KARRONTE is motivated by the controversial Karakoram Anomaly in High-Mountain Asia, which denotes the relative mass balance stability of glaciers in the Karakoram region under global warming, compared to the massive ice loss observed in other high-mountain glaciers. Recently, some possible explanations have been proposed in the literature, but all of them are based on coarse-resolution data sets, due to the scarcity of weather station data. The need for a new regional climate simulation for the Karakoram using convection-permitting scales is clear. These scales will allow the climate model to resolve convection directly in a physically consistent way, without the need for a cumulus parameterization scheme.
Thus, the main objectives of KARRONTE are the following: (1) To create a novel regional climate simulation for the Karakoram, covering the last 15 years and adopting a spatial resolution of 3 km in the Weather Research and Forecasting (WRF) model. (2) To evaluate the temporal and spatial variability of precipitation and extreme events. (3) To investigate the relationship between recent trends of precipitation, local atmospheric dynamics and teleconnection patterns worldwide. These objectives will allow us to understand the drivers of extreme precipitation and the atmospheric dynamics in the Karakoram region, and to disentangle complex, local atmospheric effects related to the Karakoram Anomaly that could have been missed in previous analyses.
KARRONTE will contribute to the evaluation of extreme event impacts and climate adaptation strategies. Its outcomes will also provide tools and fundamental knowledge to understand the effects of climate change on other high-mountain environments, such as those in Europe and other continents. Regarding my research career, KARRONTE will foster my independence and my ability to attract funding, and it will enable me to develop the competencies and skills valuable to become a young research group leader in the near future.ver más
