Disse Værdier for Trykket ere afsatte i Kartet PI.
XLIV, og efter dem er der trukket Linier for ligestort
Tryk — Isobarer— for hver Hundrededels Atmosfære. Da
Trykforskjellerne i 300 Favnes Niveauflade ere de samme
som Vindfladens, løbe disse Isobarer ganske som Vindfladens
Ligehøjdelinier.
Førend vi studere den af Trykfordelingen foraarsagede
Bevægelse i denne Niveauflade, skulle vi beregne Trykkenes
Fordeling i Niveaufladerne II— 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 ofl’ on the map
PI. 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 H= 1500 fms.;
p is computed according to the formulæ p. 155; S denotes
the ordinates of the current-surface, divided by 10.
