Final report on PP CORSO-A to be delivered in April 2018 Guidelines forecasters on the use of products of small scale LAM NWP based on Sochi experience ~ 8 -10 pages 2018 CONTENTS DRAFT 1 INTRODUCTION The small scale (SS) NWP – why is feasible? 2 2. 1. 1 Access to LAM products Features of access to LAM NWP products Concepts for visualization of LAM NWP products for the local forecast centers with reduced technical opportunities 3 3. 1. 3. 2. 3. 3 3. 4 Recommended basic products, sequence and features of their analysis Forecasting maps Meteograms: features for mountain regions Main correction Postprocessing 4. 5. Challenges of verification of HR NWP results Forecaster Training aspects (based preparing of Sochi 2014)
Possible PT: • To generalize the experience gained for Sochi and winter conditions to other regions and seasons and to develop: Guidelines forecasters on the use of products of small scale LAM NWP

WG 4 participation in C 2 I PP: 5. 6 Forecasters’ feedback The main goal of the task Forecasters’ feedback is the evaluation of ICON-LAM forecasts by forecasting departments and the translation of this feedback to the COSMO -ICON community, in particular: • An assessment of the added value of ICON-LAM compared to COSMO in general. • Identification of decreased model skills for certain regions or certain weather regimes. • An assessment of the added value of ICON-LAM compared to COSMO in case of severe weather situations. • Additional requirements of ICON-LAM users with respect to data format and output meteorological variables. This goal is achieved by providing forecasting departments and, if available, other COSMO-ICON-LAM users with regular surveys. These surveys are collected and processed by a WG 4 representative from each of the participating institution at the end of phase 2 and phase 3. Using the outcome of these surveys, an assessment will be created that includes the subjective evaluation by forecasters and the objective verifications obtained by task 5. 5 (see subsection 5. 5). A comparison of the subjective and objective verification results is then made. Deliverables: A report containing the outcome of the surveys as well as a comparison with the objective results from task 5. 5 at the end of phase 2 and phase 3, i. e. by the end of 2019 and 2020. Resources: 0. 2 FTE per participant, i. e. 2 FTE in total. (depends on sharing the efforts with WG 5!)
New terms of reference, WG 4 work plan, new PPs/PTs • To be discussed during the WG 4 meeting joint with WG 5 in Offenbach with participation of Pierre Eckert • Ideas for PPs: - Blending of observations and model output in very short range forecasting. Such a project would require active WG 5 and WG 7 participation - Application of COSMO-ART - Shareable products for transportation (in particular, aviation), energy production (mainly, renewable energy), crisis management (severe weather) …
Thank you for your attention!
