This week we host Jane Baldwin, PhD candidate in Princeton’s Atmospheric and Oceanic Science Dept., who studies the reasons that deserts exist in Asia. Jane first wondered about the changing climate of the steppes of Inner Mongolia, where famous grasslands have slowly morphed to low, dry shrubs. Surprisingly, she found a more fundamental question that needed study first: why do Asian deserts, like the Taklamakan and Gobi, exist in general? Global climate simulations give researchers a crucial tool to study WHY the climate works as it does, so Jane tested various hypotheses about the Taklamakan: does it still exist if you run a simulation without Tibet? Without Europe taking moisture from Asia’s westerly winds? Without the Tian Shan mountains, which lie between the Taklamakan and the Gobi? Tune in for surprising results that hint how important well-placed mountains can be for the climate.
