The Subtropics: Dynamics, variability, predictability and change in Past, Present and Future
Convener: Neil HartECSECS | Co-conveners: Marcia ZilliECSECS, Andries Jan De VriesECSECS, Irina Rudeva
The subtropics present unique regional hydroclimates across the globe, with strong influence from both tropical and mid-latitude processes. These regions have extensive interplay between atmospheric thermodynamics, dynamics, and coupled ocean-atmosphere processes, leading to many subtropical regions emerging as clear hot spots of climate change in past, present, and future climates. However, treatment of the subtropics as simply the margin between low- and mid-latitude dynamics has limited advancement of subtropical research and prediction, resulting in large uncertainties in climate model simulations and undermining regional efforts to manage climate risks. This session is convened to foster the community working on these subtropical climate research gaps. We invite contributions focused on weather and climate processes in observations and their simulation in either or both hemispheres, including:

• weather and climate extremes in the subtropics;
• tropical-extratropical interactions;
• subtropical jet fluctuations;
• interplays between monsoons and mid-latitude transient eddies;
• diagonal convergence zones;
• analyses of climate simulations looking into past, present and future change in the subtropics;
• development of climate services based on advances in subtropical theory and prediction.
