Although the issue of climate change is often dealt with in global perspective, the impact of climate change must be assessed at regional scales. While global climate models can provide projections of the average state of large-scale circulation of future climate, the downscaling of such projections to regional scale with improved spatial and temporal resolution for both the forcing fields and the climatic responses is the starting point for assessing the impact of climate change. Therefore, it is important to not only study climate change at global scale, but also study the regional manifestations of the climate system at spatial scales ranging from hundreds to thousands of kilometers with time scales of months to years to decades.

In this special issue, we call for papers dealing with recent advances in in situ and remote observing systems, analysis, statistical and dynamic downscaling and prediction, and impact assessments pertaining to regional climate systems. Potential topics include, but are not limited to:

• Observational methods and analysis of climate systems at regional scales
• Regional climate modeling and downscaling
• Regional climate prediction
• Assessment of regional impacts of climate change
• Extremes of regional climate variability
• Forcing in regional climate systems
