A new study published in Geophysical Research Letters looks at the relationship between how fast a tropical cyclone intensifies and the amount of ice in the clouds that make up the storm. Hurricane scientists found that tropical cyclones with greater amounts of cloud ice are likely to intensify faster than those with less cloud ice.
New Study Looks at How Different Techniques to Model the Hurricane Boundary Layer Can Improve Forecasts
In a new study published in Atmosphere, hurricane scientists looked at how turbulent mixing in the boundary layer affects the intensity and structure of hurricanes in NOAA’s Hurricane Weather Research and Forecasting (HWRF) model. They found that turbulent mixing affects where thunderstorms in hurricanes occur, and how fast air flows towards the center of a storm.
NOAA concludes Environmental Modeling Center (EMC) tasked reconnaissance for Major Hurricane Delta on October 9. The P-3 aircraft took off from Lakeland, FL at 5:00 AM EDT to survey the system’s circulation.
A new study published in Meteorological Applications finds that changes in the flight track patterns of aircraft flying into storms to collect observations for weather forecast models could positively impact forecasts. Differences in where data is collected within a storm changes the model forecast.
NOAA and Air Force Reserve Hurricane Hunters continue around the clock monitoring of Hurricane Delta as it traverses the Gulf of Mexico. Overnight flights on October 7 through midday October 8 found that Delta’s circulation is intensifying and expanding in size.
NOAA aircraft reconnaissance continued for Major Hurricane Delta on October 6, capturing the system’s quick maturation overnight. P-3 and G-IV missions are scheduled every 12 and 24 hours from Lakeland, FL. The National Hurricane Center (NHC) tasked NOAA’s Hurricane Hunters to identify the location and strength of the circulation center, and to survey the atmospheric conditions nearby and ahead of Delta. Instrumentation onboard the aircraft have sampled the system’s development, revealing a 55 knot rapid intensification in just 24 hours.
Aircraft reconnaissance operations began October 5 to investigate the location and strength of Tropical Storm Delta’s circulation. Tasked by the National Hurricane Center (NHC), NOAA’s P-3 aircraft took off at 1 PM EDT from Lakeland, FL.
After a week of daily map discussions led by student forecasters at the University at Albany-SUNY, as part of AOML’s Hurricane Field Program, NOAA interest in Tropical Storm Gamma has resulted in planned reconnaissance missions starting at 5 AM EDT on Saturday, October 3.
NOAA’s Hurricane Hunters continue reconnaissance for Major Hurricane Teddy, conducting numerous science experiments developed by AOML and its collaborators.
A new study published in Remote Sensing uses radar data from NOAA’s P-3 Hurricane Hunter aircraft to determine the characteristics a satellite would need to measure the surface wind in a tropical cyclone between areas of heavy rainfall. This study finds that satellites with higher resolution can measure larger regions of heavy rainfall.
