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 25 kt at "ridgetop" level of 700 mb (approx. 10,500 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 18 kt at "ridgetop" level of 700 mb (approx. 10,500 ft)
These criteria based on the those empirically developed
for the Sierra wave by Doug Armstrong of the Reno NWS

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.
