    The scaling of CP expansion with potential energy furthermore may assist a better understanding of the kinetics and internal vortical circulation of CPs, which play a crucial role in the mechanical forcing during CP collisions (Cafaro & Rooney, 2018) and are important factors for CP dissipation (Grant & van den Heever, 2016, 2018; Romps ...

    Forced mechanical lifting through cold pool gust fronts can trigger new convection and, as previous work highlights, is enhanced when cold pools collide. However, as shown by conceptual models, the organization of the convective cloud field emerging from two versus three colliding cold pools differs …

    • A cold pool's initial potential energy is a good predictor of its spreading dynamics • Cold pool radii evolve as a combinationof two power laws, highlighting a dynamic transition induced by "lobe‐and‐cleft" instabilities • Updrafts and mass flux are strongly enhanced in multicold pool collisions compared to single cold pool ...

    For all environments tested, mechanical forcing peaked robustly at an optimal initial distance between the cold pools due to a balance between the creation and dissipation of kinetic energy, and ...

    These two dynamic regimes are characterized by two distinct power law exponents and explain the transition by the onset of "lobe‐and‐cleft" instabilities at the cold pool head, which may help decipher the role of cold pools in spatially organizing convection and precipitation. Forced mechanical lifting through cold pool gust fronts can trigger new convection and, as previous work ...

    Mechanical Forcing of Convection by Cold Pools: Collisions and Energy Scaling ... We find that cold pool expansion can be well described by initial potential energy alone. Cold pool expansion monotonically slows but shows an abrupt transition between an axisymmetric and a broken‐symmetric state mirrored by a sudden drop in expansion speed ...

    impact of the following four parameters on the mechanical and thermodynamic forcing associated with cold pool collisions: (1) the initial temperature perturbation of cold pools, (2) the initial distance between cold pools, (3) the environment in which cold pools exist, and (4) the strength of atmospheric diffusion.
