Severe Tropical Cyclone Gwenda near peak intensity (NOAA) On April 6, 1999, Severe Tropical Cyclone Gwenda reached record intensity (up to that time) for an Australian tropical cyclone. As it idled off Australia’s northwest coast the one-minute sustained winds were estimated to peak at 150 mph (240 km/hr). The estimated central pressure of […]
At the 31st Conference on Hurricanes and Tropical Meteorology a paper coauthored by Pennsylvania State University researchers Fuqing Zhang and Yonghui Weng together with HRD researchers John F. Gamache and Frank D. Marks titled “Performance of convection‐permitting hurricane initialization and prediction during 2008–2010 with ensemble data assimilation of inner‐core airborne Doppler radar observations” received the […]
Jennifer Calderon-Diaz, HRD’s Administrative Assistant, has been named NOAA’s Team Member of the Month. As part of her job, Jennifer supports HRD’s annual Field Program by coordinating HRD research scientists for flight missions around and into the storms. The uncertainty of when and where storms will develop often requires her to accomplish this at a moment’s notice. During the 2013 furlough […]
In April of 2004, NOAAm in conjunction with the National Science Teachers’ Associationm issued an informational poster on severe weather for use in schools across the United States. It was sent to over 50,000 elementary, middle, and high school classrooms. Another 20,000 copies were distributed to individual teachers and students over the next five years. […]
Bill Gray in 2006 In April of 1984, Bill Gray and a team of meteorologists from Colorado State University issued their first seasonal hurricane forecast. This was the first attempt to prognosticate the number of tropical storms and hurricanes in the Atlantic basin for the coming year using statistical correlations with various parameters, such […]

Catarina near its peak intensity. (NASA – MODIS) On March 28, 2004, a rare South Atlantic tropical cyclone smashed into the Brazilian coast. Tropical cyclone development in this region is scarce due to the lack of favorable conditions, such as low shear or easterly waves coming off of Africa. In this case, […]
Cyclone Vance near its peak (NOAA) On March 22, 1999 Severe Cyclone Vance made landfall on Australia’s west coast, near Exmouth. The storm was Category Four on the Australian Bureau of Meteorology tropical cyclone intensity scale scale with wind gusts measured at 166 mph (267 km/hr) at Learmonth. This surpassed the previous highest recorded gust in Australia […]
