Stop using composites
Composites are bad. Use regressions instead.
Mini replication of "Subseasonal Vacillations in the [boreal] Winter Stratosphere"
Fun fitting a sine model
Comment on "A new zonal wave 3 index for the Southern Hemisphere"
How to measure a wave that is not just a wave.
Sources and impacts of the zonally asymmetric component of the Southern Annular Mode
Explanation of our recent paper on asymmetric and symmetric parts of the Southern Annular Mode.
Does the Southern Annular Mode exist?
Scavenging the literature on the Southern Annular Mode I came across two papers from the early 2000's which seem to question whether this mode is actually a global phenomenon and not a statistical artifact.
The meridional structure of the Semiannual Oscillation
How to filter out extra-tropical variabilty to highlight the structure of the Semiannual Oscillation using just multiple linear regression.
ENSO and regression to the mean
How a recent paper published in Nature was pray to regression to the mean.
Analysis of "Global wave number-4 pattern in the southern subtropical sea surface temperature."
A recent paper claims to have detected a global wave-4 pattern in subtropical SSTs. But have they really?
