报告题目：美国西部的水文变化（Hydrological Changes in the Western United States）
报 告 人：美国工程院院士，美国加州大学洛杉矶分校（UCLA）杰出教授，美国地球物理联合会（AGU）、美国气象学会（AMS）、美国科学促进会（AAAS）会士，Dennis Patrick Lettenmaier （丹尼斯·莱滕迈尔）教授
报告摘要：
本讲座系统阐述了全球变暖对美国西部水循环的影响模式与机制。过去75年间，变暖导致美国西部冬季雨雪比增加、积雪量减少、冰川萎缩；同时显著提前了春季融雪径流的起始时间与峰值出现时间，也降低了雨雪洪水的频率与强度。讲座还深入探讨了关键科学问题，包括暖季与寒季变暖对水文效应的差异、夏季径流变化及其可预测性，以及年径流变化模拟与预测的主要控制因素。
This lecture systematically introduces the patterns and mechanisms of the impact of global warming on the water cycle in the Western United States. Over the past 75 years, warming has increased the ratio of rain to snow in winter in the Western United States, reduced snow accumulation, and caused glacial shrinkage; it has also led to a significant advance in the start time and peak occurrence time of spring snowmelt runoff, as well as a decrease in the frequency and intensity of rain and snow floods. This lecture also elaborated on key scientific issues such as the differences in hydrological effects between warming in warm seasons and cold seasons, changes in summer runoff and its predictability, and the main controlling factors for the simulation and prediction of annual runoff changes.

报告摘要：
采用格点化的气象观测数据CN05.1驱动VIC（Variable Infiltration Capacity）陆面水文模式，并利用中国高精度土壤及植被参数数据集，模拟构建了一套中国1961~2022年逐日0.25°×0.25°地表水文数据集（VIC-CN05.1），包含了总径流深、蒸散发、土壤湿度、雪水当量和陆地水储量等地表水文变量。与多源观测数据比较表明，该数据重建了中国区域过去60年以来中国区域陆面水文过程的时空变化特征。进一步，利用CaMa-Flood水动力模型对多源径流在主要河流进行汇流后，与水文站点实测河道流量对比发现，VIC-CN05.1径流量优于当前主要的再分析产品。最后，以VIC-CaMa-Flood 搭建了区域洪水预警系统，对多起洪水事件开展了回报及预报试验。
A grid based meteorological observation data CN05.1 was used to drive the VIC (Variable Infiltration Capacity) land surface hydrological model, and a high-precision soil and vegetation parameter dataset from China was used to simulate and construct a daily 0.25 °× 0.25 ° surface hydrological dataset (VIC-CN05.1) for China from 1961 to 2022, which includes surface hydrological variables such as total runoff depth, evapotranspiration, soil moisture, snow water equivalent, and land water storage. Compared with multi-source observation data, this data reconstructed the spatiotemporal variation characteristics of land surface hydrological processes in China over the past 60 years. Furthermore, using the CaMa Flood hydrodynamic model to converge multi-source runoff in major rivers, it was found that the VIC-CN05.1 runoff was superior to the current main reanalysis products when compared with the measured river flow at hydrological stations. Finally, a regional flood warning system was established using VIC Ca Ma Flood to conduct reporting and forecasting experiments on multiple flood events.
