Research progress on simulation of high-altitude glaciers and permafrost on the qinghai-tibet plateau based on hydrological models

Abstract

The Qinghai-Tibet Plateau's uniqueness: The Qinghai-Tibet Plateau is located in a high-altitude region, with a much higher average elevation than the surrounding areas at the same latitude. It is home to the majority of the world's glaciers and permafrost in the middle and lower latitudes. Glaciers are extremely sensitive to climate change, and the unique glaciers and permafrost on the Qinghai-Tibet Plateau are especially vulnerable. The predecessors simulated and predicted glaciers using the distributed hydrological model and the glacier system model, and frozen soil using the accumulated temperature statistical model and the freezing number model. Simultaneously, these models have gone through a development process from low-end to high-end, which improves the accuracy and fit of the Qinghai-Tibet Plateau study. This paper will compare the advantages and disadvantages of these distributed hydrological models and glacier system models using a literature review method. We discovered that the glacier model's distributed hydrological model can simulate and analyze glacier runoff, and the Glacer's system model can better classify the glacier. The freezing mumer model has made significant contributions to the dynamic change simulation of frozen soil and the estimation of its maximum thawing depth.
