Boundary Layer Formation in the Quasigeostrophic Model Near Nonperiodic Rough Coasts

Singular front formation in a model for quasigeostrophic flow

A two-dimensional model for quasigeostrophic flow which exhibits an analogy with the three-dimensional incompressible Euler equations is considered. Numerical experiments show that this model develops sharp fronts without the need to explicitly incorporate any ageostrophic effect. Furthermore, these fronts appear to become singular in finite time. The numerical evidence for singular behavior su...

Increasing ozone in marine boundary layer inflow at the west coasts of North America and Europe

An effective method is presented for determining the ozone (O3) mixing ratio in the onshore flow of marine air at the North American west coast. By combining the data available from all marine boundary layer (MBL) sites with simultaneous wind data, decadal temporal trends of MBL O3 in all seasons are established with high precision. The average springtime temporal trend over the past two decade...

Boundary Layer Leakage Model

This paper presents a model for gas leakage that takes the development of the velocity profile into account. It includes the physical ideas behind the model, a brief discussion of the mathematical approach and a comparison with experimental data.

Kinetic dendrite in the boundary-layer model

Within trie boundary-layer model and by taking into account only interface kinetics (isotropic or anisotropic), we find a contmuous set of « kinetic » dendrites. This solution exists at arbitrary supercooling A in the 2Dand 3D-axisymmetric cases and reduces to the usual dendrites with parabolic tails at A ~ l, and « angular » dendrites at A ~ l. In contrast with classical Ivantsov dendrites, th...
