  1. RT3, Feb 2009 Markku Rummukainen, Jens Hesselbjerg Christensen, Geert Lenderink & all of RT3

  2. The aim of the working meeting is to • Finalise the work on RCM weights • f1-f6, combining the weights • special journal issue on RCM weights • Report of Western Africa RCM simulations and plan continued efforts • RCM evaluation • AMMA region evaluation data and joint analyses Signatur

  3. Issues • Status of the runs, share results • Archiving (daily on native grids, monthly means on reg CRU 0.5deg grid) • Run through to 2007 • Joint RCM evaluation • AMMA region evaluation data: task force: Miguel, Neil, Cyril – mid-March. Focus on gridded data. • Analyses: Annual course of the monsoon system viz precip (DMI), Monthly means, biases etc (T, MSLP, etc; Univ Liverpool), model intercomparisons?? (soil moisture-precip feedback; KNMI), cf CEOP-RCM intercomparison, Niger catchment (GKSS), (CHMI-CUNI), lqt-vert cross sections, jets (UCLM), climate sensitivity, trends?? (MPIMET), soil moisture feedback, role of SST, cf; WAMME-special issue “benchmarks” Richard asks Dave for the papers and a “condensate”?? (HC), Canary Islands, scenarios, synoptic climatology (AEMET), ?? (SMHI) … AMMA-MIP cross-sections, other diagnostics? (Françoise, Miguel to suggest), IWV, wind, MSLP->Fleur, case study with 1-D RCM versions<- Cathrine –ACTION ON ALL: concretise by end of Feb! • Consider all RCMs? • Papers etc. • Overvier article in the special RT3 issue, on WP3.5 • Papers at the Lund RCM workshop 4-8 May? (Deadline 15 Feb, poss +1 week -> 22 Feb) Signatur

  5. Focus on RCM runs and analyses for Western Africa (WP3.5) • 13.20-14.20 Discussion • Presentations by AMMA, focusing on key climate processes and model evaluation • 14.20-14.40 Evaluation of climate models over West-Africa: AMMA-MIP (Françoise Guichard) • 14.40-15.00 Dynamics of the African heat low on climate scale (Romain Roehrig) • Coffee • 15.30-15.50 A methodology to evaluate parameterization schemes on West Africa (Jean-François Gueremy) • 15.50-16.10 Pulsation of the humidity field before the monsoon on-set, synoptic scale (Fleur Couvreux) • 16.10-16.30 Example of process-oriented validation: case of a diurnal cycle of the convection in semi-arid conditions (Catherine Rio) • 16.30-18.00 Discussion on RCM analysis plans, incl availability and need of e valuation data; Expected scientific outcome; Special journal issue? Signatur

  6. Signatur

  7. WP3.5 issues • RCM run status? • Archiving status/expected? • Minimum output to be archived? • Availability of evaluation data (esp. from AMMA) • Common and/or specific analyses? • Special journal issue (or co-ordinated articles), by ENSEMBLES or ENSEMBLES+AMMA • Papers at the Lund RCM workshop 4-8 May Signatur

  8. Analysis plans and archived data needs… • ICTP: basic climate features (need daily mean T &P, montly pressure-level winds) • GKSS: precipitation • SMHI: T, P, Sfc SW & LW radiation, H, LE • KNMI: P and sfc fluxes • AMMA: Integrated water vapour, MSLP, wind at pressure levels Signatur
