Tn three of these cases the direction of the wind as reported 
Was outward from the center of the low area, and for the first 
when 7=0. For the first three lines the computed gradients 
(multiplied by 1°32) agree well with the observed gradients ; 
but for the fourth line the computed gradients are too great, 
and for the fifth line they are too small. The wind velocities 
reported by the vessels 12-18 are greater than are usually
