Atmospheric teleconnections link and influence weather and climate across geographically distant regions and can have far-reaching societal impacts. Understanding how specific teleconnections can modulate regional extremes and affect societal outcomes (for example water scarcity, agricultural impacts, disease spread or increased morbidity and mortality) is critical for anticipating their consequences.

This session invites a broad range of contributions investigating atmospheric teleconnections, their influence on regional climate variability and extremes, and their societal impacts. We welcome submissions focusing on different types of atmospheric teleconnections, their influence on regional extremes and those describing their sectorial impacts including agriculture, disease propagation, human health, water and food security and socio-economic impacts. Contributions may address subseasonal, seasonal, interannual or decadal timescales and focus on past climates, historical periods or future projections.

We particularly encourage studies that connect atmospheric teleconnection changes to real-world outcomes, using a broad range of tools, from observations, reanalyses, regional and Earth System models. These may include the links with climate-sensitive diseases (dengue, chikungunya, Zika, malaria etc.) or the assessment of crop yields and other agricultural or economic impacts Finally, as teleconnections underpin much of the skill of subseasonal-to-decadal forecasts, we also welcome contributions on how this knowledge is used in prediction, early warning systems and climate services.
