Possible Mechanism for the Record‐Breaking Cold Event Over Northeastern China in December 2023: Role of Extreme Negative North Atlantic Oscillation

open access: yesAtmospheric Science Letters, Volume 27, Issue 6, June 2026.
In early winter of 2023, an extreme negative North Atlantic Oscillation (NAO) event occurs. Subsequently, the NAO‐related Barents–Kara Seas high drives cold air southward into Siberia, enhancing the Siberian High. Upper‐level convergence and subsidence further contribute to its intensification, leading to the development of the historically strongest ...

Climate networks suggest Rossby-waves–related CO

open access: yes, 2020
The role of carbon dioxide (CO2) on global warming gained wide attention. Previous researches mainly focus on relationship between global average CO2 concentrations and surface air temperature (SAT).

Influence of Rossby waves on primary production from a coupled physical-biogeochemical model in the North Atlantic Ocean [PDF]

open access: yesOcean Science, 2008
Rossby waves appear to have a clear signature on surface chlorophyll concentrations which can be explained by a combination of vertical and horizontal mechanisms.

Interdecadal Change in Summer Extreme Rainfall Over North China Around the Early 2000s: Drivers and Mechanisms

open access: yesAtmospheric Science Letters, Volume 27, Issue 6, June 2026.
A discernible interdecadal change in extreme rainfall happened around the early 2000s, transitioning to a wetter period characterized by increased mean values and accelerated trends. The increased extremes were led by a poleward‐shifted East Asian westerly jet (lifting) and a strengthened and extended subtropical high (moisture transport), with little ...

Performance of the operational ECMWF ensemble in predicting heavy rain associated with the Emilia‐Romagna flood in May 2023

open access: yesWeather, Volume 81, Issue 6, Page 172-177, June 2026.
A devastating flood occurred in May 2023 in the Emilia‐Romagna region in northern Italy after 2 days with widespread accumulated precipitation exceeding 150mm. The event was associated with a quasi‐stationary upper‐level cutoff cyclone. This study investigates the performance of the operational ECMWF ensemble prediction system in capturing the cutoff ...

Missing Summer Westerly Jet Barotropic Governor Effect Explains Climate Models—Observation Discrepancies in the Indian Monsoon Trends

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The South Asian summer monsoon has exhibited a pronounced Northwest India‐Indo‐Gangetic Plains rainfall dipole since 1999, with northwest India experiencing a 24.6% increase, while rainfall in the Indo‐Gangetic Plain has decreased by 4.4%.

Rossby waves with bottom topography [PDF]

open access: yes, 1966
A simple analysis shows the analogy between Rossby waves and waves caused by irregularities in the depth of a homogeneous layer of fluid in a rotating system. The effect of bottom topography is shown to be very important in generating low-frequency waves

Characteristics of Kelvin waves and Mixed Rossby-Gravity waves in opposite QBO phases

open access: yes, 2017
A 35-year ERA-Interim dataset from the European Center for Medium-Range Weather Forecasts (ECMWF) was used to study the characteristics of Kelvin waves and Mixed Rossby-gravity waves based on a Space-Time Spectral Analysis (STSA).

The Dynamics of Magnetic Rossby Waves in the Quasigeostrophic Shallow Water Magnetohydrodynamic Theory

open access: yesThe Astrophysical Journal
The dynamics of magnetic Rossby waves are investigated by applying a quasigeostrophic shallow water magnetohydrodynamic system, which is linearized with respect to both uniform background flow and uniform magnetic field.
