The new textbook titled “Advanced Numerical Modeling and Data Assimilation Techniques for Tropical Cyclone Predictions”, was co-edited by HRD scientist Dr. Sundararaman Gopalakrishnan. It is based on a series of lectures by scientists from the US, India and Australia, at a workshop held in Bhubaneswar, India on 9-14 July 2012. It provides information on recent advances in tropical cyclone observations, data assimilation (the process of getting these observations into forecast models), and these forecast models, and is meant to be used for teaching and reference at universities and research laboratories. There is specific information about how tropical cyclones move, how their structure and strength changes, and forecasts of impacts like storm surge and rainfall.
The new textbook has 27 chapters, three of them authored by HRD scientists. The first chapter, by HRD Director Frank Marks, provides an overview of NOAA’s Hurricane Field Program, the use of aircraft observations for improving forecasts, and future observing technologies. Drs. Thiago Quirino and Sundararaman Gopalakrishnan discuss how to derive some useful and basic information from forecast models. And a chapter on the Hurricane Boundary Layer by Dr. Gopalakrishnan and others shows the importance of near-surface processes that control structure and intensity change in tropical cyclones.
The textbook was first released in India during TROPMET 2016 Climate Change and Coastal Vulnerability organized by the Indian Meteorological Society (IMS), and is available here.
