This weighting does not apply to the sign agreement calculation. Multimodel ensemble mean of the pattern correlation in Taylor statistics is calculated via Fisher z-transformation and back transformation. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue record: - Link to the report component containing the figure (Chapter 3) - Link to the Supplementary Material for Chapter 3, which contains supporting information on the figure in Section and details on the input data used in Table 3.SM.1 - Link to the code for the figure, archived on Zenodo - Link to the figure on the IPCC AR6 website Phillips, Adam Unavailable author Unavailable author Kosaka, Yu Unavailable author Unavailable author Cassou, Christophe Unavailable author Unavailable author Kazeroni, Rémi Unavailable author Unavailable author NERC EDS Centre for Environmental Data Analysis custodian 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk custodian NERC EDS Centre for Environmental Data Analysis distributor 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk distributor NERC EDS Centre for Environmental Data Analysis point_of_contact 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk pointofContact NERC EDS Centre for Environmental Data Analysis publisher 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk publisher notPlanned dataset IPCC-DDC IPCC AR6 WG1 WGI Sixth Assessment Report Working Group I Physical Science Basis Chapter 3 Human influence large-scale indicators Natural variability anthropogenically-forced change observed changes Figure 3.33 Annular Modes NAM SAM NAO modes of variability CMIP5 CMIP6 atmospheric conditions theme GEMET - INSPIRE themes, version 1.0 2008-06-01 publication otherRestrictions Public data: access to these data is available to both registered and non-registered users. otherRestrictions Under the following licence http://creativecommons.org/licenses/by/4.0/, appropriate use of these data may fall under any use.
