Narrative:
Landing runway 5; windshear reports ahead of us -- 10 KTS increase on final. Wind reported 330 degrees/10 KTS; gusts 18 KTS; then 310 degrees/8 KTS. Asked for wind check; 1 mi final. Wind 280 degrees/12 KTS. Went around; requested runway 23. Then wind changed to 310 degrees to 330 degrees at 8 KTS. We landed runway 31. Tower should announce wind whenever shifts to tailwind more than 8-10 KTS. Many jets maximum tailwind is 10 KTS. If we hadn't asked; they may not have announced tailwind.

Title: WESTWIND FLT CREW ARRIVING IN CONDITIONS INCLUDING WINDSHEAR AND VARIABLE WINDS NOTES THAT UNTIL ASKED; THE TWR DID NOT BROADCAST WIND CONDITIONS THAT HAD SHIFTED TO A TAILWIND EXCEEDING HIS ACFT LIMITS.
Narrative: LNDG RWY 5; WINDSHEAR RPTS AHEAD OF US -- 10 KTS INCREASE ON FINAL. WIND RPTED 330 DEGS/10 KTS; GUSTS 18 KTS; THEN 310 DEGS/8 KTS. ASKED FOR WIND CHK; 1 MI FINAL. WIND 280 DEGS/12 KTS. WENT AROUND; REQUESTED RWY 23. THEN WIND CHANGED TO 310 DEGS TO 330 DEGS AT 8 KTS. WE LANDED RWY 31. TWR SHOULD ANNOUNCE WIND WHENEVER SHIFTS TO TAILWIND MORE THAN 8-10 KTS. MANY JETS MAX TAILWIND IS 10 KTS. IF WE HADN'T ASKED; THEY MAY NOT HAVE ANNOUNCED TAILWIND.
