Abstract Quasi‐biennial oscillations (QBOs) in thirteen atmospheric general circulation models forced with both observed and annually repeating sea surface temperatures (SSTs) are evaluated. In most the QBO period is close to, but shorter than, of 28 months. Amplitudes within ±20 % amplitude at 10 hPa, typically about half that lower altitudes (50 70 hPa). For almost all models, oscillation's profile shows an overall upward shift compared to reanalysis its meridional extent too narrow....
Abstract. The Stratosphere–troposphere Processes And their Role in Climate (SPARC) Quasi-Biennial Oscillation initiative (QBOi) aims to improve the fidelity of tropical stratospheric variability general circulation and Earth system models by conducting coordinated numerical experiments analysis. In equatorial stratosphere, QBO is most conspicuous mode variability. Five have therefore been designed (i) evaluate compare verisimilitude modelled QBOs under present-day conditions, (ii) identify...
Abstract We compare the response of Quasi‐Biennial Oscillation (QBO) to a warming climate in eleven atmosphere general circulation models that performed time‐slice simulations for present‐day, doubled, and quadrupled CO 2 climates. No consistency was found among QBO period response, with decreasing by 8 months some lengthening up 13 others doubled simulations. In simulations, reduction 14 models, whereas several tropical oscillation no longer resembled present‐day QBO, although it could...
Abstract We analyze the stratospheric waves in models participating phase 1 of Stratosphere–troposphere Processes And their Role Climate (SPARC) Quasi‐Biennial Oscillation initiative (QBOi).

Abstract Since May 2022, the Mediterranean Sea has been experiencing an exceptionally long marine heatwave event. Warm anomalies, mainly occurring in Western basin, have persisted until boreal spring 2023, making this event longest heat wave of last four decades. In work, 2022/2023 anomaly is characterized, using in-situ and satellite measurements, together with state art reanalysis products. The role atmospheric forcing also investigated; onset growth sea surface temperature anomalies found...
Abstract The Quasi‐Biennial Oscillation initiative (QBOi) is a model intercomparison programme that specifically targets simulation of the QBO in current global climate models. Eleven models or versions participated QBOi study have upper boundaries above mesosphere and therefore simulate region where stratopause semiannual oscillation (SAO) dominant mode variability zonal winds tropical stratosphere. Comparisons SAO simulations these are presented here. These show amplitudes phases...

O is a secondary pollutant with adverse effects on population health ecosystems negative climate, acting as greenhouse gas. Most these focused spring 2020 (i.e. March–May) observations in planetary boundary layer (PBL), mostly vicinity urban agglomerates. Here, we analyzed...
Abstract The Quasi-Biennial Oscillation (QBO) and the El Niño–Southern (ENSO) are two dominant modes of climate variability at Equator. There exist observational evidences mutual interactions between these phenomena, but this possibility has not been widely studied using model simulations. In work we assess how current models represent ENSO/QBO relationship, in terms response amplitude descent rate stratospheric wind regimes, by analyzing atmosphere-only ocean–atmosphere coupled simulations...
Abstract. This study uses an ensemble of climate model experiments coordinated by the Quasi-Biennial Oscillation initiative (QBOi) to analyze Madden-Julian (MJO) in presence either perpetual El Niño or La Niña sea surface temperatures during boreal winter. In addition prescribed Southern (ENSO) conditions, nine models internally generate QBOs, meaning each may influence MJO. The diagnostics used include wavenumber-frequency spectra tropical convective and dynamical fields, measures MJO...
Abstract. This study examines Quasi-Biennial Oscillation (QBO) teleconnections and their modulation by the El Niño-Southern (ENSO), using a multi-model ensemble of Atmospheric Processes And Role in Climate (APARC) QBO initiative (QBOi) models. Some difficulties arise examining observed QBO-ENSO from distinguishing ENSO influences outside region, due to aliasing between over historical record. To separate signals, simulations are conducted with annually-repeating prescribed sea-surface...
Abstract Observational records are more often than not influenced by residual non‐climatic factors which must be detected and adjusted for prior to their usage. In this work, we present a novel approach, named Radiosounding HARMonization (RHARM), providing homogenized data set of temperature, humidity wind profiles along with an estimation the measurement uncertainties 697 radiosounding stations globally. The RHARM method has been used adjust twice daily (0000 1200 UTC) radiosonde holdings...
Nowadays, there is growing interest in applying artificial intelligence (AI) on board Earth observation (EO) satellites for time-critical applications, such as natural disaster response. However, the unavailability of raw satellite data currently hinders research lightweight preprocessing techniques and limits exploration end-to-end pipelines, which extract insights directly from source data. To fill this gap, work presents a novel methodology to automate creation datasets detection target...

Under such conditions, phytoplankton communities modify their structure functions, resilience is not assured. This study characterizes the impact MHWs on spring bloom in North‐Western Mediterranean Sea. Here, we synergistically combine autonomous observations from BioGeoChemical‐Argo floats, satellite‐based ecosystem model data, show MHW events...

The Copernicus Climate Change Service (C3S) has been actively grappling with how build such trust: provision demonstrably independent assessments quality products, which was deemed an important element trust-building processes. C3S provides access essential variables (ECVs) from multiple...
Abstract The general circulation of the middle atmosphere, particularly mesosphere, is strongly dependent on forcing arising from gravity wave processes. Their sources in troposphere are both orographic and nonorographic, latter being intermittent. In climate models, effects waves need to be parameterized, often assuming that their properties constant. this work we focus changes atmosphere due introduction intermittency a parameterization nonorographic waves, using stochastic version Hines...
Abstract The simulated stratospheric dynamics have been improved compared to previous generations in many climate models taking part the Coupled Model Intercomparison Project Phase 6 (CMIP6). This was achieved by going from low high‐top configurations, that is, increasing atmospheric vertical resolution, raising model lid height and including parameterization schemes, such as non‐orographic gravity wave drag (GWD), simulate small‐scale processes. also applies EC‐Earth model, for which...
