New Publication from NOPP-Funded Research on Tropical Cyclone Forecasting

The NOPP Office would like to congratulate Shu-Chih Yang, Takemasa Miyoshi, and Eugenia Kalnay on their recent publication in Weather and Forecasting titled “Accelerating the EnKF Spinup for Typhoon Assimilation and Prediction.”

This publication is the result of a three year NOPP-funded project on Improving Tropical Cyclone Intensity Forecasting and is the third publication by this group in recent months!

In this study, a “running in place” (RIP) method was used in combination with the Weather Research and Forecasting model (WRF) within the local ensemble Kalman filter framework to accelerate the spin-up time of the cyclone and allow for more accurate analysis of cyclone tracks and intensities.  Click here for more information on the publication.

Additional publications from this research include “The Local Ensemble Transform Kalman Filter with the Weather Research and Forecasting Model: Experiments with Real Observations”, published in the Journal of Pure and Applied Physics, a description of which can be found here, and “Estimating the Impact of Real Observations in Regional Numerical Weather Prediction Using an Ensemble Kalman Filter” published in Monthly Weather Review.  More information on that article can be found here.

The citation is for this article is as follows:

Yang, S.-C., E. Kalnay, and T. Miyoshi, 2012: Improving EnKF spin-up for typhoon assimilation and prediction. Weather and Forecasting, 27, 878-897.

Congratulations again to Drs. Yang, Miyoshi, and Kalnay on their successful project and most recent publication!
