The coastal zones are unique and dynamic natural environments where a range of interactions between atmospheric, oceanic, and land processes lead to sharp gradients in environmental conditions. Understanding these interactions is vital for accurate weather and climate predictions, requiring monitoring and modeling at sufficiently high spatial and temporal scales. We invite submissions based on observations (field-based, gridded, reanalyses) and models (NWP and climate/earth system) that examine coastal processes and interactions on weather and climate timescales and discuss how the coastal regions across the globe are impacted by changing climate conditions. Submissions could include studies focusing on meteorological phenomenon such as sea breeze, fronts, lake-effect snow, and coastal storms, and on processes acting on climate timescales including the effects of boundary currents, ocean circulation changes, and sea level rise on coastal environments. We also invite submissions that use a variety of modeling approaches such as regional and global high-resolution climate modeling as well as statistical downscaling techniques to improve our understanding of coastal climate dynamics, and studies that focus on marine heat waves and compound extreme events over land in coastal regions.
