Modelling Glaciers in the HARMONIE-AROME NWP model

HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multipurpose SURFEX surface model. It is developed for high resolution (1–3 km) weather forecasting and applied in a number of regions in Europe and the Mediterranean. A version of HARMONIE-AROME is also under development for regional climate modelling. Here we run HARMONIE-AROME for a domain over Greenland that i...

Coupling of air quality and weather forecasting - progress and plans at met.no

The first system, the “Severe Nuclear Accident Program” (SNAP) model was developed at met.no to allow emergency risk assessment (Saltbones et al., 1995, 1998). This is a Lagrangian particle model transporting gases, noble gases, particles of different size and density. The modeled processes are advection and diffusion by random walk, dry deposition with gravitational settling velocity parameter...

Numerical weather prediction and HIRLAM project

National meteorological services are required to provide short and medium range weather forecasts, warnings and alerts for their territory. Modern-day weather forecasting is highly relying on numerical weather prediction (NWP). The medium range forecasts are produced with global models using the whole of Earth as a domain having a horizontal resolution of about 20-40 km. For short range applica...

A Parallel Implementation of the Hirlam Model

This paper is a status-report describing the e ort to implement the HIRLAM numerical weather prediction model on a MasPar MP{1 system. Several results of the parallel implementation of the forecast model are presented. Di erences with more traditional implementations on vector-computers are outlined. While work is still going on, this report mainly focuses on explicit Eulerian methods. Semi-imp...
