AICS Cafe

AICS Cafe is a place where the researchers in AICS can frankly discuss about their researches beyond their own disciplinary wall in order to collaborate with each other. We plan to have it twice a month regularly. We welcome all people including the promotion office and administration division of K computer in AICS.

  • Purpose : In order to promote the research collaboration beyond each of existing research disciplines, this seminar provides the discussion field for exchanging information, understanding neighboring researchers, and collaboration between each other.
  • Place: Workshop room (6th floor) at AICS
  • Lang : presentation in Japanese or English, the slide in English
  • Etc.: Please give your presentations clearly to researchers in other fields. Please do not hesitate to ask a question to the speakers.

The 71st AICS Cafe
Date and Time: Fri. May. 15, 2015, 15:00-16:00
Place: Workshop room (6th floor) at AICS
 

Title: Applying the Local Transform Ensemble Kalman Filter to the non-hydrostatic atmospheric model NICAM
Speaker: Koji Terasaki (Data Assimilation Research Team)

Abstract: Detail

The weather system is chaotic and known to be sensitive to the initial conditions. Therefore, it is important to estimate accurately the current state of the atmosphere for more accurate initial conditions. Data assimilation is a statistical approach to estimate the best possible atmospheric state using both simulation and observation data. The local ensemble transform Kalman filter (LETKF) is an advanced data assimilation method that is particularly efficient with parallel architecture computers.
Non-hydrostatic icosahedral atmospheric model (NICAM) is a weather forecasting model and has been developed by Computational Climate Science Research Team in AICS. Data Assimilation Research Team works collaboratively and applied the LETKF to the NICAM for assimilating various kinds of observations. We are developing a new system for assimilating satellite data. In this talk I will give a brief and clear introduction to data assimilation and present the most recent research on the newly-developed NICAM-LETKF system.
