Some lighter tripods have a hook on the bottom of the centre column where you can hang a camera bag, your shopping or a sack of rocks. This moves the centre of mass of the tripod/camera lower, so it's more likely to be inside the triangular footprint of the tripod, even when wind pushes things to one side (so it's a centre of forces rather than of mass). It's worth making sure the tripod is capable of supporting the additional weight.

A heavier camera on its own is unlikely to help much, as the centre of mass will still be high giving a greater chance of tipping once the wind catches it (unless the tripod provides for "reversed" mounting of the camera on the bottom of the column). And, if the heavier camera is also larger, that will give more area for the wind to catch.

Something even heavier on the ground and a bungee cord to the hook might also be worth trying - possibly also a camping-style screw-in ground anchor (no good on loose sand or concrete, though).

The trick is to keep the centre of the forces - including weight and the lateral force from the wind - inside the triangular footprint of the tripod.
