you can try simulating wind with PerlinNoise.
I’m writing some example code down, but you really need to play with the numbers, so the wind looks good on your scale:

void FixedUpdate()
{
  Vector3 windDirection = Vector3.left;
  float windMin = 10f;
  float windMax = 30f;
  float windFrequency = 0.1f;
  float currentWindForce = windMin + (windMax-windMin)*Mathf.PerlinNoise(Time.time*windFrequency,0);

  rigidBody.AddForce(currentWindForce * windDirection );
}

Also add some drag on your rigidBody, so the objects don’t increase speed indefinitely
