Priority Projects … • PP QPF finishes as planned by the end of 2007 (final report & paper). • PP UTCS: Dmitrii WG 3: Plans for next year 2

Work Packages … All but two WPs ongoing. – New / changed: • convection

Work Packages … All but two WPs ongoing. – New / changed: • convection • continuation of work started within PP QPF in the framework of a WP • • (purely) convective cases (~5, mainly underprediction) additional cross-experiments more sensitivity runs coordination: Federico Grazzini • implementation of the IFS version of the Tiedtke-Kain. Fritsch CPS (know-how transfer from Silke Dierer to Paola Mercogliano, Massimo Milelli, Davide Cesari). • UTCS task 4 ('slowdown of CPS', Tiedtke scheme) • all the above work may lead to the formulation of a new priority project until the next General Meeting WG 3: Plans for next year 3

Work Packages … • soil and vegetation • extend TERRA stand-alone: implement all available options (Ament) • 1 d sensitivity studies, comparison with data in Lindenberg, Ferrara, and more (Fluxnet, etc; Vogel) • implement most promising changes into the full 3 d model (Ament) • run 2 d TERRA stand-alone (COSMO-2 domain) to obtain ICs for full 3 d runs (Ament) • run 3 d test cases to see impact of changed soil moisture (Ament, Milelli, Mercogliano, …) • coordination of all the above: Gerd Vogel • Mosaic (Ament) • MSMA (Ament) WG 3: Plans for next year 4

Work Packages … • Implementation of sub-grid scale orography (SSO) scheme (Lott and Miller

Work Packages … • Implementation of sub-grid scale orography (SSO) scheme (Lott and Miller (1997), GME/IFS-code) • form drag / blocking & gravity wave drag • implementation and provision of external parameters by Jan-Peter Schulz • tuning of relevant parameters for the COSMO-EU by Jan. Peter, other partners could (or should!) be interested WG 3: Plans for next year 5
