| Session Description | Mesoscale processes (2-2000km) are weather phenomena smaller than synoptic scale but larger than microscale and storm-scale cumulus, including Meso-alpha systems (fronts, squall lines, MCS, tropical cyclones), Meso-beta systems (land sea breezes, low-level jet) and Meso-gamma systems (thunderstorm convection, terrain flows, tornadoes). Recently, an increasing number of high-impact weather events related to hazard, like local heavy rainfall, landslides, flash flooding and high wind, are found to be associated with mesoscale systems. So, improving our understanding of mesoscale weather systems is the first step to prevent huge economic and human losses from these disasters. This session invites and welcomes contributions from all aspects of mesoscale processes, which include but are not limited to observational, theoretical, modeling, and climate and weather-related studies of (1) extratropical and tropical cyclones; (2) Mei-yu (Baiu and Changma) front; (3) mesoscale convection; (4) diurnal cycle of precipitation; (5) mesoscale predictability; (6) orographic flows and rainfall; (7) severe weather and its variation under climate change. This session will provide a platform to assess our progress and limitation of understanding of mesoscale processes and help us make a breakthrough in this field. |
