Simulated sudden stratospheric warming; synoptic evolution

Quarterly Journal of the Royal Meteorological Society, 1987
AbstractAn analysis is presented of a sudden stratospheric warming event which occurred spontaneously during a general circulation model simulation of the global atmospheric circulation. Two separate warming pulses exhibit the same dynamical evolution with a ‘cycle’ of about two weeks.

Reduced stratospheric variability following sudden stratospheric warming events

2023
Sudden stratospheric warming (SSW) events can form a window of forecast opportunity for polar vortex predictions on subseasonal-to-seasonal time scales. Analysing numerical ensemble simulations, we show that negative wind anomalies in the polar stratosphere following SSWs lead to a reduction in upward planetary wave propagation and hence a reduction in

Stratosphere-mesosphere coupling during stratospheric sudden warming events

Advances in Space Research, 2014
Abstract In this review article we summarize recent results in the coupling of the stratosphere–mesosphere during stratospheric sudden warming (SSW) events. We focus on the role of planetary and gravity waves in driving the middle atmosphere circulation and illustrate the stratosphere–mesosphere coupling during undisturbed wintertime circulation ...

Polar stratosphere dynamics during early sudden stratospheric warmings

Optika atmosfery i okeana
Внезапные стратосферные потепления (ВСП) значительно влияют на погоду в тропосфере и на динамику верхних слоев атмосферы. Определение ВСП и их классификация сформулированы достаточно давно, однако о ранних (в ноябре – первой половине декабря) ВСП подробная информация отсутствует. В работе исследовано влияние ранних ВСП на стратосферный полярный вихрь с
