All done, except for 41 across. I have an answer for 38 down which seems to work, but it produces a non-word at 41 across. Any hints would be appreciated.
Thank you drxx and malone, Got it now - after spending, nay, wasting so much time messing about with winds from Siberia and the Arctic. Which now begs the question of where the two-lettered cell is. I was hoping for an early night!!
Thank you Son1ofRover1 and yet again Jack. All done now. I was looking for the moving rather than the static possession and I kicked myself when I saw the posture.
