| Zusammenfassung |
| For the classification of the synoptic processes in the tropical Pacific
using daily data, criteria were proposed for identifying the different
evolutional phases of the equatorial westerly wind zone. The criteria are
based on the location, extent and activity of the westerly wind zone on the
850 hPa isobaric surface. According to this classification all the observed
variants of the westerly wind regime above the tropical Pacific can be
divided into three classes: normal, active, and break. For each class one
specific pattern of tropical atmospheric circulation centers and divergent
wind velocity potential in the lower and upper troposphere are found.
Using the singular value decomposition method (SVD) the connection between
the atmospheric circulation and sea surface temperature (SST) of equatorial
Pacific is investigated. |
