Disse Verdier for Trykket ere afsatte i Kartet PI. 
XLIV, og efter dem er der trukket Linier for ligestort 
Tryk — Isobarer — for hver Hnndrededels Atmosfære. Da 
Trykforskjellerne i 300 Favnes Niveauflade ere de samme 
som Vindfladens, lobe disse Isobarer ganske som Vindfladens 
Ligehøjdelinier. 
Førend vi studere den af Trykfordelingen foraarsagede 
Bevægelse i denne Niveautlade, skulle vi beregne Trykkenes 
Fordeling 1 Niveaufladerne H= 500 Fv., H= 1000 Fv. og 
H= 1500 Fv. p beregnes efter Formlerne Side 155. $S er 
Strømfladens Ordinater, dividerede med 10.

These values for the pressure are set off on the map 
Pl. XLIV; and in accordance with them lines of equal 
pressure — isobars — have been drawn for every 0.01 of 
an atmosphere. The difference in pressure at a surface of 
level 300 fathoms deep being the same as at the wind- 
surface, these isobars run precisely as do the lines of equal 
height of the wind-surface. 
Before passing on to study the motion caused by the 
distribution of pressure over this surface of level, we will 
first compute the distribution of the pressure over the surfaces 
of level H= 500 fms., H= 1000 fms., and = 1500 fms.; 
p is computed according to the formule p. 155; S denotes 
the ordinates of the current-surface, divided by 10.
