Halaman: 25 - 42 One important aspect when its coupling processes equatorial atmosphere (CPEA) Campaign 2004 in kototabang which lasted for approximately one month of observation (Apil 10 to May 10 2004) was an analysis of the vertical structure of the phenomenon of the maddenjulian Oscilasion (MJO) related to the activity of the super cloud clusters (SCCS) as one of the main parameters in assessing the behavior of rainfall occurred in the wastern region of indonesia. The data used are data of Equatorial Atmosphere Radar (EAR) Boundary Layer Rader (BLR) Mini Automatic Weather Station (MAWS) and optical Rain Gauge (ORG) at kototabang LAPAN Ground Station. While the supporting data used are long-wave radiation anomaly data (Outgoing Longwave Radiation OLR) and surface rainfall data. The analysis using spectral techniques particularly the Fast Fourier Transform (FFT) on data anomalies daily average five (pented) ORL oscillation 2001-2005 period shows that the doninant than the data is approximately 30 daily. Thise oscillations typically occured in the lower troposphere layer with the direction of propagation toward the east. Besides that the exsistence of convergence and divergence processes in the layer 3 and 10 km above mean sea level (mls) is also found particularly on the date April 23 2004 of EAR data analysis. Finlly we try to link these events by analyzing the relationship between OLR with the rainfall in kototabang and the surronding region particularli ORG measurement results with the correlation coefficient of about 0.71.
