"Big Data Assimilation: A New Science for Weather Prediction and 
Beyond”

Dr. Takemasa Miyoshi
RIKEN Center for Computational Science

Data Assimilation was introduced in numerical weather prediction to 
combine computer model forecasts with real-world observations, using 
dynamical systems theory and statistical mathematics. Computing, remote 
sensing, and information/communication technologies are all advancing 
rapidly, and Data Assimilation is becoming more popular as a means to 
perform cyber-physical fusion in other sciences and technology fields. 
At RIKEN, the Japan’s flagship research institute for all sciences, 
we pioneered future possibilities of numerical weather prediction by 
taking advantage of the powerful K computer, and Big Data from advanced 
sensing technologies such as the Phased Array Weather Radar and the 
Himawari-8 geostationary satellite. We thus developed innovative “Big 
Data Assimilation” (BDA) technology, and made possible a 
30-second-update of severe weather prediction at 100-m resolution, two 
orders of magnitude higher and faster than what is currently used in 
operational numerical weather prediction centers. I will talk about the 
exciting results of our BDA efforts in numerical weather prediction, 
and give a perspective towards Data Assimilation becoming a new science 
hub – from severe weather forecasting to many other new important 
applications.


¡¡Los esperamos!!
