Hydroclimatic Extremes and Impacts in Regional Climate Modeling: Observations, Mechanisms, and Projections

Dear Colleagues,

With the ongoing global warming, the spatial-temporal characteristics of extreme hydrometeorological events such as flood, drought, and extreme heavy precipitation have changed at global and regional scales. These disruptive changes have caused significant impacts on economy, energy, ecology and human life and attracted extensive attention from many scholars worldwide. The in-depth understanding and accurate prediction of these events are critical to management's emergency response and the mitigation of negative impacts. However, regional geographical and climatic differences and the impact of human activities make it difficult to understand the complex mechanisms causing hydroclimatic extremes, which is further exacerbated by the interdependence and potentially destructive effects of risk factors. High-resolution regional climate models can capture the subtle variations of extreme precipitation from sub-hourly to seasonal scales through better representing convection and orographic forcing, effectively improving the accuracy of precipitation process simulation. Therefore, regional climate models play a key role in studying the complex impacts of climate change and human activities on extreme hydrometeorological events, and have been widely used in related studies. To this end, this Special Issue aims to gather the most important contributions to theoretical developments and scientific advances related to hydroclimatic extremes and impacts in regional climate modeling. Major topics of interest include, but are not limited to:

1. Historical, current and future hydroclimate detection and attribution studies based on regional climate models and observations.
2. Coupling modeling, assessment, improvement, and uncertainty analysis of regional climate models and hydrological models.
3. Regional climate model applications in hydroclimatology, including the assessment and prediction of the impact of climate change on extreme hydroclimatic events such as floods, droughts, and heavy precipitation.
4. Studies of the impact of human activities such as agricultural irrigation, soil and water conservation, water transfer projects, and afforestation on regional-scale extreme hydroclimate events.
5. Measures and suggestions for mitigating or responding to extreme hydroclimatic events under climate change.
