The QBO in WACCM4 is prescribed by relaxing equatorial zonal winds between 86 and 4 hPa to observed radiosonde data (28 - month period).

The quasi-biennial oscillation (QBO) in the equatorial zonal wind is an outstanding phenomenon of the atmosphere.

This variation is characterized by zonally uniform phase changes and is strongly coupled with the quasi-biennial oscillation of the equatorial zonal wind in the lower stratosphere.

Inter-Tropical Convergence Zone (ITCZ)- The Inter-Tropical Convergence Zone is an equatorial zonal belt of low pressure near the equator where the northeast trade winds meet the southeast trade winds.

However, if one downweights these two events (either by eliminating or, as in Cane et al» 97, using a «robust» trend), then an argument can be made for a long - term pattern which is in some respects more «La Nina» - like, i.e. little warming in the eastern and central equatorial Pacific, and far more warming in the western equatorial Pacific and Indian oceans, associated with a strengthening, not weakening, of the negative equatorial Pacific zonal SST gradient.

The regular oscillation of ENSO in g1 is associated with its unsuccessful representation of the role of atmospheric noise over the western — central equatorial Pacific (WCEP) in triggering ENSO events, which arises from the weak synoptic — intraseasonal variability of zonal winds over the WCEP in g1.

Interactions between externally - forced climate signals from sunspot peaks and the internally - generated Pacific Decadal and North Atlantic Oscillations «When the PDO is in phase with the 11 year sunspot cycle there are positive SLP anomalies in the Gulf of Alaska, nearly no anomalous zonal SLP gradient across the equatorial Pacific, and a mix of small positive and negative SST anomalies there.

The zonal component of the winds in the stratosphere above equatorial and tropical regions is, in the mean, relatively weak.

Deeper zonal winds at different latitudes of the equatorial region are measured by tracking cloud features observed within hot spots on continuum - band images.

This high variability is attributed to the successive passages of a zonal salinity front, trapped in the (5 N 5 S) equatorial band and migrating in phase with the southern oscillation index.
