PlaSim CTL horizontal wind speed differences and vectors at 1000 hPa.

PlaSim CTL simulation. See if the wind speed differences respond to ENSO changes as shown in the AMIP-II SST anomalies in the Niño 3.4 region. We also compare our differences with ERA-Interim differences. We chose to pause time and spin around once for those key months in the development of the following ENSO strong phases ([ Ссылка ]):

1982-83 - very strong El Niño
1988-89 - strong La Niña
1997-98 - very strong El Niño
1999-00 - strong La Niña
2007-08 - strong La Niña
2010-11 - strong La Niña

Key months are those at the beginning (June), mid-way (December) and end (May) of the development of a typical ENSO phase.

All images were plotted using the Python modules Iris ([ Ссылка ]...) and cartopy ([ Ссылка ]...).

If it is too fast try slowing it down using YouTube settings.
