Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications

Summary: The Global Hawk, a drone or unmanned aircraft system, has been used since 2010 to gather data to improve weather forecasts. The Global Hawk can release dropsondes that measure temperature, pressure, humidity, and wind up to four times every second, starting at an altitude of up to 60,000 feet until it falls to the … Continue reading Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications

NOAA Hurricane Hunters to Fly Multiple Missions into Tropical Storm Sally and Hurricane Paulette

A very active peak in this year's Atlantic hurricane season has prompted NOAA's National Hurricane Center (NHC), Environmental Modeling Center (EMC), and AOML's Hurricane Research Division to task NOAA's G-IV and both P-3 aircraft to investigate multiple storms in the Gulf of Mexico and mid-Atlantic. GOES-East Geocolor of the tropical activity across the Atlantic basin AOML … Continue reading NOAA Hurricane Hunters to Fly Multiple Missions into Tropical Storm Sally and Hurricane Paulette

AOML Scientists Provide An Outlook for Potential Hurricane Research Flights

Today Hurricane scientists turned their attention to the area of storms in the tropical Atlantic, named Invest 95L.  They have tentatively planned to send the high-altitude jet Gulfstream-IV (G-IV) to St. Croix on Sunday, September 13 to begin sampling Invest 95L on Monday, September 14. Their provisional plan includes collecting measurements that address questions posed … Continue reading AOML Scientists Provide An Outlook for Potential Hurricane Research Flights

AOML Scientists Evaluate the Potential for Research in Tropical Storm Paulette

Each day hurricane scientists meet to discuss the viability of systems and the logistics needed to complete possible research goals.  In today's meeting, on Wednesday September 9, the scientists decided to wait one more day before making a decision to deploy to St. Croix or hold off for future opportunities.  Tropical Atlantic view from GOES-East showing … Continue reading AOML Scientists Evaluate the Potential for Research in Tropical Storm Paulette

AOML reviews science conducted during Hurricane Hunter missions into Laura

Hurricane scientists at AOML provided guidance and data support for National Hurricane Center (NHC) and Environmental Modeling Center (EMC) tasked reconnaissance into Hurricane Laura, identifying critical information about the system’s location, development, and intensification. Beginning on August 20th, 11 P-3 and 6 G-IV missions were conducted, capturing the complex lifecycle of Laura until its eventual … Continue reading AOML reviews science conducted during Hurricane Hunter missions into Laura

AOML Scientists Support Mission into Tropical Storm Nana from Air and Ground

NOAA’s P-3 Hurricane Hunter aircraft completed a flight into Tropical Storm Nana in the Caribbean on the morning of September 2.  AOML scientists onboard the aircraft, and from the ground, quality controlled and sent dropsonde and radar data to the Environmental Modeling Center (EMC) and National Hurricane Center (NHC) in real time.  According to NHC, … Continue reading AOML Scientists Support Mission into Tropical Storm Nana from Air and Ground

Paper on a new version of HWRF that follows more than one storm at a time published in Atmosphere

Satellite picture of four tropical cyclones in the Atlantic and East Pacific basins. The blue boxes represent high-resolution grids surrounding eachtropical cyclone in the new version of HWRF. Summary:  NOAA’s operational Hurricane Weather Research and Forecasting Model (HWRF) has become an important tool for both hurricane forecasters and researchers. HWRF has three domains around only … Continue reading Paper on a new version of HWRF that follows more than one storm at a time published in Atmosphere
