Transcription

1 WMO/WWRP/THORPEX World Weather Open Science Conference Sunday 17 Thursday 21 August 2014, Montréal, Canada Scientific Program The overarching theme of the OSC is Seamless Prediction of the Earth System: from minutes to months. The science presented at the conference will range from basic research that extends our knowledge of processes and methods to the applied research required to put the prediction system together and assess the impacts of weather and climate events.

2 The scientific program will be organized around five science themes: Data Assimilation and Observations; Predictability and Dynamical/Physical/Chemical Processes; Interactions between sub systems; Prediction of the Earth system: putting it all together; Impacts of weather and climate events (joint session with UPC) A particular focus will be given also to major cross cutting themes, such as ensemble prediction.

3 COMPOSITION ATMOSPHERE SURFACE MARINE ECOSYSTEMS Interactions between sub systems; Prediction of the Earth system: putting it all together.

5 WMO/WWRP/THORPEX OSC: Scientific Program Themes Data Assimilation and Observations Remote sensing of weather (radar, satellite, GPS, lightning ) 4D data assimilation Ensemble techniques Remote sensing of atmospheric constituents Remote sensing of surface (soil moisture..) Oceanic observation In situ observations QPE, snow and sea ice analyses Interactions between sub systems Ocean cryosphere atmosphere Air land and water cycle Atmosphere chemistry Storm surge and wave modeling Ecosystems Impacts of weather and climate events Megacities: air quality and weather impacts Flood, landslide, forest fire, drought, storm surge, avalanche Volcanic ash Water quality Energy Transport Agriculture Predictability and Dynamical/Physical/Chemical Processes Numerical methods and next generation models Sub grid parameterization (grey zone, gravity waves, orography, land surface, turbulence ) Ensemble and stochastic forcing Boundary layer (atmospheric and oceanic at all latitudes) Clouds and convection (observations, processes and microphysics) Tropical systems (tropical cyclones, monsoons, MJO) Tropical extratropical interactions Predictability and dynamics of the ocean Prediction of the Earth system: putting it all together Urban prediction (weather, aerosol and AQ) Nowcasting Local and Regional high resolution prediction (weather, aerosol and AQ) Global medium range prediction (weather, aerosol and AQ) Sub seasonal to seasonal prediction Polar prediction Tropical prediction Verification at all time and space scales Hydrology and water cycle Ensemble prediction Meteorological applications Developing operational forecast techniques

6 The SPC accepted the distribution of tasks as described in the SPC composition annex. The SPC is content with the sub-themes. Action 1: Sub-theme short descriptions need to be provided. (Jones and Brunet) Done. The SPC appreciates the User Programme Committee, but would like to understand how to engage with. Action2: A first phone discussion is needed for starting the coordination between the Science Programme Committee and the User Programme Committee. (Mills, Roger, Dabbert, Chan, Jones and Brunet) The development of sessions should depend in part on the abstracts received, but it is the role of the SPC to develop in advance the focus for each of the oral sessions. It is not possible to cover all aspects of the WWRP science in one conference, so the oral session topics will need to focus on the most important science issues of the next ten years. The poster sessions will be able to provide enough flexibility for the other science topics that are not covered. Action 3: The SPC members should develop the session structure for each theme: Divide the science themes into sub-themes and identify 1-2 conveners for each of the sub-themes. The conveners would do the main work of putting the program together following abstract submission. We should prepare a session (or preferably evening event) on the future of WWRP. The past and present activities will be covered by the normal sessions. (SPC members as described in Annexes)

7 Action 4: It is planned also to have a white paper written on each sub-theme coordinated by the conveners. These white papers will synthesize several recent workshops, reports and published literature as appropriate to underline the scientific basis, current capabilities and outstanding challenges for each sub-theme. These white papers will be the basis of a WWRP OSC monograph that will be widely publicized and disseminated. (Conveners, Brunet and Jones) We need to compile a list of prospective keynote speakers (including plenary speakers). These should be high profile scientists who will both give good talks and attract participants. It would be ideal to include both established experts and rising stars. We envisage two keynote speakers for each theme plus speakers for cross-cutting themes (ensembles, major field campaigns, TIGGE.). This means in practice for Science we should have 15 invited speakers for the science programme. The SPC will propose a list of speakers for review by the International Organizing Committee (IOC). Action 5: The SPC members to suggest names and co-chairs to send a list to IOC for decision making (see Annexes). (All) Done We need to develop the structure/format of the conference and the optimal number of sub-themes. Action 6: A first draft should be produced before the end of August.
