    Extreme anomalies under El Niño and La Niña developing tendencies restrain subsequent severe typhoons in the western North Pacific by Rong Fang, Shumin Chen, Weibiao Li, Mingsen Zhou, Aoqi Zhang, Yilun Chen

    Published 2022-08-01
    “…The reason for this classification is that the air‒sea conditions were different when the oceanic phenomena developed toward an El Niño or La Niña phase during the previous year, and the results of these trends affect the subsequent features of atmospheric dynamic factors favorable for TC development (relative vorticity and vertical velocity). …”

    Breeding and predictability in the baroclinic rotating annulus using a perfect model by Young, R, Read, P

    Published 2008
    “…This behaviour is studied in the Met Office/Oxford Rotating Annulus Laboratory Simulation - a model of the classic rotating annulus laboratory experiment with differentially heated cylindrical sidewalls, which is firmly established as an insightful laboratory analogue for certain kinds of atmospheric dynamical behaviour. This work is the first study of "predictability of the first kind" in the annulus experiment. …”

    The non‐conservation of potential vorticity by a dynamical core compared with the effects of parametrized physical processes by Saffin, L, Methven, J, Gray, S

    Published 2016
    “…This ‘PV tracer technique’ is used to accumulate separately the effects on PV of each of the different non‐conservative processes represented in a numerical model of the atmosphere. Dynamical cores are not exactly conservative because they introduce, explicitly or implicitly, some level of dissipation and adjustment of prognostic model variables which acts to modify PV. …”

    Extratropical low-frequency variability in a three-level quasi-geostrophic atmospheric model with different spectral resolution by Weisheimer, A, Kurgansky, M, Dethloff, K, Handorf, DR

    Published 2003
    “…Apart from variations of external forcing components and interactions between climate subsystems, natural atmospheric fluctuations with periods of years, decades and centuries can also be generated by inherent atmospheric dynamical instabilities of the flow. The objective of this study is to investigate the spatial and temporal structure of internal low-frequency atmospheric variability of the Northern Hemisphere using a minimum-complexity model of the extratropical circulation. …”

    Impacts of Aeolus horizontal Line‐Of‐Sight (HLOS) wind assimilation on the Korean integrated model (KIM) forecast system by Sihye Lee, Hyo‐Jong Song, In‐Hyuk Kwon, Jeon‐Ho Kang

    Published 2023-03-01
    “…Abstract The Korean Integrated Model (KIM) forecast system, based on a hybrid four‐dimensional ensemble‐variational method, was extended to assimilate Horizontal Line‐Of‐Sight (HLOS) wind observations from the Atmospheric Laser Doppler Instrument (ALADIN) on board the Atmospheric Dynamic Mission Aeolus satellite. In a global cycling experiment, assimilation of Aeolus HLOS wind observations led to reductions in the average root‐mean‐square error of 0.8 and 0.5% for the zonal and meridional wind analyses when compared against European Center for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecast System (IFS) analyses. …”

    Published 2024-02-01
    “…The comparison between the models with high PDO skill and low PDO skill shows that the PDO-related sea surface temperature (SST) gradient between the western and central tropical Pacific plays an important role in changing the large-scale atmospheric dynamic fields for TC genesis and, thus, the TCF over the WNP. …”
