In that kind of weather, some margin about normal Vref should be applied, isn't it?
Not so in all 737 models 200 to 900, 757, 767 and 777 according to Boeing SOP's when the A/T is engaged. The A320/319 (and other buses I believe) use a feature called 'ground speed mini' which could be quite startling in very strong winds!
