Rossby waves (RW) propagation due to a local forcing is one of the mechanisms responsible for wave trains configurations known as teleconnections. The term teleconnection refers to anomalies patterns that are c
The results reveal that all three EU patterns are characterised by a clear quasi-barotropic wave-train structure, but each has a distinct source and centre of action. Accordingly, their impacts on the precipitation and surface air temperature also differ from one other. Further evidence suggests ...
a–eGlobal SST and (k–o) equatorial Pacific subsurface ocean temperature patterns associated with TPDV in (a,f,k) observations (SST in ERSSTv5 and ocean temperature in EN4), (b,g,l) the forced ocean-sea ice simulation (FOSI), and theensemble-meansof (c,h,m) CESM1 DPLE, (d,i,...
Here we show that such challenges can be attributed to anomalous atmospheric pressure patterns in the Western North Pacific (WNP) region. The anticyclonic circulation anomaly over WNP region causes the easterly wind toward the Indian subcontinent, leading to positive precipitation anomalies with stronger...
This is likely due to two factors: (i) the movement of wave crests and troughs continuously alters the stratification of the upper ocean, generating a positive baroclinic instability and prompting conversions of EKE from mean flow in the source regions, and (ii) wave-current interactions induce...
The teleconnection patterns in the RPCA approach are identified based on the entire flow field over the Northern Hemisphere, and not just from height anomalies at select locations, so it can get better continuity of the time series and robust patterns. VPD is calculated from maximum temperature ...
an enhanced spring and summer soil moisture as well as some significant patterns on the downstream side of the continent, as the deepening of the Aleutian low in the North Pacific Ocean, enhanced east Asian westerly winds, negative 500 hPa height anomalies or the strengthening of the North Paci...
Rossby waves associated with vortex variability reproduce aNAO-like dipole over theAtlantic Ocean but no dipole is formed over the Pacific Ocean.Moreover, results suggest that the nonlinear wave response to topographic forcingmay explain the spatial changes of the NAO correlation patterns that have be...
The boreal summer and boreal winter patterns are accurately represented by a bimodal index (Kikuchi and Wang, 2010; Kikuchi et al., 2012), which consists of the MJO and the boreal summer intraseasonal oscillation (BSISO, or MISO; May–October). Several indexes are developed to track the ...
