Abstract: A technique of initialization for the primitive forecast equations is presented. The method consists of a marching prediction scheme performed in such a manner that the large-scale solution remains approximately steady, ...

Abstract: The structure of the thunderstorm gust front is investigated by a nonhydrostatic, two-dimensional (xz/) numerical model. In the model, which is dry, the production of negatively buoyant air by evaporation is parameterized ...

Abstract: In mid-1966 a new baroclinic numerical weather prediction model became operational at the National Meteorological Center, an event made possible by advances in computer and communications technology. The new model integrates ...
