Noaa hurricane track full#
Reports from AOML PHOD showed that Ida travelled over several Argo floats during its full track and over one hurricane glider in the northern Gulf of Mexico. The data collected during these flights were very important for better understanding rapid intensification of tropical cyclones. There were multiple missions flying into the eye of Hurricane Ida as it approached the Louisiana coast on August 29th. During this flight the crew sampled a newly forming region of thunderstorms on the north side of Cuba as Ida was coming offshore to see how this new region would impact the eyewall development. The goals of the first mission were to work on Convective Burst Structure and Evolution and the Stratiform Spiral Module all in collaboration with ONR and TCRI. During the second CEPHEX mission on August 26th, the crew flew another ADM-Aeolus transect where the images showed data from HALO (High Altitude Lidar Observatory) and HAMSR.ĪPHEX missions into Hurricane Ida began on August 27th and went until August 29th. On this mission, CEPHEX also completed an ADM-Aeolus underflight. Dropsondes were deployed and detected significant dropouts below 850 mb. The CPHEX mission carried out on August 24th followed a “lawnmower” track which sampled convection in the southern Caribbean associated with AL99, which became Ida. Hurricane Ida, one of the most notable storms of the 2021 hurricane season, was monitored by both CPHEX and APHEX missions spanning from August 24th to August 29th.
169 GPS dropsondes / 160 transmitted to the GTS.Nine NOAA and Nine Air Force operationally tasked missions by NHC into Hurricane Ida. Rather than finding a clear center, data showed that the storm had an elongated circulation center or wave axis that made it challenging to fix an actual closed center. The goal of the second flight, which flew on August 15th, was to identify the center of circulation of Hurricane Grace. The “southern” low-level vorticity center was actually aligned with the midlevel center. There were a total of 30 dropsondes and five airborne expendable bathythermographs (AXBTs) deployed.ĭuring the first flight on August 14th, an interesting observation was that the disturbance appeared to exhibit multiple vorticity centers at low-levels. Multiple observation systems were deployed during the missions for TS Grace. 32 TDR analyses transmitted to EMC & NHCĪOML HRD missions for Tropical Storm (TS) Grace began on August 14th and continued until August 19th, 2021.218 GPS dropsondes transmitted to the GTS.8 P-3 missions, 3 G-IV missions (2 NHC, 6 EMC, 3 HRD).Nine Air Force missions and eleven NOAA missions into Hurricane Grace.
