Résumé:
This study aims to compare means and daily values of precipitable water calculated in empirical form
to cities of South America, and dividing it by regions, with calculated values of precipitable water in
aerologic method, from values to weather variables obtained from radiossondagens. Were used 15
days of data radiossondagens during the month of June 2008. For empirical analysis we used three
methods to calculate the precipitable water, these are the method of Allen, the method Won and the
method of Hann. The values obtained by three methods were compared with the aerological method
of Harrison, which is considered more accurate than the empirical methods. In general, for values
calculated empirically which showed better correlation with the method of Harrison was the method of
Hann, while for the daily values, the empirical method that showed the best correlation was the
method of Allen.
