The criterion "mt. wave" windspeeds used for this site are:
To have a mt. wave somewhere (indicated by "+" marks)
  (1) windspeed of 65 kt at 300 mb (approx. 31,000 ft)
  (2) windspeed of 20 kt at "ridgetop" level of 850 mb (approx. 5,000 ft)
To have a mt. wave at designated ridge (indicated by "*" marks)
  (1) perpendicular wind of 46 kt at 300 mb (approx. 31,000 ft)
  (2) perpendicular wind of 14 kt at "ridgetop" level of 850 mb (approx. 5,000 ft)
These criteria based upon those of Doug Armstrong and Peter Kelly

Please recognize that the utilized mt. wave criterion is simplistic
while mt. wave behavior can be complex, so the simple yes/no program
predictions cannot be expected to cover all mt. wave occurrences.
