Significance: “Cylindrical arrays can be impacted by the potential of strong surface and creeping wave effects as well as the difficulty of achieving low sidelobes. Even from a pattern-only perspective that neglects the system-level implications of transceiver electronics, backend architecture, calibration, and operational constraints, there are very few available large-array and pattern synthesis techniques for complex antenna element geometries within a cylindrical array framework. This makes it difficult to even simulate electromagnetically accurate cylindrical arraypatterns in an ideal system. Hence, our CPPAR demonstrator allows for many open challenges to be studied in a way that would not otherwise be possible.”

Significant Publication: Collaborative Efforts between the United States and United Kingdom to Advance Prediction of High-Impact Weather

The following significant paper publication was reported to headquarters the week of May 19. NOAA authors are bolded.

  1. Collaborative Efforts between the United States and United Kingdom to Advance Prediction of High-Impact Weather”

By John S. Kain (NSSL) , Steve Willington, Adam J. Clark (NSSL), Steven J. Weiss (NWS SPC), Mark Weeks, Israel L. Jirak (NWS SPC), Michael C. Coniglio (NSSL), Nigel M. Roberts, Christopher D. Karstens (OU CIMMS/NSSL), Jonathan M. Wilkinson, Kent H. Knopfmeier (OU CIMMS/NSSL), Humphrey W. Lean, Laura Ellam, Kirsty Hanley, Rachel North, Dan Suri.

Published in May 2017 American Meteorological Society’s Bulletin of American Meteorological Society, pages 937-948.

Significance: The Met Office brought expertise gained from its efforts using convection-allowing models (CAMs) to better represent the convective storms that bring flash flooding in the United Kingdom. The infusion of Met Office models and perspectives dovetailed exceptionally well with the rapidly growing National Severe Storms Laboratory and Storm Prediction Center proficiency in using CAMs to help predict tornadoes, large hail, and damaging winds. The successful collaborative efforts of the Hazardous Weather Testbed, NSSL, SPC, and Met Office are demonstrating that international collaboration can provide synergy, efficiency, and important scientific advances when it is strongly supported at both grassroots and institutional levels.
