Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review

Summary: During each hurricane season, NOAA’s Gulfstream-IV (G-IV) Hurricane Hunter aircraft measures wind, temperature, humidity, and pressure in and around hurricanes threatening the United States.  An instrument called the dropwindsonde is released from the G-IV to collect the data as it falls to the ocean surface.  The plane currently flies where we expect observations from the … Continue reading Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review

Paper on a new way to input observations into weather models published in Monthly Weather Review

Summary:  Predicting the weather with 100% accuracy is an impossible task. Doing so would require full knowledge of the Earth system (the air, water, land, etc.) including the present state of the atmosphere (its wind, temperature, humidity, etc.). It would also require a complete understanding of everything that causes the weather. In reality, our understanding … Continue reading Paper on a new way to input observations into weather models published in Monthly Weather Review

Paper on possible improvements to forecasts from additional radio-occultation satellite data published in Monthly Weather Review

Summary: The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) are a set of satellites that were launched in 2006 and orbit the earth about 500 miles above ground. They use radio signals from Global Positioning System (GPS) satellites in a process called “radio occultation” to measure temperature and moisture with high accuracy every 100 … Continue reading Paper on possible improvements to forecasts from additional radio-occultation satellite data published in Monthly Weather Review

Paper on the impact of using Hurricane Hunter data in the HWRF model published in Monthly Weather Review

We studied how Hurricane Hunter aircraft observations can improve tropical cyclones forecasts from the National Oceanic and Atmospheric Administration's Hurricane Weather Research and Forecast (HWRF) model. Important Conclusions: Hurricane Hunter aircraft data generally improve HWRF forecasts. These improved forecasts are mainly in weak storms, since, without the data, HWRF often forecast storms that are too … Continue reading Paper on the impact of using Hurricane Hunter data in the HWRF model published in Monthly Weather Review

HRD Seminar – Dr. Karina Apodaca, CSU/CIRA and AOML/HRD – 24 October 2018

Dr. Apodaca presented a seminar titled “Advances in new data assimilation methodologies and observations for the benefit of NOAA operations". ABSTRACT: In an effort to advance the operational weather forecasting enterprise a vital objective is having the ability to accurately predict severe weather. Integrating new methodologies to enhance data assimilation systems and incorporating new and … Continue reading HRD Seminar – Dr. Karina Apodaca, CSU/CIRA and AOML/HRD – 24 October 2018
