As I'm only used to c-script this may be false, but I would move the PANEL* pDisplay out of the function and instead just set the flag of that panel to visible inside the function:
Code:

---

PANEL* pDisplay =
{
  digits (35, 10, "Global Wind Speed: = %0.f", "Arial#16b", 1, vGlobal_Wind_Speed);
  digits (35, 30, "Local Wind 1: = %0.f", "Arial#16b", 1, vLocal_Wind_1);
  digits (35, 70, "Object 1: = %s", "Arial#16b", 1, sMessage);
}

function display_results()
{
  set(pDisplay,VISIBLE);
}
