Stratospheric predictability and sudden stratospheric warming events [PDF]

Journal of Geophysical Research, 2009
A comparative study of the limit of predictability in the stratosphere and troposphere in a coupled general circulation model is carried out using the National Center for Environmental Prediction (NCEP) Climate Forecast System Interactive Ensemble (CFSIE).

Blocking precursors to stratospheric sudden warming events [PDF]

Geophysical Research Letters, 2009
The primary causes for the onset of major, midwinter, stratospheric sudden warming events remain unclear. In this paper, we report that 25 of the 27 events objectively identified in the ERA‐40 dataset for the period 1957–2001 are preceded by blocking patterns in the troposphere. The spatial characteristics of tropospheric blocks prior to sudden warming

Final Sudden Stratospheric Warmings and the memory of the stratosphere

2021
<p>Sudden Stratospheric Warming (SSW) is the most spectacular dynamic event occurring in the middle atmosphere. It can lead to a warming of the winter polar stratosphere by a few tens of K in one to two weeks and a reversal of the stratospheric circulation from wintertime prevailing westerly winds to easterly winds similar to summer ...

A research on the Stratosphereic Sudden Warming

Proceedings of 2011 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference, 2011
In this dissertation, we described the basic measure of detecting atmosphere—the basic component of Radiosonde and it's principle. With the definition of the Stratospheric Sudden Warming (SSW) and the measure of ascertaining the event of the Stratospheric Sudden Warming, my research are mainly focused on finding the case of SSW phenomenon from the ...

Sudden Stratospheric Warmings as Catastrophes

Journal of the Atmospheric Sciences, 1985
The sudden stratospheric warming (SSW) process is qualitatively studied using a conceptual and numerical approach guided by catastrophe theory. A simple example of a catastrophe taken from nonlinear dynamics is given, and results from previous modelling studies of SSW are interpreted in light of catastrophe theory.

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.
