Abstract :
The work reported in This work further extends work presented in a companion paper and uses ground based meteorological observations to predict the long-term annual average value of the k-factor. These results are compared with those obtained from the radiosonde data used in the companion paper. The results are in broad agreement with those obtained from radiosonde observations. However, it is found that there are discrepancies in the comparison for Alexander Bay data. This may be due to the influence of the cold Benguela current.
