Session Description
Snow Level is closely tied to Precipitation Intensity, and both factors change dramatically
with individual weather systems and climate change. Modeling of the melting snow
transition layer, through which precipitation melts from snow into rain is critical for
accurate snow level forecasting. Also, the heavier the precipitation rate, the greater the
cooling required in the atmosphere to melt the snow, and the lower the snow level. A
series of interrelated processes occur in the melting snow transition layer that can be
observed with a variety of instruments, and can be tracked with time. The intensity of
precipitation is expected to increase with global warming, and there already is some
suggestion that convective precipitation is increasing on earth. In recent years we have
been experiencing repeated record breaking precipitation events, and impactful snow
level changes. How more frequent will extreme events now occur? The impacts caused
by more intense precipitation with or without rapidly varying snow levels, can be
extreme. The current trends are for the snow level to rise, however with more intense
precipitation it is possible deep snow will still accumulate at the highest elevations. All
papers related to snow level and precipitation, from observations to modeling, past
present and future are invited. Studies that provide new insight into remote sensing of
melting snow layer properties and the physics controlling precipitation and snow level
variations are invited. Innovative new methods are welcome, including isotopic
applications. Studies that focus on precipitation intensity and detection of shifts and
extremes are also welcome. Investigations on the impacts of past snow level and
precipitation intensity changes are needed, to improve our understanding of current trends
and extremes, so we can accurately warn and effectively prepare for change. In addition,
related regional impact studies such as flooding, avalanche and water supply changes are
welcome.
