  4. Restructuring of the Panel The Panel has been (and is being) restructured trying to make it more efficient at Regional level. New members have been asked to join the Panel to engage people personally involved in LAM EPS and then in the position to make plans and to take commitments. The Panel has been divided in regional sub-groups: N. America Josh Hacker is the Focal Point Asia Jing Chen is the focal Point Europe Tiziana Paccagnella is the focal point S. America and Southern Hemisphere and Africa will be formalized later on. WWRP JSC meeting-Geneva 20 24 Febrary 2011

  6. TIGGE LAM Plan Following the last JSC meeting, the TIGGE LAM plan has been drafted and it is now under finalization. The present version of the plan is available at: http://www.smr.arpa.emr.it/tiggelam/ WWRP JSC meeting-Geneva 20 24 Febrary 2011

  7. TIGGE Plan: Scientific Issues • Mesoscale predictability • Mesoscale model inadequacy • Interactions between larger scale perturbations given by the driving global systems and “local” perturbations generated specifically for the LAM EPS. • Domain size and “local” perturbations on initial conditions • Perturbations associated to soil/surface description • Cycling short-range uncertainty for initial perturbations • Multi Model EPS • Quantify the additional benefit of Multi-LAM EPS • Evaluate the performance of convective permitting EPS systems and their benefit over restricted integration domains versus the combination of lower resolution ensemble systems • Predictability at the convection-resolving scale to support the design of the future LAM EPS systems. • Biases in deterministic models and calibration • Verification methods • Assess the probability of rare meteorological events • Probabilistic forecasts for other modelling applications • LAM EPS and Data Assimilation: which are the key characteristics of a LAM EPS to best represent short-range forecast error co variances for use in DA? Still to be refined and better focussed Indication how to develop research to be included More contributions shouldcome thanks to the new regional structure of the Panel.

  11. Archiving Archiving of high priority parameters on regular lat/lon grids. • CMA is starting the archiving of TIGGE LAM HP parameters from CMA Regional system. • The archiving of European products at ECMWF has been slowed down due to other priorities at ECMWF. Archiving of TIGGE LAM products on their native grids • LAM EPS are going to run at the convective-permitting scale. Products on the native grids should be made available and tools to manage these data should be developed. As regards Europe, this task has been included into the GEO-WOW FP7 WWRP JSC meeting-Geneva 20 24 Febrary 2011

  12. HIPRECA: HIgh resolution PREcipitation Analyses for verification as a complement to TIGGE and TIGGE LAM products. The possibility to implement an European archive of high resolution precipitation analyses based on high density network data is being explored. Contacts are established with ECMWF and with other European groups and initiatives with the same objectives. WWRP JSC meeting-Geneva 20 24 Febrary 2011

  13. HIPRECA: HIgh resolution PREcipitation Analyses for verification as a complement to TIGGE and TIGGE LAM products. Present status Unofficial agreement with David Richardson and Anna Ghelli to start the implementation of the dataset at ECMWF. Anna Ghelli is already collecting data from the European local networks.

Present status Unofficial agreement with David Richardson and Anna Ghelli to start the implementation of the dataset at ECMWF. Anna Ghelli is already collecting data from the European local networks. Cooperation with other similar initiatives in Europe. A meeting has been organized by Anna Ghelli at ECMWF on the 2nd Dec 2010. This meeting was aimed to coordinate this activity with the EUMETGRID/EUMETNET project leaded by Ole Tveito from Met.No. Participants: Anna Ghelli (ECMWF), Ole Tveito (Met.No), Dan Hollis (MetOffice), Tiziana Paccagnella (ARPA-SIMC TIGGE LAM). A cooperation has been set up toward the definition of a coordinated activity (to be hopefully funded by submitting a project proposal to EU) This initiative should also link with other ongoing projects like EURO4M and ARCIS (Northern Italy initiative) WWRP JSC meeting-Geneva 20 24 Febrary 2011

Present status Unofficial agreement with David Richardson and Anna Ghelli to start the implementation of the dataset at ECMWF. Anna Ghelli is already collecting data from the European local networks. Required preliminary actions: Define the official agreement with ECMWF (waiting for an answer from D. Richardson) Write a letter to the data providers to ask their formal agreement . Fill gaps in the data already collected at ECMWF Cooperation with other similar initiatives in Europe. A meeting has been organized by Anna Ghelli at ECMWF on the 2nd Dec 2010. This meeting was aimed to coordinate this activity with the EUMETGRID/EUMETNET project leaded by Ole Tveito from Met.No. Participants: Anna Ghelli (ECMWF), Ole Tveito (Met.No), Dan Hollis (MetOffice), Tiziana Paccagnella (ARPA-SIMC TIGGE LAM).

  17. Contribution to the definition of the GEO-WOW FP7 proposal Tiziana Paccagnella proposed two tasks to be included to this project proposal: 1st task: TIGGE LAM archive Extension of the TIGGE archive to include products from the several Limited Area Ensembles running operationally at the different centres in Europe. Products transmitted and archived on their native grid. 2nd task High Resolution precipitation analyses Implementation of a dataset based on data from european high density observational networks Due to the limited available funds, only the first task has been included. The second task should be carried on as a contribution of ECMWF to the TIGGE archive (see previous paragraph 4). WWRP JSC meeting-Geneva 20 24 Febrary 2011

  25. Some Concluding Remarks The Plan I hope we have the Plan finalized before July 2011. Actions will be regularly updated (?) WWRP JSC meeting-Geneva 20 24 Febrary 2011

  26. Some Concluding Remarks TIGGE LAM activities, even if planned , are generally very difficult to be concretized. The lack of devoted resources is one of the reasons but probably much more could be done, even without funds. One of the obstacle in stimulating coordinated actions among TIGGE LAM groups, is the difficulty to perceive the added value given by the cooperation mainly due to the sparseness and non homogeneity of LAM EPS initiatives. WWRP JSC meeting-Geneva 20 24 Febrary 2011

  27. Some Concluding Remarks TIGGE LAM was set up as a separate branch of TIGGE but now, to support its effective development, it is necessary to start its real integration in GIFS/ TIGGE whenever it is possible. This concept should be reflected in the GIFS plan with corresponding objectives and actions in the TIGGE LAM plan. WWRP JSC meeting-Geneva 20 24 Febrary 2011
