Multiscale resolution of shortwave‐longwave interaction

Multiscale Resolution of Shortwave-Longwave Interaction

In the study of time-dependent waves, it is computationally expensive to solve a problem in which high frequencies (shortwaves, with wavenumber k = kmax) and low frequencies (longwaves, near k = kmin) mix. Consider a problem in which low frequencies scatter off a sharp impurity. The impurity generates high frequencies which propagate and spread throughout the computational domain, while the dom...

Multiscale Statistical Properties of a High-Resolution Precipitation Forecast

Small-scale (less than ;15 km) precipitation variability significantly affects the hydrologic response of a basin and the accurate estimation of water and energy fluxes through coupled land–atmosphere modeling schemes. It also affects the radiative transfer through precipitating clouds and thus rainfall estimation from microwave sensors. Because both land–atmosphere and cloud–radiation interact...

Multiscale resolution in the computation of crystalline microstructure

CRYSTALLINE MICROSTRUCTURE SÖREN BARTELS AND ANDREAS PROHL ABSTRACT. This paper addresses the numerical approximation of microstructures in crystalline phase transitions without surface energy. It is shown that branching of different variants near interfaces of twinned martensite and simple austenite phases leads to reduced energies in finite element approximations. Such behavior of minimizing ...
