AB: Current convective parameterizations are often quite successful at simulating the mean properties of convective rainfall. However, they are generally less successful at simulating aspects of tropical rainfall variability, such as convectively coupled waves and the the Madden Julian Oscillation. I will discuss the development of a new convective parameterization. Attention will be given to its ability to simulate the diurnal behaviour of rainfall and mid-tropospheric relative humidity over the tropical oceans.
