Heather Holbach discusses flights into Hurricane Ian at the National Tropical Weather Conference
The National Tropical Weather Conference is a professional conference for broadcast meteorologists and broadcast meteorology students focusing on tropical system forecasting, disaster preparedness, safety, research, impacts and social media communications. It was held last week at South Padre Island, TX. Heather Holbach presented a summary of NOAA Hurricane Hunter flights into Hurricane Ian last year. … Continue reading Heather Holbach discusses flights into Hurricane Ian at the National Tropical Weather Conference
Recap of 2022 Hurricane Field Program
Hurricane Field Program leadership held two sessions made up of a series of short science talks to wrap up the 2022 hurricane season. Talks included preliminary science results, challenges and successes in sampling and analysis strategies, modeling results, etc. The 2022 season saw 68 missions flown by NOAA aircraft into eight different tropical system. NOAA … Continue reading Recap of 2022 Hurricane Field Program
HRD participates in American Meteorological Society Annual Meeting
The world’s largest yearly gathering for the weather, water, and climate community took place earlier this month in Denver, Colorado. Scientists from NOAA’s Atlantic Oceanographic & Meteorological Laboratory participated in the 103rd annual American Meteorological Society meeting from January 8 - 12 through formal presentations, posters, panel discussions, and more. AOML/CIMAS scientist Mu-Chieh (Laura) Ko … Continue reading HRD participates in American Meteorological Society Annual Meeting
Study that shows improvements to hurricane models predict how the energy from the ocean transfers to the atmosphere underneath hurricanes published in Weather and Forecasting
This study examined how changes to the planetary boundary layer (PBL) scheme based on information from large-eddy simulations affected hurricane model forecast performance during the 2021 Atlantic hurricane season. The modified PBL scheme produced more realistic storm structures, on average, when compared to best-track information and observations from Hurricane Hunter Aircraft. The modified PBL physics … Continue reading Study that shows improvements to hurricane models predict how the energy from the ocean transfers to the atmosphere underneath hurricanes published in Weather and Forecasting
Recap of Julia and Lisa flights
NOAA conducted two flights into Julia and five into Lisa during October of this year, all in the Caribbean Sea. The main purpose of all the missions was to gather Doppler Radar and dropwindsonde data for ingestion into NOAA's computer models to improve forecasts. Flight tracks of missions into Julia (left) and Lisa (right) during … Continue reading Recap of Julia and Lisa flights
HRD scientists attend Hurricane Forecast Improvement Program Annual Meeting
Last week, researchers from HRD attended the 2022 Hurricane Forecast Improvement Program (HFIP) Annual Meeting in Miami, Florida. Group photo of some of the participants of the 2022 HFIP Annual Meeting, both in person and virtually. The primary objective of this meeting was to discuss key HFIP strategies including advances to NOAA's next-generation Hurricane Analysis and Forecast … Continue reading HRD scientists attend Hurricane Forecast Improvement Program Annual Meeting
Recap of Hurricane Ian flights
In September, NOAA conducted 15 missions in and around Hurricane Ian before its historic landfall in Florida. Among these were 8 P-3 missions and 7 synoptic surveillance missions conducted by the G-IV. One hundred forty-three dropwindsondes were released along with 18 Airborne Expendable Bathythermographs to measure profiles in the atmosphere and the ocean underneath Ian. … Continue reading Recap of Hurricane Ian flights
Study on how weak, disorganized tropical cyclones become upright allowing for intensification published in the Journal of Geophysical Research
This study shows how weak, disorganized tropical cyclones that have different center locations with height (misalignment) can develop a vertically aligned structure. The ability to predict whether and when a tropical cyclone will become aligned is important for intensity change forecasts, as storms can intensify quickly after achieving it. This study will help improve forecasts … Continue reading Study on how weak, disorganized tropical cyclones become upright allowing for intensification published in the Journal of Geophysical Research
Review of aircraft missions into Hurricane Earl
NOAA conducted 20 aircraft missions into Hurricane Earl in late August and early September. The series of flights over 12 days was the longest series of flights into one system that NOAA has conducted. We recently reviewed these flights, and the slides from the review can be found here. Flight tracks of all the NOAA … Continue reading Review of aircraft missions into Hurricane Earl
