Abstract
The interaction of the atmosphere-land- ocean in the Asian monsoon and monsoon regions of Australia and the Pacific Ocean one of which generate annual variability of climatic elements in the region that became known as the TBO. TBO (Tropospheric Biennial Oscillation) is one form of annual climatic element variations in the troposphere (from the surface to the tropopause) with a period of about 2-3 years is happening in the Asian monsoon region, the Australian monsoon, tropical Indian Ocean and tropical Pacific Ocean. Asian summer monsoon mechanism and El nino Southern Oscillation (ENSO) system is commonly expressed in the schema-atmosphere-ocean monsoon (Monsoon- Ocean-Atmosphere System, Maos). The data used in this study consisted of rainfall data and the average monthly temperature, the observation period 1971-2013 in Class I Geophysical station of Bandung. The method used to identify the influence of ENSO on rainfall patterns and temperature, using wavelet analysis. The results of data processing and analysis indicate that precipitation and temperature in Bandung is not affected by ENSO but the dominant influence of the monsoon or annual cycles and cycles of local influence
