HRD Debrief for missions into EP95/Pre-Ivo in collaboration with OTREC – 3 March 2020

HRD researchers and our collaborators from the NSF-sponsored Organization of Tropical Eastern Pacific Convection (OTREC) experiment discussed the results from the 4 P-3 and 3 NCAR G-V HIAPER missions into EP95 which eventually became Hurricane Ivo in the Eastern Pacific. IFEX flew 4 P-3 missions from Liberia, Costa Rica into the disturbance that became Ivo, … Continue reading HRD Debrief for missions into EP95/Pre-Ivo in collaboration with OTREC – 3 March 2020

HRD Debrief for missions into Hurricane Dorian – 30 January 2020

HRD researchers discussed the results from the 15 P-3 and 10 G-IV missions into Hurricane Dorian, AL05 (26 August - 5 September 2019). The format of the debrief was different than in the past. A brief overview is provided of the storm and missions, followed by a series of 8 short presentations discussing planned and … Continue reading HRD Debrief for missions into Hurricane Dorian – 30 January 2020

Paper on differences in rainfall between tropical disturbances that form into tropical cyclones and those that don’t published in Monthly Weather Review

Summary: Many weather satellites are outfitted with instruments that can see through clouds to sense where and how hard it is raining (the rain rate), and how much of the rain is occurring in deep convective clouds (cumulus and cumulonimbus clouds that form when warm air rises). They can also see tropical disturbances, which are usually … Continue reading Paper on differences in rainfall between tropical disturbances that form into tropical cyclones and those that don’t published in Monthly Weather Review

2019 Hurricane Field Program Season in Review and Hotwash, 13 November 2019

The purpose of the season review and "hotwash" is to review the highlights from the season and discuss what went right / what went wrong / and what could be done better in the future with respect to Hurricane Field Program operations/plans/logistics, as well as provide feedback to AOC about the aircraft and their operations. … Continue reading 2019 Hurricane Field Program Season in Review and Hotwash, 13 November 2019

Hurricane Field Program Update — Friday, September 20, 2019, 5pm EDT

NOAA49 will conduct a tropical cyclone in shear research in and around Hurricane Jerry.  Takeoff will be from Barbados at 1330 AST (1730 UTC), with recovery in Lakeland about 8 hours later.  NOAA42 will be conducting an operational INVEST mission into AL99 just to the east of the Windward Islands, with takeoff at 1030 AST … Continue reading Hurricane Field Program Update — Friday, September 20, 2019, 5pm EDT

Hurricane Field Program Update — Saturday, September 14, 2019, 11pm EDT

NOAA42 will conduct a third EMC-tasked mission into Tropical Storm Humberto on 15 September, departing Lakeland around 5 pm EDT (2100 UTC) and returning there 4.5 hours later.  The aircraft will sample Humberto in a butterfly pattern, and possibly gather data during an overpass of the Atmospheric Dynamics Mission Aeolus satellite to help validate its … Continue reading Hurricane Field Program Update — Saturday, September 14, 2019, 11pm EDT

AOML/HRD Seminar – Evan Forde – 29 August 2019

Evan presented a seminar titled "Relationship between Tropical Cyclone Genesis in the Main Development Region and Seasonal Tropical Cyclone Activity in the Atlantic Basin".  ABSTRACT Tropical Cyclone (TC) genesis in the Atlantic basin main development region (MDR) was evaluated from 1972-2015 to determine its relationship with seasonal TC activity.  Among other findings, a strong correlation … Continue reading AOML/HRD Seminar – Evan Forde – 29 August 2019

Hurricane Field Program Update — Tuesday, August 20, 2019

HRD successfully completed their last research NOAA P-3 mission into Invest 95E, located in the East Pacific, today collecting valuable data that will help towards better understanding how tropical storms develop. The data from the flight reveals the complicated circulation structure in developing storms and their link to precipitation (rainfall) processes, which are critical to … Continue reading Hurricane Field Program Update — Tuesday, August 20, 2019

Hurricane Field Program Update — Monday, August 19, 2019

HRD and the National Center for Atmospheric Research (NCAR) / National Science Foundation (NSF) Organization of Organization of Tropical East Pacific Convection (OTREC) East Pacific Convection (OTREC) Experiment team (see for details: https://www.eol.ucar.edu/field_projects/otrec) flew a joint research mission yesterday (Sunday) with the NCAR/NSF G-V high-altitude airplane flying a lawnmower pattern around the disturbance environment associated … Continue reading Hurricane Field Program Update — Monday, August 19, 2019

Hurricane Field Program Update — Monday, August 19, 2019

HRD and the NOAA Hurricane Hunters successfully flew the first hurricane formation (aka, genesis) research mission out of Costa Rica yesterday into the disturbance identified as Invest 95E by the National Hurricane Center (NHC). The NOAA P-3 (NOAA42, “Kermit”) flew a complete “lawnmower” pattern encompassing the broad circulation observed in the Invest. HRD has tasked […]
