Abstract: The Lagrangian transport of particles and its role in the redistribution of moisture and rainfall in a monsoonlike flow is investigated using a simple, dynamically consistent model of the heat-induced tropical circulation. ...

Abstract: Maximum stretching lines in the lower stratosphere around the Antarctic polar vortex are diagnosed using a method based on finite-size Lyapunov exponents. By analogy with the mathematical results known for simple dynamical ...

Abstract: A plausible mechanism for the formation of mixing layers in the lower stratosphere above regions of tropical convection is demonstrated numerically using high-resolution, two-dimensional (2D), anelastic, nonlinear, ...

Abstract: Variability of flow regimes and turbulence scalings in a model of an inhomogeneously stratified, tropopause jet is investigated through high-resolution, forced, three-dimensional numerical simulations (with 512 or 1024 ...
