Abstract: <p>During the Last Glacial Maximum (LGM), a very cold and dry period around 26.5&#8211;19&#8201;kyr&#8201;BP, permafrost was widespread across Europe. In this work, we explore the possible benefit of using regional climate model data to improve the permafrost representation in France, decipher how the atmospheric circulation affects the permafrost boundaries in the models, and test the role of ground thermal contraction cracking in wedge development during the LGM. With these aims, criteria for possible the...
