Query: Comparing Convective Self-Aggregation in Idealized Models to Observed
  Moist Static Energy Variability near the Equator   Idealized convection-permitting simulations of radiative-convective
equilibrium (RCE) have become a popular tool for understanding the physical
processes leading to horizontal variability of tropical water vapor and
rainfall. However, the applicability of idealized simulations to nature is
still unclear given that important processes are typically neglected, such as
lateral vapor advection by extratropical intrusions, or interactive ocean
coupling. Here, we exploit spectral analysis to compactly summarize the
multi-scale processes supporting convective aggregation. By applying this
framework to high-resolution reanalysis data and satellite observations in
addition to idealized simulations, we compare convective-aggregation processes
across horizontal scales and data sets. The results affirm the validity of the
RCE simulations as an analogy to the real world. Column moist static energy
tendencies share similar signs and scale-selectivity in convection-permitting
models and observations: Radiation increases variance at wavelengths above
1,000km, while advection damps variance across wavelengths, and surface fluxes
mostly reduce variance between 1,000km and 10,000km.
