热带地区有组织的对流发生在一系列的空间和时间尺度上，并强烈影响云量和湿度。组织的一种模式是“自聚集”，其中湿对流自发地组织成一个或几个孤立的集群，尽管空间均匀的边界条件和强迫。自聚集是由云、水分、辐射、地表通量和环流之间的相互作用驱动的，并且发生在各种各样的辐射-对流平衡的理想化模拟中。本文对数值模拟中的对流自聚集现象进行了综述，包括其特征、原因和影响。我们描述了自聚集的演变，包括它的时间和长度尺度以及导致其触发和维持的物理机制，我们还讨论了与气候和气候变化的可能联系。
Organized convection in the tropics occurs across a range of spatial and temporal scales and strongly influences cloud cover and humidity. One mode of organization found is “self-aggregation,” in which moist convection spontaneously organizes into one or several isolated clusters despite spatially homogeneous boundary conditions and forcing. Self-aggregation is driven by interactions between clouds, moisture, radiation, surface fluxes, and circulation, and occurs in a wide variety of idealized simulations of radiative–convective equilibrium. Here we provide a review of convective self-aggregation in numerical simulations, including its character, causes, and effects. We describe the evolution of self-aggregation including its time and length scales and the physical mechanisms leading to its triggering and maintenance, and we also discuss possible links to climate and climate change.
