Formulas and expressions to Calculate "standard" variables

Contents

Temperature (°K)

  • Reference: [1]
 Temp = (T+300)((PB+P)/100000)^{2/7} 
 Temp and T, are in °K
 PB and P, are in pa

Pressure (mB)

  Pres = P + PB 

Relative Humidity (fraction)

  H = \frac{q2}{(pq0 / psfc) e^{a2 \frac{t2 - a3}{t2 - a4}}}
where:
   let pq0 = 379.90516
   let a2  =  17.2693882
   let a3  = 273.16
   let a4  =  35.86
