对澳大利亚西北部两个云团的比较研究突出了天气对热带气旋发生的影响。虽然两个集群都在同一地区的陆地上发展，但大尺度气流有利于一个集群发展为热带气旋Enid，而抑制了另一个集群的发展。非发展低压位于对流层高压脊的强高空东风下方。副热带西风的高空槽后来分裂了脊线，为低层季风槽带来了光线和发散的高空风。这促进了低层气旋环流的发展和加强，即热带气旋伊妮德。
A comparative study of two cloud clusters in the north-west of Australia highlights synoptic influences on tropical cyclogenesis. Although both clusters developed over land in the same region, the large-scale flow was conducive to the subsequent development of one cluster into tropical cyclone Enid and suppressed the development of the other cluster. The non-developing low was under strong upper easterlies from an upper tropospheric ridge. An upper trough in the subtropical westerlies later split the ridge, bringing light and divergent upper winds over the low-level monsoonal trough. This facilitated the development and intensification of a low-level cyclonic circulation, tropical cyclone Enid.
