Numerical Simulation of Baroclinic Jovian Vortices [PDF]
, 1994 We examine the evolution of baroclinic vortices in a time-dependent, nonlinear numerical model of a Jovian atmosphere. The model uses a normal-mode expansion in the vertical, using the barotropic and first two baroclinic modes.

Improved Bayesian Network-Based Risk Model and Its Application in Disaster Risk Assessment
International Journal of Disaster Risk Science, 2018 The application of Bayesian network (BN) theory in risk assessment is an emerging trend. But in cases where data are incomplete and variables are mutually related, its application is restricted. To overcome these problems, an improved BN assessment model
