The research found that the same large-scale meteorological event - an abnormal
Rossby wave - sparked extreme heat and persistent wildfires in Russia as well as unusual downstream wind patterns that shifted rainfall in the Indian monsoon region and fuelled heavy flooding in Pakistan.
In the theory of the vertical propagation of planetary waves, Charney and Drazin [33] pointed out that a
Rossby wave can only propagate in westerlies.
The prominent Okhotsk high in August 2017 formed in association with the propagation of a stationary
Rossby wave in the middle-upper troposphere from Europe through East Siberia (Fig.

Rossby wave as a key mechanism of Indian Ocean climate variability," Deep-Sea Research I, vol.
Rossby wave breaking leads to PV filamentation, forming smaller-scale PV anomalies such as PV streamers and cutoff vortices.
Furthermore, circulation anomalies as blocking storm tracks and frontal systems (e.g., [21]) are often associated with a large scale stationary
Rossby wave pattern Fischer (see [14] and references therein).
2010), tend to upwell the local thermocline and drive westward-propagating cold
Rossby waves. During December 2016-February 2017, cold upper-300-m mean temperature anomalies occurred along 10[degrees]S and in the western IO, reminiscent of the
Rossby wave activities (Fig.
[52] suggested that a
Rossby wave train propagates from northeast of India to Canada in response to SST changes linked to the IOD.
The atmospheric ENSO teleconnection in November and December is reminiscent of the east Atlantic pattern and distinct from the well-known arching extratropical
Rossby wave train found from January to March.
[31] found that anomalous convection from El Nino instigates a
Rossby wave train in austral winter from the central equatorial Pacific poleward, which is known as the Pacific South American (PSA) pattern [32, 33].
The vortex
Rossby wave (VRW) has been proposed to explain the formation of typhoon rainbands (Montgomery and Kallenbach 1997).
