The ERA‐40 data set is used to examine the equatorial quasi‐biennial oscillation (QBO). extends from ground 0.1 hPa (∼65 km) and covers a 44‐year period (January 1958 December 2001), including 18.5 QBO cycles. Analysis of this unprecedented spatial temporal coverage has revealed threefold structure in height zonal wind anomalies at equator. In addition well‐known twofold lower middle stratosphere, that is, easterlies overlying westerlies or vice versa, there third anomaly upper stratosphere....
Abstract The interaction of the 11-yr solar cycle (SC) and quasi-biennial oscillation (QBO) their influence on Northern Hemisphere (NH) polar vortex are studied using idealized model experiments ECMWF Re-Analysis (ERA-40). In experiments, sensitivity NH to imposed easterlies at equatorial/subtropical latitudes over various height ranges is tested explore possible from zonal wind anomalies associated with QBO SC in those regions. show that timing modeled stratospheric sudden warmings (SSWs)...
Abstract. Numerical simulation, and in particular simulation of the earth system, relies on contributions from diverse communities, those who develop models to involved devising, executing, analysing numerical experiments. Often these people work different institutions may be working with significant separation time (particularly analysts, data produced years earlier), they typically communicate via published information (whether journal papers, technical notes, or websites). The complexity...
The introduction of FAIR data practices into the assessment process Intergovernmental Panel on Climate Change (IPCC) enhances transparency Assessment Reports (ARs). approach focuses figure creation and reproducibility figures within reports. creating for IPCC reports makes it particularly challenging to credit all contributors. A single can incorporate from observations, models, publications, originating numerous sources generated by multiple authors, each contributing different parts...

A full troposphere‐stratosphere‐mesosphere global circulation model is used in a set of idealised experiments to investigate the sensitivity Northern Hemisphere winter stratospheric flow improvements equatorial zonal winds. The shows significant variability upper stratosphere, imposition SAO and QBO like this region advances timing midwinter sudden warmings by about one month. Perturbations lower stratosphere are mainly found influence early polar variability. These results suggest that it...
Abstract. The Metafor project has developed a common information model (CIM) using the ISO19100 series formalism to describe numerical experiments carried out by Earth system modelling community, models they use, and simulations that result. Here we mechanism which CIM was developed, its key properties. We introduce conceptual application versions controlled vocabularies in context of supporting fifth Coupled Model Intercomparison Project (CMIP5). how been used coupling properties near term...
Abstract. Earth system modelling relies on contributions from groups who develop models and those involved in devising, executing, exploiting numerical experiments. Often these people work different institutions, they may communicate primarily via published information (whether journal papers, technical notes, or websites). The complexity of the models, experiments, methodologies, along with diversity (and sometimes inexact nature) sources can easily lead to misinterpretation what was...
The signature of mid‐latitude convection observed by a 46.5 MHz wind‐profiling radar at Aberystwyth, UK (52.4°N, 4.0°W), is demonstrated way case study. A key feature such radars their ability to measure the vertical air velocity directly, even under conditions precipitation. Higher frequency radars, which have more typically been used for studies, net effect hydrometeor terminal velocities and motion conditions. capable observing both updrafts downdrafts, with peak order 10 m s −1 ....
Abstract. There are three key components for developing a metadata system: container structure laying out the semantic issues of interest and their relationships; an extensible controlled vocabulary providing possible content; tools to create manipulate that content. While systems must allow users enter own information, use both imposes consistency definition ensures comparability objects described. Here we describe (CV) creation tool built by METAFOR project in context describing climate...
Abstract The stratospheric sudden warming in the Southern Hemisphere (SH) September 2002 was unexpected for two reasons. First, planetary wave activity is very weak, and midwinter warmings have never been observed, at least not since observations of upper stratosphere became regularly available. Second, occurred a west phase quasi-biennial oscillation (QBO) lower stratosphere. This because are usually considered to be more likely east QBO, when zero wind line present winter subtropics hence...

Many of the figures in WGI contribution to IPCC Sixth Assessment report (AR6) are derived from data multiple CMIP6 simulations.  For instance, a plot showing projections global temperature change Figure 2 Chapter 4 AR6 is based on 183 simulation datasets.

The Sixth Assessment Report (AR6) marked the first time that Intergovernmental Panel on Climate Change (IPCC) recommended and implemented FAIR data principles as part of assessment process. While critical importance utility are widely acknowledged, their implementation is not straightforward, especially in this unique context involves collaboration hundreds scientists around world from different disciplines, utilising diverse information sources. We describe challenges lessons learned when...
<p>The Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC) have provided scientific basis underpinning far reaching policy decisions.The reports also a huge influence public debate about climate change. The IPCC is not responsible either for evaluation data and related emissions socioeconomic scenarios or provision advice (reports must be “neutral, policy-relevant but policy-prescriptive”). These omissions may appear...
