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  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.

as a key mechanism of Indian Ocean climate variability," Deep-Sea Research I, vol.
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., ) are often associated with a large scale stationary Rossby wave
pattern Fischer (see  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
 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.
 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).
