Abstract We report temperature cross correlation and velocity profile measurements in the aspect-ratio-one convection cell filled with water. A sharp transition from a random chaotic state to a correlated turbulent state of finite coherence time is found when the Rayleigh number becomes larger than a critical value Ra{sub c}{approx_equal} 5 x 10{sup 7} . The experiment reveals a unique mechanism for the onset of coherent oscillations in turbulent Rayleigh-Benard convection.
