説明
<jats:title>Abstarct</jats:title><jats:p>Meteorological data from mountainous areas of Japan have been collected by the National Research Institute for Earth Science and Disaster Prevention (NIED) for almost 20 years. The collected long-period data indicate that neither a notable increase in mean winter temperature nor a reduction in snow depth has occurred in these areas. The maximum snow depth, SD<jats:sub>max</jats:sub>, and maximum snow water equivalent, SWE<jats:sub>max</jats:sub>, show similar fluctuation trends, although with large year-to-year variations in value and a larger fluctuation range for SWE<jats:sub>max</jats:sub> than for SD<jats:sub>max</jats:sub>. This result suggests that monitoring of only SD<jats:sub>max</jats:sub> in mountainous areas is not sufficient for understanding the quantitative fluctuation of water resources originating from snow. The SD<jats:sub>max</jats:sub> fluctuation trends in mountainous areas sometimes differ from those in flatland areas because mountain SD<jats:sub>max</jats:sub> depends more on winter precipitation than on mean winter air temperature, whereas the opposite is true for flatlands. In addition, the dependence ratio of SD<jats:sub>max</jats:sub> on fluctuations in winter precipitation changes with altitude because the distributions of precipitation with air temperature change with altitude.</jats:p>
