I suspect that, if you read the installation instructions, you will find that properly securing the trampoline is a requirement for a proper installation when wind is expected:

Windy Conditions
It is possible for the trampoline to be blown about by a high wind. If you anticipate high winds, the frame should be
secured to the ground with the use of a JumpSport Trampoline Anchor Kit. If you anticipate severe winds, the
trampoline should be moved to a sheltered location or completely disassembled.
From https://www.skywalkertrampolines.com/manuals/trampoline/SWTC16R_Manual.pdf:
High Wind: The trampoline can be blown around by high winds. If you expect high winds, the trampoline
should be moved to a sheltered location, taken apart, or tied down to the ground with ropes and stakes (NOT
INCLUDED). At least four ropes and four stakes should be used. Make sure to attach the ropes to the top of the
frame: DO NOT simply secure the legs or the bases to the ground, as they can seperate from the frame sockets.
The top of the stakes should be at ground level so they will not create a tripping hazard. In addition, the top of
the stakes should be covered, if necessary, so that users will not be injured by falling on the stakes. The manufactures
warranty does not cover any type of wind or weather damage
