Paper on the types and sizes of ice particles in hurricanes published in the Journal of Applied Meteorology and Climatology

Many people have experienced the heavy rain and warm, moist air when hurricanes reach land. But several miles above the ground, where the air is very cold, hurricane clouds are made up of snowflakes and tiny ice particles called ice crystals. The computers that scientists use to forecast where hurricanes will go and how strong …

HRD Seminar – Dr. Andy Hazelton, Princeton University and NOAA/GFDL – 25 October 2016

Dr. Hazelton presented a seminar on “Evaluation of Tropical Cyclone Structure in High-Resolution FV3 Simulations". Abstract The FV3 dynamical core with GFS physics has shown skill both in global forecasting and the ability to simulate high-impact weather events.   Here, a regionally stretched and nested version of the model, centered over the Atlantic Basin with a grid …

HRD seminar – Michael Kozar, Risk Management Solutions – 8 December 2015

Michael presented a seminar “Evaluation of Hurricane Wind Field Forecasts from Global Models Within the TIGGE Archive“. Abstract: Short- and mid-range forecasts of select North Atlantic hurricanes over the past few seasons—including Sandy (AL182012), Gonzalo (AL082014), Irene (AL092011), and Isaac (AL092012)—are analyzed to quantify biases and error magnitudes found across a storm’s entire wind field. …

HRD seminar – Bryce Tyner, North Carolina State University – 15 July 2014

Bryce presented a seminar on “ Sensitivity to the Planetary Boundary Layer Scheme for High-Resolution Simulations of Irene (2011) ”. Abstract Turbulent transport associated with large eddy circulations (LECs) in the hurricane boundary layer (HBL) are not well understood. With the rapid growth in computational capabilities, it is now possible to resolve these LECs and …
