Mountain Weather and Climate in a Warmer World

Session ID#: 79388

Session Description:
Increasing evidence shows that mountains worldwide are experiencing particularly rapid environmental change. Warming rates are often elevation-dependent, and sometimes faster at higher elevations. However, mountain climate is also extremely spatially heterogeneous: steep slopes and differential aspects create rapid local-scale gradients in climate parameters. The wide range of ecological zones can include the presence of snow and ice.

 

This session seeks to better understand weather/climate processes and patterns of climate change in mountains, as well as their implications for high-elevations and regions downstream. The Mountain Research Initiative invites submissions which use in situ observations and/or remote sensing and/or modelling approaches. We particularly encourage contributions that merge various data sources and/or cross disciplinary borders (atmospheric, hydrological, cryospheric, and ecological sciences), and meta-studies comparing mountain regions or taking a global perspective. A synthesis contribution based on the session is planned as input for the IPCC AR6 and its Cross Chapter on Mountains.

1621 Cryospheric change [GLOBAL CHANGE]
1630 Impacts of global change [GLOBAL CHANGE]
