JAMSTEC JCOPE Ocean Modeling  

JCOPE-T ocean current forecasting south of Shikoku, Japan
  Important: page is not updated more from November 15, 2016

This web page provides some results from JCOPE-T ocean modeling system, selected for purposes of supporting JAMSTEC "Chikyu" drilling ship operations during September - November 2016. Results are presented for the drilling point location around 32°22.0095'N, 134°57.9930'E marked by large black dot on the ocean current maps.
Data of two models: JCOPE-T-EAS for wider region of East-Asian Marginal Seas and JCOPE-T-JCW (ne73) for smaller region of Japan Coastal Waters are included. From September 9, 2016 these two models use different data assimilation schemes. Difference between two model results is a measure of ocean forecast uncertanties (error).
Forecasts are updated almost daily creating new bulletins with ~10 days forward predictions. Some bulletins could be skipped and some missing in case of computer system maintenance.
Special Best Estimates bulletin provides history of surface ocean nowcasts followed by recent forecasts. On the archived nowcast maps by purple line is plotted weekly-mean position of Kuroshio axis as reported by MIRC (Marine Information Research Center) observational data analysis if such data are available.
Keyboard keys could be used for navigation in time. To use it, move the focus (click mouse) on background and the "N" or "n" keys will step on one hour forward, when "P" or "p" - one hour backward.
You can download extracted from modeling results velocity data in CSV format for the fixed ADCP location from http://www.jamstec.go.jp/jcope/data/chikyu.2016.09/ web page.
