The High Mountain Asia (HMA) is hosting the largest ice stock after the polar regions. This resource provides a freshwater supply to nearly 1.4 billion people, making it a particularly vulnerable region to climate change. HMA includes the highest …
Mickaël Lalande est doctorant en géosciences à l'Université Grenoble Alpes.
Il travaille sur la modélisation climatique. Cela ne vous dit rien ? Il s'agit de diviser la planète en cubes et de calculer les variables climatiques pour faire des projections, facile !
Snow cover strongly modulates the energy fluxes between the atmosphere and the Earth’s surface. Indeed, snow has generally a much higher albedo compared to other surfaces and therefore reduces the amount of solar radiation absorbed by the surface. …
With an average elevation of 4000 m, High Mountain Asia (HMA) and the Tibetan Plateau (TP) are hosting the third largest reservoir of glaciers and snow after the two polar ice caps, and trigger strong rates of orographic precipitation. Climate …

Climate change over High Mountain Asia is investigated with CMIP6 climate models. A general cold bias is found in this area, often related to a snow cover overestimation in the models. Ensemble experiments generally encompass the past observed trends, suggesting that even biased models can reproduce the trends. Depending on the future scenario, a warming from 1.9 to 6.5 °C, associated with a snow cover decrease and precipitation increase, is expected at the end of the 21st century.
