"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!!
