1 Water Vapour, Meteorology, and Climate
Solar-Terrestrial Centre of Excellence Water Vapour, Meteorology, and Climate Roeland Van Malderen, Eric Pottiaux, Hugues Brenot

2 STCE Annual Meeting Meridian room, 7 June 2013
Introduction Meteorology Antarctica Climate workshop held on 26 November, 2012 about 20 participants, from BISA, ROB, RMI, KUL, (and ULB ) 11 (12) oral presentations, 7 poster presentations rather than giving a report/summary, we will focus here on ongoing activities and opportunities in this field! STCE Annual Meeting Meridian room, June 2013

3 special focus on Antarctica!
Introduction Meteorology Antarctica Climate Meteorology Climate clouds/precipitation weather forecast nowcasting extreme events: floods, thunderstorms H2O = most important greenhouse gas water vapour feedback mechanism to be included in climate models! water vapour trends? what about stratospheric H2O? Water vapour special focus on Antarctica! STCE Annual Meeting Meridian room, June 2013

4 Clouds/precipitation STCE Annual Meeting Meridian room, 7 June 2013
Introduction Meteorology Antarctica Climate Clouds/precipitation Jabbeke RMI Wideumont RMI Zaventem Belgocontrol clouds  Meteosat images clouds  precipitation? precipitation  radars precipitation type (hydrometeor classification)  dual polarization radar (Jabbeke) STCE Annual Meeting Meridian room, June 2013 Jean Neméghaire (RMI) Laurent Delobbe (RMI)

5 Maarten Reyniers (RMI) STCE Annual Meeting Meridian room, 7 June 2013
Introduction Meteorology Antarctica Climate Nowcasting RMI’s nowcasting system: INCA CE collaboration several meteorological fields: precipitation (type), cloudiness, visibility, etc. input: radar, elevation data, weather stations, rain gauges, satellite data, NWP forecast for convective cells could be improved Maarten Reyniers (RMI) STCE Annual Meeting Meridian room, June 2013

6 Nowcasting: Global Navigation Satellite System (GNSS) stations

7 Nowcasting: Global Navigation Satellite System (GNSS) stations
Introduction Meteorology Antarctica Climate Nowcasting: Global Navigation Satellite System (GNSS) stations 2nd July 2012 at 13:00 UTC. Status: November 2012 (Several stations are located outside the represented domain). Nowcasting Domain ROB’s web portal to GNSS-meteorology and nowcasting STCE Annual Meeting Meridian room, June 2013 Eric Pottiaux (ROB, STCE)

8 NWP: Numerical Weather Prediction (NWP)
Introduction Meteorology Antarctica Climate NWP: Numerical Weather Prediction (NWP) 2nd July 2012 at 13:00 UTC. Status: November 2012 (Several stations are located outside the represented domain). Nowcasting Domain This hourly-updated solution is assimilated operationally by several national meteorological services through E-GVAP, but not directly by RMI (assimilation within ALARO)!

Introduction Meteorology Antarctica Climate Antarctica: reserach on aerosol-clouds-precipitation interaction at Princess Elisabeth Station HYDRANT, BELATMOS, GIANT projects KUL / RMI / BISA / UGent / ROB / Univ. Cologne / Univ. Luxembourg Cimel Sunphotometer  integrated water vapour automatic weather station 2 GPS stations at PES ceilometer, pyrometer, micro-rain radar  cloud base height, cloud type  cloud base temperature  snowfall rate, vertical profile STCE Annual Meeting Meridian room, June 2013 Alexander Mangold (RMI), Irina Gorodetskaya (KUL), Nicolas Bergeot (ROB, STCE)

11 H2O trends: 1st ) techniques inter-comparison 2nd) trends analysis

12 (Regional) Climate models
Introduction Meteorology Antarctica Climate (Regional) Climate models to develop very high resolution climate/air quality simulations for Belgium region,… improved understanding of the precipitation/temperature extremes, large scale circulation and its influence on Belgium region the role of the urbanization in future climate simulations ALARO-CLIM model at 4 km grid size resolution over Belgium with sophisticated cloud and precipitation parametrization and using a new land surface scheme called SURFEX. evaluation of the model with ERA-40 and Belgian climatological network of stations STCE Annual Meeting Meridian room, June 2013 Sajjad Saeed (KUL) Rafiq Hamdi (RMI)

13 Stratospheric water vapour
Introduction Meteorology Antarctica Climate Stratospheric water vapour Stratospheric Chemical Data Assimilation at BIRA-IASB: the Belgian Assimilation System for Chemical ObsErvations (BASCOE) 4D-Var system dedicated to stratospheric chemical observations Chemistry Transport Model (CTM) including 57 species (including H2O), 200 chemical reactions dynamics (u,v,T,p0) taken from ECMWF PSC parameterization to account for the effect of PSC on denitrification and dehydration and on the activation of chlorines BASCOE H20 on Jul. 15, 2008 from Aura MLS assimilation Quentin Errera (BISA) STCE Annual Meeting Meridian room, June 2013

14 Thank you for your attention!
Introduction Meteorology Antarctica Climate Opportunities compare observed trends in water vapour with climate model simulations compare for Belgium, the regional climate model output of the two groups coupling of ALARO & BASCOE for climate simulations (e.g. investigate stratosphere-troposphere exchange events like extra-tropical cyclones over the North Atlantic and Europe, Brain.be proposal) Thank you for your attention!
