热带地区有组织的对流发生在一系列空间和时间尺度上，并强烈影响云量和湿度。发现的一种组织模式是“自聚集”，在这种模式下，湿对流自发地组织成一个或几个孤立的星团，而不考虑空间上均匀的边界条件和强迫。自聚集是由云、水汽、辐射、地表通量和环流之间的相互作用驱动的，并出现在各种理想的辐射对流平衡模拟中。本文对数值模拟中的对流自聚集现象进行了综述，包括对流自聚集的特征、成因和↵等。我们描述了自聚集的演化，包括它的时间和长度尺度，以及导致它触发和维持的物理机制，并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 radiativeconvective equilibrium. Here we provide a review of convective self-aggregation in numerical simulations, including its character, causes, and e↵ects. 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.
