Towards Rapid Update Cycling for short range NWP forecasts
in the HIRLAM community


Magnus Lindskog, Siebren de Haan, Sigurdur Thorsteinsson, Shiyu Zhuang, et al.

In the HIRLAM NWP community focus is at present on application of forecast models at a horizontal resolution of 1-5 km. Data assimilation is being adjusted to handle observations with high resolution in space and time and to meet the challenges associated with km-scale data assimilation. Initial HIRLAM experiences from rapid update cycling will be presented and future plans outlined.
