When I did a short 6 week spell as Sqn Ldr (Air) at HQ FIAW Fuerza Area Malvinas in late 2000, a team of met scientists turned up and set up shop in our building. They were researching the danger posed by rotor streaming under certain conditions when the surface wind might seem benign, whereas the wind at 200ft was totally different. They told me that they'd never seen such weird conditions before.
MPA had some VERY challenging wind conditions at times - but closing the airfield seems OTT. State the conditions and allow the operators to assess the threat and mitigate as required.
I would have been entirely happy to land a VC10 on the short RW rather than fight vile crosswinds on the main. Not an option available to a Voyager, I guess? Although it was great fun practising short RW approaches on Saturday mornings when the pongo officers were sleeping off their overindulgence in the DeathStar instead of being at work.
