Short Summary

This study investigates the impact of three-dimensional shortwave radiation on cloud condensate, size, and lifetime using large-eddy simulations coupled to an interactive land surface model. The results show that 3D radiation produces larger and longer-lived clouds compared to one-dimensional radiation.

Objective

• Investigate the effects of three-dimensional shortwave radiation on cloud properties

Study Configuration

• Spatial Scale: Global scale, with a focus on cloud formation and evolution
• Temporal Scale: Simulations were run over a period of several days to capture cloud development and lifetime

Methodology and Data

• Models used: Large-eddy simulations coupled to an interactive land surface model (LSM)
• Data sources: No specific data sources mentioned, but likely relies on reanalysis or observational datasets for validation

Main Results

• 3D radiation produces higher cloud tops and greater cloud condensate than 1D radiation
• Enhanced radiative flux leads to increased surface temperature, amplifying sensible and latent heat fluxes beneath clouds by about 40%
• 3D radiation produces larger and longer-lived clouds compared to 1D radiation

Contributions

• This study provides new insights into the role of three-dimensional shortwave radiation in cloud formation and evolution, highlighting its importance for accurately simulating cloud properties
