According to DJI, the Air 2 takeoff weight is 570g (1.25lbs), with wind resistance of 18-24mph. The Air 3S takeoff weight is 720g (1.6lbs), with wind resistance of 27mph.
Even though the weight difference isn't much, I'd think the Air 3S would do way better in windy conditions than the Air 2. I've only had my 3S since March, and haven't had a chance to take it out on a windy day yet.
The only thing that matters when dealing with wind is how fast can the drone fly in still air.
The faster the drone can push through the air, the better it can deal with wind. Air 2 Max speed = 19 metres/sec
Air 3S Max speed = 21 metres/sec.
