摘要:The atmosphere can self‐organize into long‐lasting large‐scale overturning circulations over an ocean surface with uniform temperature. This phenomenon is referred to as convective self‐aggregation and has been argued to be important for tropical weather and climate systems. Here we present a boundary layer centric framework based on the available potential energy budget of convective self‐aggregation. We show that boundary layer diabatic processes dominate the available potential energy production and are, therefore, essential to convective self‐aggregation. We further show that the enhanced virtual effect of water vapor can lead to convective self‐aggregation.
