It is very important for disaster prevention and flood control to predict sever rainfall in mountain regions.The accuracy of rainfall prediction, however, is not enough because of the complexity of meteorologicalcharacteristics caused by the steep mountains and valleys.
To investigate meteorological quantities, experimental observations have been performed 1998-1999 inand around Kurobe-Valley. In this paper, three types of observations 1) Doppler radar to measure rainfallecho around Kurobe-Valley 2) Mini-radar to measure rainfall echo in Kurobe-Valley 3) GPS sonde tomeasure profiles of meteorological quantities (temperature, specific humidity and winds) are presented.It is found that some local phenomena are occurred in steep mountain regions at time of heavy rainfall andnew ideas and instruments using in this experiments are effective to observe that phenomena.
