 WINDS FOR FRICTIONLESS MOTION IN H/CHS AND LOWS. 



Metric Measures. 



Re = radius of critical curvature in kilometers. Ve High = maximum speed in meters per 

 second on isobar of critical curvature. Vs = speed along straight line isobars = 0.5 Vc. V Low = 

 speed in Low along isobar of curvature Re- V Low = 0.4142 Vc. 



The remarks in heading of Table 40 relative to the density of the air apply equally to Table 41.
