Research Details
Description: The axisymmetric version of CM1 was used in an attempt to recreate the tropical cyclone diurnal cycle (TCDC). A random Gaussian noise distribution was applied at the initial time to generate a suite of ten ensemble members. These members were averaged together to remove noise. Results focused on comparing the timing of the TCDC in the model to the observed timing of cirrus canopy expansion, overnight convection, precipitation, and intensity changes. The ensemble mean was used to study the underlying dynamics of the TCDC as portrayed by CM1. Sensitivity experiments related to domain size, microphysics scheme, latitude, cloud-radiative forcing, and radiation were performed.
Presenting results at the 8th Northeast Tropical Workshop and at the 18th Cyclone Workshop, respectively.
