Narrative:

After a lengthy ground delay we were cleared onto runway. ATC was planning 10 mi spacing. Wind was pretty steady 330-340 degrees at 18-20 KTS. Cleared for takeoff and we encountered severe windshear on takeoff. During latter part of recovery, I called dfw tower and told them of our encounter with severe windshear and added that they should stop departures. The female controller snapped back something like, 'you can't stop the departures, they are going off one at a time 10 mi apart!' I again told her we had encountered severe windshear and she should be aware and halt departures. She handed us off to departure control. I told this controller same thing and he said he was going to notify his supervisor to relay our report. We had firewalled the engines and after talking to tul maintenance, diverted to tul. Supplemental information from acn 333079: the problem being reported here is very simple and direct -- the tower ignored our experience. They are so accustomed to routine LLWS warnings that they do not understand the severity of an encounter that would compel a captain to say, 'stop all departures!'

Narrative: AFTER A LENGTHY GND DELAY WE WERE CLRED ONTO RWY. ATC WAS PLANNING 10 MI SPACING. WIND WAS PRETTY STEADY 330-340 DEGS AT 18-20 KTS. CLRED FOR TKOF AND WE ENCOUNTERED SEVERE WINDSHEAR ON TKOF. DURING LATTER PART OF RECOVERY, I CALLED DFW TWR AND TOLD THEM OF OUR ENCOUNTER WITH SEVERE WINDSHEAR AND ADDED THAT THEY SHOULD STOP DEPS. THE FEMALE CTLR SNAPPED BACK SOMETHING LIKE, 'YOU CAN'T STOP THE DEPS, THEY ARE GOING OFF ONE AT A TIME 10 MI APART!' I AGAIN TOLD HER WE HAD ENCOUNTERED SEVERE WINDSHEAR AND SHE SHOULD BE AWARE AND HALT DEPS. SHE HANDED US OFF TO DEP CTL. I TOLD THIS CTLR SAME THING AND HE SAID HE WAS GOING TO NOTIFY HIS SUPVR TO RELAY OUR RPT. WE HAD FIREWALLED THE ENGS AND AFTER TALKING TO TUL MAINT, DIVERTED TO TUL. SUPPLEMENTAL INFO FROM ACN 333079: THE PROB BEING RPTED HERE IS VERY SIMPLE AND DIRECT -- THE TWR IGNORED OUR EXPERIENCE. THEY ARE SO ACCUSTOMED TO ROUTINE LLWS WARNINGS THAT THEY DO NOT UNDERSTAND THE SEVERITY OF AN ENCOUNTER THAT WOULD COMPEL A CAPT TO SAY, 'STOP ALL DEPS!'
