A physical full-scale experimental set-up was designed and implemented in the wind tunnel to reproduce and capture the trajectories of falling water drops when approaching the collector of catching type precipitation gauges, reproducing rainfall measurements in windy conditions. The experiment allowed to collect, for the first time, a large...

Wind tunnel (WT) experiments were conducted to reproduce the wind-induced deviation of rain drop trajectories when approaching the collector of catching-type gauges. Three typical outer shapes of the instrument body (cylindrical, inverted-conical and "chimney" shapes) were tested using full-scale models. The airflow pattern upstream of and...
