see this with stars that are orbiting each other and spinning you know and they'll sometimes get closer and closer and sort of collide with each other. So vortices do this all the time. So on Earth here the Fujiwara effect you see this where where vortices essentially become entangled and they'll merge together and become one one vortices. So with tropical storms it's less common it certainly absolutely happens but it's less common with tropical systems because so tropical systems basically draw in moisture in the low levels and they exhale the moisture in the upper levels right so they ventilate themselves at the tropopause which is the top of the troposphere where it meets the stratosphere and and it's dry up there right so so tropical systems are driven by lots of heat energy they basically so the vertical thermal column where the clouds are they try and warm that as much as they can and their energy is derivative from from latent heat release right sensible heat energy and some other things. Anyhow all that stuff aside the so so what I'm getting at here is you have a low pressure you a low pressure system which is what a tropical system is system is but where it starts ventilating itself in the upper levels you have essentially displacement large-scale displacement on a on a synoptic scale so so you're taking air from one part of the atmosphere and moving it to another part of the atmosphere and this finds its way back to the surface as a ridge of high pressures subsidence or subsiding air so air so dry high-level air sinking down to the surface right let me cycle it
