Tropical monsoons in Indonesia and floods in the United States are both provoked by the Madden-Julian oscillation (MJO), a process that results in pulses of clouds and precipitation moving eastward around the globe at about 5 meters per second. Despite the MJO's importance, global models often struggle to simulate the oscillation accurately. Researchers showed that MJO simulations are most sensitive to the existence of lower level heating in the atmosphere.
