| Abstract: | Standard deviations for vertical velocity and scalar quantities, such as temperature, T, and specific humidity, q, were analyzed on the basis of Monin-Obukhov (M-O) similarity theory in the atmospheric surface layer. The correlation coefficient between scalar quantities T and q,  RTq, was derived from the similarity functions and can be expressed as the ratio of BT/Bq (BT≤ Bq), where parameter B is the value of the normalized standard deviation of any scalar quantity at neutral conditions. |
