| Summary: | (zonal wavelength is 2,500-3,000 km). Composites over the 6,000 km) and 7 m/s eastward propagation of over Sahel Africa across the entire Pacific Ocean. Seven tropical regions are along convergence zones and in the west Pacific warm pool Amazon basin shows little preference of zonal direction. and Indian Ocean regions. Hovmoller plots of synoptically anomalies between warm and cold ENSO phases in the Pacific anomalies that can often be tracked around the globe. The anomalies, while PW anomalies remain coherent throughout the behavior. Hovmoller composites reveal 10 m/s westward chosen to perform climatological studies of synoptic scale correlation between PW and OLR data over the tropical domain demonstrate both eastward or westward propagation according directional reversal of zonal propagation of synoptic PW each hemisphere. Hovmoller composites suggest an additional eastward propagating mode between 5ON and 12.50N during SON filtered OLR and PW data show large regions void of OLR filtered precipitable water (PW) estimated from TOVS found to be poorly correlated with each other. Time-longitude Interaction between the synoptic and the intraseasonal and interannual time scales is studied. The intraseasonal operational satellite observations for 24 three-month oscillation does not affect synoptic PW anomalies, even plots (Hovmoller format) identify spatially coherent PW propagation across northern hemisphere Africa. Other regions propagation across the North Atlantic (zonal wavelength is propagation in the ITCZ, SPCZ, west Pacific warm pool, and region, implying the PW is both a more sensitive and a more regions of enhanced synoptic variance are quantified and reliable signal. seasons. Zonally-oriented tropical convergence zones and shows weak negative correlation, with almost zero correlation southern Indian Ocean suggest westward motion, while strongest and most consistent signal is of eastward to season and location. A general shift from eastward to Tropical synoptic scale behavior is examined using 3 to 8 day tropics. A seasonally averaged daily point-to-point westward propagation occurs between 200 and 300 latitude in within the monsoon regions. Lag correlation plots reveal a |
