| Session Description | Over the last decade there has been an increasing focus on the influences of extratropical atmospheric variability (e.g., NAM/AO, NPO, NAO, SAM/AAO, etc.) and high-latitude thermal forcing (e.g., sea surface temperature modes, snow cover, sea ice, and ocean heat transport, etc.) on the tropical weather and climate systems (e.g., ENSO, ITCZ, IOD, MJO/ISO, tropical cyclones, summer monsoon, etc.). Similarly, the tropical SST variability has also shown a great impact driving the change of Hadley Cell and atmospheric meridional overturning circulation. The associated dynamics and physical processes, such as the ocean-atmosphere interaction, are important for understanding the tropical-extratropical variability and have implications for the interannual to decadal predictability. However, these influences are often poorly understood and represented in current models. Often this is due to a lack of observations of the processes being modelled. Contributions are welcome from, but not limited to, research on observational, theoretical and modeling studies about the influences of extratropical (tropical) forcing on the tropical (extratropical) weather and climate systems on all aspects, including their two-way interactions. |
