One of the most important stages of the forecasting studies is to obtain the most possible accurate meteorological and snow cover data from the site. In addition to meteorological data which reflects of the general climatological characterization of the region, the data collected from upper zone of the potential avalanche release area is enormously important as well. Therefore, setting up of the automatic avalanche weather station on higher elevations where the potential avalanche hazard exists is an essential stage in terms of avalanche forecast. Advances of sensor and communication technologies delivers getting more quality of data from the field and therefore the installation of the avalanche stations remains up to date. The experiences obtained from an automatic avalanche station installed in the field for research purposes are summarized in this study. The research results offered that initial installations of avalanche stations can be commenced from the ski centers where the avalanche risk and intensive human activities will be experienced most.

The return period of avalanche is one of the variable which are used as input parameters in numerical analysis studies. It is an important parameter because of avalanche itself could be repeated and this situation may affect the analysis results considerably. This parameter can be introduced to the model RAMMS, which is one of the recently updated simulation models, in four different ways. Avalanche return periods is mostly selected by the user in RAMMS. Therefore, the effect of this parameter on the results should be examined. In this context, the results obtained from the analyzes performed at different return periods were evaluated and the effect of the related parameter on the results was investigated herein. The results show that the return periods of avalanche have less effect than release depth and area.
