Study on the impact of the new CYGNSS satellites on hurricane forecasts released online in Monthly Weather Review

Part of the difficulty of forecasting tropical cyclone (TC) track and intensity (where the TC is going and how strong it will be) stems from the lack of frequent, accurate observations over tropical oceans where TCs form and develop. While Hurricane Hunter aircraft can collect vital observations in and near TCs, those observations are limited … Continue reading Study on the impact of the new CYGNSS satellites on hurricane forecasts released online in Monthly Weather Review

NOAA Hurricane Hunters fly into and around Fred, Grace, and Henri, and gear up for the next system

NOAA Hurricane Hunters completed 6 missions into Tropical Storm Fred, and 11 and 7 missions in and around Hurricanes Grace and Henri, respectively. The first mission into Fred occurred before the system had a well-defined center and was not yet named a tropical depression. Subsequent missions sampled the dry air and wind shear around Fred … Continue reading NOAA Hurricane Hunters fly into and around Fred, Grace, and Henri, and gear up for the next system

Paper on accomplishments of NOAA’s Hurricane Field Program and future plans released online in The Bulletin of the American Meteorological Society

This review article highlights recent research from NOAA/AOML/Hurricane Research Division’s Hurricane Field Program – Intensity Forecasting Experiment (IFEX) geared to improving our understanding and forecasting of tropical cyclones (TCs). It details the accomplishments of IFEX during the 16 years of its existence, for example •  describing how IFEX addressed important issues like predicting rapid intensification … Continue reading Paper on accomplishments of NOAA’s Hurricane Field Program and future plans released online in The Bulletin of the American Meteorological Society

HRD recaps flights into Hurricane Elsa

NOAA conducted six flights into Hurricane Elsa earlier in July, four with the P3s and two with the G-IV. The G-IV operational synoptic flow missions were conducted to gather information from high-levels of the atmosphere around Elsa to improve model forecasts of the storm's track and intensity. The P3 missions were conducted to gather data … Continue reading HRD recaps flights into Hurricane Elsa
