DOI: 10.1002/qj.3858
Abstract: Two recent occurrences in February 2018 and January 2019 of a dynamic split in the Northern Hemisphere stratospheric polar vortex are compared in terms of their evolution and predictability. The 2018 split vortex was associated… read more here.

DOI: 10.1175/bams-d-16-0259.1
Abstract: AbstractThe extratropical stratosphere in boreal winter is characterized by a strong circumpolar westerly jet, confining the coldest temperatures at high latitudes. The jet, referred to as the stratospheric polar vortex, is predominantly zonal and centered… read more here.

DOI: 10.1175/jcli-d-17-0097.1
Abstract: AbstractStatistical models of climate generally regard climate variability as anomalies about a climatological seasonal cycle, which are treated as a stationary stochastic process plus a long-term seasonally dependent trend. However, the climate system has deterministic… read more here.

DOI: 10.3390/atmos14050870
Abstract: The year-to-year varying annual evolutions of the stratospheric polar vortex (SPV) have an important downward impact on the weather and climate from winter to summer and thus potential implications for seasonal forecasts. This study constructs… read more here.
