Convective aggregation in realistic convective‐scale simulations

Convective aggregation in realistic convective-scale simulations

To investigate the real-world relevance of idealized-model convective self-aggregation, five 15 day cases of real organized convection in the tropics are simulated. These include multiple simulations of each case to test sensitivities of the convective organization and mean states to interactive radiation, interactive surface fluxes, and evaporation of rain. These simulations are compared to se...

The sensitivity of convective aggregation to diabatic processes in idealized radiativeconvective equilibrium simulations

Idealized explicit convection simulations of the Met Office Unified Model exhibit spontaneous selfaggregation in radiative-convective equilibrium, as seen in other models in previous studies. This selfaggregation is linked to feedbacks between radiation, surface fluxes, and convection, and the organization is intimately related to the evolution of the column water vapor field. Analysis of the b...

Analysis of updraft velocity in mesoscale convective systems using satellite and WRF model simulations

Updraft vertical velocity is an important dynamical quantity which is strongly related to storm intensity and heavy precipitation. It can be calculated by direct observations, NWP model, and geostationary satellites which can provide the possibility of measuring this quantity with high temporal resolution. This research analyzed updraft velocity based on six derived parameters from INSAT3-D and...

Insights Gained from Realistic Simulations

This chapter discusses the insights gained from simulations using realistic propagation model. Speci cally the performance in terms of coverage and achievable bit rates, and topologies formed are dealt with. It is shown that the topologies formed in mesh networks pave way for development of new protocols. Speci cally, an e cient paging protocol for urban mesh network setting is developed that m...
