スコープ The moist atmosphere spontaneously generates a variety of interacting phenomena that span a wide range of spatial and temporal scales. Water vapor, clouds, and precipitation play essential roles in regulating the global circulation through radiative, microphysical, and dynamical processes. The large-scale overturning circulation, for instance, is maintained by the longwave radiative cooling of water vapor and the compensating latent heating associated with cloud systems. Within this circulation, diverse phenomena emerge from turbulent motions in clouds and shallow cumulus convection to mesoscale systems such as squall lines and tropical cyclones, and further to planetary-scale variability such as the Madden–Julian Oscillation (MJO). This hierarchical structure, while prominent in the tropics, also exerts profound influences on, and is in turn modulated by, the extratropics.
Moisture tends to accumulate and be transported on larger spatial scales but is rapidly consumed on smaller scales, leading to scale gaps between energy and moisture sources and sinks. Understanding how these moist processes interact across scales to organize the circulation, not limited to individual convection, remains one of the central challenges in atmospheric science.
This session aims to explore recent advances in understanding the broad spectrum of moist atmospheric phenomena and their interconnections, bridging multiple scales and processes. We welcome studies that approach this topic from modeling, observational, and theoretical perspectives, including innovative AI/ML or mathematical physics approaches. Example themes include the dynamics of the MJO and tropical cyclones, analyses of organized convection and extreme weather systems, cloud statistics from satellite observations, radiative–convective equilibrium studies, tropical-extratropical coupling such as atmospheric rivers, and high-resolution simulations using global storm-resolving models.
