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

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

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



The remarks in heading of Table 42 relative to the density of the air apply equally to Table 43.
