tJet Making Hurricane Predictions Faster

Beginning the week of August 18, ESRL's newest supercomputer "tJet" will enter acceptance testing and go into operation by August 21st. tJet will be vital to NOAA's Hurricane Forecast Improvement Project that aims to more accurately forecast tropical storms, hurricane intensity and tracking, as well as the dangerous storm surges related to hurricanes.

NOAA is dependent on highly reliable and resilient high-performance computing facilities to process large model runs and data assimilation experiments for the improvement of weather forecasts. tJet, one of NOAA's largest supercomputers, is a major upgrade to the existing capabilities hosted by ESRL. Based on the processor technology of its predecessor nJet, tJet's features have been compacted to offer a much higher compute capacity with approximately 10,032 cores vice the previous 3,520 cores. This means that high-resolution models such as the Hurricane Weather Research and Forecasting System can be run at a higher resolution than currently. Additionally, the more powerful system can now deliver real-time research forecasts to the hurricane forecasters of the National Weather Service faster and with better accuracy.

tJet is supported by NOAA's funding for hurricane research that quadrupled in 2009 to increase hurricane observations; advance forecast models through research, development, and engineering; increase computing power; and enhance collaboration with hurricane scientists in the private sector, government, and universities to advance research and operations.
