Dynamics of the Asian Summer Monsoon Anticyclone: insights from potential vorticity tendency diagnostics

The Asian Summer Monsoon Anticyclone (ASMA), the dominant circulation in the upper troposphere and lower stratosphere (UTLS) during the boreal summer, undergoes pronounced spatio-temporal variability. While the climatological mean state of the ASMA is well documented, the mechani...

Forecast-based attribution of the role of stratospheric variability in weather extremes

Abstract. Variability of the stratospheric polar vortex, particularly its dramatic breakdown during sudden stratospheric warming (SSW) events, has been linked to a number of surface weather extremes. However, attributing the role of stratospheric variability in a specific observe...
