Large-Scale Dynamics, Anomalous Flows, and Teleconnections
Description
There are still issues in large-scale flow dynamics that have yet to be explored. While the dynamics of large-scale meteorology have been largely described, one outstanding issue is anticipating a change in the hemispheric flow regime. These changes can happen gradually or quite abruptly. Another outstanding issue is predicting the onset or termination of blocking events. Atmospheric blocking typically describes a persistent, midlatitude ridging in the middle and upper troposphere that impedes the regular progression of synoptic-scale cyclones along the storm track. They can also occur episodically and dominate regional flow regimes for an entire season or more. Blocking most recently contributed to the deadly heat wave that occurred over western Russia during the summer of 2010. Large-scale atmospheric dynamics and blocking are also associated with the occurrence of teleconnection patterns. Currently, these are identified through the use of empirically derived indices; however, their dynamics are not well understood.
We are particularly interested in manuscripts that examine the dynamics and predictability of anomalous flows and atmospheric teleconnections, both from a short- and long-range perspective. Also, the examination of stratosphere-troposphere coupling would be a topic of interest. Papers that analyze the causes and the impacts of large-scale events that have led to periods of destructive weather, regardless of season, are also welcomed. Climatological studies that use models to project general circulation features, their future distribution, and their societal impacts would also be of interest to the community. Potential topics include, but are not limited to:
- Dynamics of teleconnections or blocking and predictability
- Large-scale predictability on the seasonal scale
- Climatological studies
- Interannual and interdecadal variability in teleconnections and blocking
- Blocking and climate change
- Stratosphere-troposphere coupling (e.g., sudden stratospheric warming) during blocking
