Madden Julian Oscillation (MJO) is defined as eastwards propagation of rainfall from the Indian Ocean to the western pacific ocean with an average velocity of 5ms. To study the existence of such oscillation over a low latitude station Hyderabad (17.366°Nand 78.476°E) the parameters pressure and precipitation are chosen. Pressure and precipitations values are evaluated from the Radiosonde data of Hyderabad station, collected from the Integrated Global Radiosonde Archive, NOAA. The missing values of data are interpolated by using Matlab tools. Finally, the variations of pressure and precipitation values are plotted with respect to time in days. Hence it is found that the pressure and precipitation are fluctuating with the frequency of MJO (frequency of MJO is 7 to 8 per annum) which is clear evidence of the existence of MJO over Hyderabad. This research is very useful for weather forecasting, air traffic control, and the agriculture sector,
