Visitors: Cloud Overlap Enhancements Adopted for HWRF Operations

Visitors: Michael Iacono and John Henderson

Autumn 2021 | During their recent project for the DTC Visitor Program, Michael Iacono and John Henderson of Atmospheric and Environmental Research (AER) used the Hurricane Weather Research and Forecasting model (HWRF) to investigate an improved way to represent the sub-grid variability and vertical overlap of partial cloudiness within the calculation of atmospheric radiative transfer. Their exponential-random (ER) cloud overlap advancement was adopted by NOAA in the 2020 operational HWRF.  Read More

Director's Corner: DTC Outlook for the Future

Louisa Nance

Summer 2021 | Over the years, a major component of the DTC’s approach to facilitating the transition of research innovations into operations has been its support for distributed development of community software that includes the capabilities of the current operational systems.  This software support has provided the foundation for conducting testing and evaluation that can inform the research to operations (R2O) process.  The DTC’s software support responsibilities have involved, to varying degrees… Read More

Lead Story: Accelerating Progress of the Unified Forecast System through Community Infrastructure

Summer 2021 | The goals of the Unified Forecast System (UFS) are ambitious: construct a unified modeling system capable of replacing dozens of independently developed and maintained operational prediction systems, while simultaneously paving the way for researchers in NOAA labs and the broader NWP community to access and use that system, improve it, and contribute their own innovations.  Toward these goals, the UFS… Read More

Who's Who: Mrinal Biswas

Summer 2021 | Mrinal Biswas was born and raised in Durgapur, West Bengal, India, a small industrial town. He was raised by a Civil Engineer father while his mother took care of him and his sister. He enjoyed school but even more enjoyable was the time he played outdoors with his friends late into the evening. He was fascinated with anything electronic from radios to vinyl record players, even watches, disassembling them while his mom took his sister to school and quickly re-assembling them before… Read More
