                         infrared imagery over the Amazon region during 2014 and 2015. A 
                         total of 116,701 convective systems were identified and statistics 
                         on the probability of occurrence of track area, lifetime, and 
                         system velocity were analysed. Maps of the total and seasonal 
                         geographic density of trajectories and the geographic density of 
                         clusters at genesis, during propagation, and at dissipation were 
                         also assessed. The mean area and lifetime of the tracked systems 
                         was 4 x 10(4) km(2) and 3 hr, respectively. The top 10% largest 
                         systems had areas >8 x 10(4) km(2) and the top 10% longest lived 
                         systems lasted >7 hr. The geographical distribution of clusters 
                         identified on the coast and within the Amazon basin varied 
                         seasonally and their life cycle tracking showed that they are 
                         typically distinct from one another (i.e., it is relatively rare 
                         for systems to start at the coast and propagate 1,500 km to the 
                         centre of the basin). Although the average system velocity 
                         indicated a predominantly westward motion, a large spread in the 
                         direction of propagation was found. In particular, the probability 
                         of a meridional component of motion was generally the same for 
                         northward or southward directions and 35% of the zonal propagation 
                         was associated with eastward movement. The presence of Kelvin 
                         waves accounted for some of the eastward system motion, in 
                         addition to increasing the area and lifetime of storms compared to 
                         when Kelvin waves were not present.",
