Meðalrakastig á hverjum athugunartíma er reiknað með þvi að taka hlutfallið milli meðalraka-
þrýstings og mettunarþrýstings við meðalhitastig athugunartímans. Rakastig mánaðarins er á sama
hátt miðað við hlutfall milli meðalrakaþrýstings í mánuðinum og mettunarþrýstings við meðalhita
mánaðarlns. Ársmeðaltöl eru bein meðaltöl af rakastigum mánaðanna.
Relative humidity at fixed hours and mean monthly values are computed according to the for-
mula V — e/em ■ 100 where e and em stand for mean vapour pressure and saturation vapour pres-
sure at the respective mean temperature. The yearly mean is aritlimetic mean of the monthly values
for relative liumidity.
