LCL | R Documentation |
Find the pressure and temperature at the lifted condensation level
LCL(p, t, r)
p |
The pressure [hPa] of the air parcel |
t |
The temperature [degC] of the air parcel |
r |
The water vapor mixing ratio of the air parcel [dimensionless, NOT g/kg] |
Solves iteratively for the pressure at which, for the given potential temperature and mixing ratio, the equilibrium vapor pressure at that pressure level would match that required to give the specified mixing ratio. Note for comparison the Bolton formula: (2840 / 3.5*log(T+273.15)-log(e)-4.805)+55
