Summary: | Author: Yvonne Anderson Contact: ee22ya@leeds.ac.uk Dataset created: 21/08/2023 Paper title: Minimal influence of future Arctic sea ice loss on North Atlantic jet stream morphology Dataset information CSV files contain arrays of daily jet feature data for all ensemble member winters for a given model. Dimensions of the arrays are (number of ensemble members, 90 winter days). Filename structure Filenames of CSV files can be interpreted as: timeperiod_jetfeature_model.csv Example filename structure Time period Jet feature Model Example filename Present-day Latitude AWI-CM-1-1-MR present-day_jet_latitude_AWI-CM-1-1-MR.csv Future Speed HadGEM3-GC31-MM future_jet_speed_HadGEM3-GC31-MM.csv Jet feature description Jet feature data are for the largest mass jet region found on each day of winter, where jet mass is the area weighted jet speed. The jet features and corresponding units contained in the csv files are as follows: Jet feature Units Latitude ° Speed ms-1 Mass ms-1 Tilt ° Area m2 Time periods Time periods are present-day and future, which refer to simulations forced by present-day and future sea ice concentrations, from which the jet features have been extracted. Models Models are AWI-CM-1-1-MR, CanESM5, FGOALS-f3-L, HadGEM3-GC31-MM, IPSL-CM6A-LR and MIROC6 from the Polar Amplification Model Intercomparison Project (PAMIP; https://doi.org/10.5194/gmd-12-1139-2019) Spatial and temporal information Arrays contain daily jet feature data that has been constrained to the North Atlantic region (0-60 ° W, 15-75 ° N) and to the winter period (December, January and February) Prior processing Original dataset: netcdf files of daily zonal wind data from Polar Amplification Model Intercomparison Project simulations forced by present-day and future sea ice concentrations 850 hPa wind speed data was extracted and regridded to 2.81 ° x 2.81 ° resolution Constrained to North Atlantic region and winter period Wind speed data was filtered using a 10-day Lanczos filter with a 61 day window Jet feature data was extracted for each ... |
