By using an arbitrary initial value for L, u à and T à can be calculated using Eqs.
(2.59) and (2.60), with the w functions obtained through Eqs. (2.61) and (2.62), and
thereafter L is calculated using Eq. (2.50). Using the calculated L value, the procedure is repeated until a value equal or close to the pre-defined L value is obtained.
The final values for u à and T à are lastly calculated using Eqs. (2.59) and (2.60).
According to Eq. (2.40), the sensible heat flux, H, is given by
H ¼ qc p u à T Ã
ð2:65Þ
