File Information

Import time series of climate teleconnection indices from the United States National Weather Service (NWS)/National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center (CPC) website found here:

Downloadable indices include:
get_ao retrieves Arctic Oscillation (AO), sometimes called the Northern Annular Mode (NAM).

get_aao retrieves Antarctic Oscillation (AAO), sometimes the Southern Annular Mode (SAM).

get_nao retrieves North Atlantic Oscillation (NAO).

get_pna retrieves Pacific North-American Pattern.


OUTPUTS: (example for the AAO)
aao_ind = daily AAO index values
aao_dates = date vector

[aao_ind,aao_dates] = get_aao;
plot([aao_dates(1) aao_dates(end)],[0 0],'k'); hold on
xlim([aao_dates(1) aao_dates(end)])
box off
text(0,.9,' Antarctic Oscillation Index','units','normalized')
