A three dimensional numerical interpolation scheme which resolves frontal gradients with fidelity was developed. The scheme is applied to the study of atmospheric upper baroclinic zones.
A three dimensional numerical interpolation scheme which resolves frontal gradients with high fidelity was developed and is being applied to the study of atmospheric upper baroclinic zones.
Upper air sounding are used to examine a cold front of average intensity. Vertical cross sections of potential temperature and wind, and horizontal analyses were compared and adjusted for consistency. These analyses were then used to study the evolution of the front, found to consist of a complex system of fronts occurring at all levels of the troposphere. Low level fronts were strongest at the surface and rapidly weakened with height. Fronts in the midddle troposphere were much more intense. The warm air ahead of the fronts was nearly barotropic, while the cold air behind was baroclinic through deep layers. A deep mixed layer was observed to grow in this cold air.
