Those surface winds - easterly TEMPO northerly?
Never seen such weirdness the nine years I worked at airfields.
Must be very tricky to handle.
Looking at the METARs for the time of the accident:
OMDB 031000Z 11018KT 5000 BLDU NSC 49/05 Q0993 WS ALL RWY TEMPO 35015KT 1500
OMDB 031048Z VRB06KT 6000 NSC 41/24 Q0992 WS ALL RWY TEMPO 35015KT 3000 DU
It is reminiscent of a sea breeze or sea air incursion, with the lowering of temperature and increase in dew point. Happens quite a bit at airfields that get coastal influences.
If it was a different airmass moving inland, you can get odd effects during the transition, like tailwinds on both ends of the runway. I guess it would pick up a fair bit of dust as well as the TEMPO 1500 alludes.
