Flight Plan |
Plan is to target the Eye-eyewall Mixing Module for either the second or third pass, if time allows. Plan would be to fly upwind around the eye to get more radar scans since we would be flying a little slower
|
|
Expendable Distribution |
Flight plan described in previous section. In addition, fixes each pass and NHC also requested RMW sondes in the NE and NW.
|
|
Preflight Weather Briefing |
From NHC discussion: “Larry currently has an annular structure, with a 60 n-mi diameter eye and a relatively thick eyewall. High-resolution visible imagery shows several meso-vortices rotating within the eye, which is typically observed in strong hurricanes. The upper-level outflow has become better defined over the western portion of the circulation, indicative of decreased shear in comparison to yesterday. The advisory intensity is kept at 105 kt, in reasonable agreement with the latest Dvorak estimates from TAFB and SAB.” Current satellite imagery:

Mission Summary |
This was a highly successful mission. A butterfly pattern was flown with two ALAMO floats released ahead of the motion after the 1st pass through the center. On the third pass, an Eye-Eyewall Mixing Module was flown which consisted of a clockwise circumnavigation of the eye and a dropsonde in a potential mesovortex. In addition to the standard pattern, three RMW sondes were launched and a center fix was made for each pass for NHC. The radar data was used for the 5 PM ET NHC forecast discussion to discuss surface winds, which we believe is a first. “During that pass through the hurricane, the aircraft tail Doppler radar measured winds of 121 kt at a height of 3 km in the northeastern eyewall, which equate to about 109 kt at the surface. Therefore, the initial intensity has been adjusted up to 110 kt for this advisory. A pair of dropsondes into the eye of Larry measured a minimum central pressure of 956 mb.” 21 total dropsondes were released (14 for EMC, 2 for NHC, 4 for HRD, 1 for ONR), as well as 2 AOML/PhOD ALAMO floats (both failed) and 8 NRL AXBTs (1 bad) |

Instrument Notes |
An issue with the MMR on N43. The Flight Director said that the one on N43 is worse than on N42. Surface roughness field is ok, but HWX and NAW are bad — lower than expected reflectivity on the MMR. |

Flight Plan |
The planned pattern is for a 70 nmi butterfly with a brief module northwest of the storm to release 2 Navy ALAMO floats (at a location 24 hours in advance of the passage of the storm center track). Altitude in pattern and for ALAMO releases will be 10 kft.
|
|
Expendable Distribution |
Dropsondes to be released at the endpoints (EMC), midpoints (EMC), center (EMC), and RMWs on each inbound and outbound (6 charged to EMC, the remainder to ONR TCRI). Another sonde will be released in combo with an ONR AXBT between the ALAMO releases. ONR AXBTs will be released at each endpoint, once in the center (if possible), and once between the 2 Navy ALAMO releases.
|
|
Preflight Weather Briefing |
As of the 2 PM EDT NHC advisory, Hurricane Sam is located near 12.9N / 47.6W, has an estimated max sustained winds of 105 kt, MSLP of 960 mb, and is moving west-northwest at 9 kt. Over the past 24 hours, Sam has continued to rapidly intensify. The inner core continues to gain symmetry as it is no longer somewhat constricted on the west side of the storm and there is a complete ring of deep convection around the center. The eye has also been progressively clearing over the past few hours. It’s possible the storm is continuing to intensify, though this mission will collect the first in-situ data from the center of the storm. The environment remains very favorable for rapid intensification, with possibly only a slight cool ocean eddy and eyewall replacement cycles being the limiting factor for further intensification today.

Mission Summary |
This flight perhaps captured the end of what has been a very impressive period of rapid intensification for Sam as the MSLP was consistently 943-945 mb. The peak surface winds were up above 140 kt (observed on the NE inbound and NW outbound), with some impressive dropsondes showing up to nearly 200 kt winds at 900 mb, and 162 kt surface winds in a SE eyewall sonde that translated to the NE quadrant. Convection was vigorous throughout the mission, with plenty of inner core lightning and graupel and turbulence reported by the crew. Dry air appears to be ~40 n mi outside of the core in the northwest quadrant which could be limiting convection. The mission successfully dropped almost all planned sondes, all planned ONR AXBTs, and the two Navy ALAMO floats, meeting all of the APHEX-AIPEX and ONR TCRI goals. An additional ADM-Aeolus validation module was planned on the fly as Aeolus passed just west of the storm around 2121Z; an improvised sonde was released from the P-3 at 2135Z in the Aeolus footprint, about 15 min after its passage. 34 total dropsondes released (31 of them good and transmitted; 21 charged to NWS, 12 charged to ONR, and 1 charged to HRD) 8 ONR AXBTs released; all good 2 Navy ALAMO floats deployed

Preflight Weather Briefing |
As of the 11 AM EDT NHC Advisory, Hurricane Sam was located near 13.9N / 50.2W, had an estimated max wind of 125 kt, MSLP of 943 mb, and was moving west-northwest at 7 kt. Since yesterday, it appears that the storm has more or less been in a steady state, though the inner core continues to exhibit an impressive ring of deep convection and clear eye. The environment continues to be favorable for the storm to maintain its intensity, and perhaps strengthen some (though it is fairly close to its maximum potential intensity), though eyewall replacement cycles are certainly possible and could temporarily weaken the storm. It’ll be interesting to see whether this flight observes secondary eyewall formation.
 
|
|
Instrument Notes |
All instruments up and functioning. WSRA received a software update to potentially fix a bad data processing from yesterday’s flight. |

The ring of intense convection surrounding the 15-n-mi-diameter eye has expanded in size over the past several hours, while cloud tops colder than -70C still completely surround the center. An earlier GMI microwave overpass revealed very strong eyewall convection tightly wrapped around the small eye, a feature oftentimes seen with intense hurricanes.

The first TDR analysis (below) shows an outer ring of vorticity at 2 and 5 km at 30 km from the center, suggesting that the SEF is forming. So we decided to drop the first RMW sonde on this inbound from the NE at 15 nmi (where the SEF may be) from the center, then keep the 2 RMW sondes. LPS is reporting an SEF feature on the MMR.

Mission Summary |
This mission captured secondary eyewall formation (SEF) as the storm was coming out of peak intensity (the 11 PM EDT NHC forecast discussion suggested an intensity of 135 kt, 929 mb based on the initial data from the first pass of the mission). The observations from the TDR, MMR, and flight level winds clearly indicated SEF formation at about 15-20 n mi from the center (though possibly already had started by the time the P-3 arrived in the storm). The storm is now on a weakening trend (perhaps as much as 14 mb increase in the central pressure, 943 mb by the end). The final satellite loops show the impact of the SEF and pending potential eyewall replacement cycle (ERC). There has been a dramatic warming of the inner central dense overcast (CDO) during the mission, especially on the western side of the inner core, and the eye that was so impressive earlier is filling in. By the second pass, one of the three planned RMW dropsonde releases were changed to be dropped near the radius of the SEF, which was of great interest to the ONR TCRI program, as well. One of the unique aspects of this flight versus other flights that have sampled SEFs is that the inner core was so small that the original eyewall and secondary eyewall were in range of the TDR on each pass; that will allow us to look in detail at the time evolution of the SEF process during the mission. So, overall, excellent data collection and now the question will be: does Sam complete an ERC? 34 dropsondes released (34 transmitted; 21 charged to NWS; 13 charged to ONR); 7 ONR AXBTs (all good; SSTs 27-28.5C)

Flight Plan |
The planned pattern is for a 90 n mi butterfly with an additional Gravity Wave Module to the NW at the completion of the pattern. Altitude will be 10 kft.
|
|
Expendable Distribution |
Dropsondes to be released at the endpoints (EMC), midpoints (EMC), center (EMC), and RMWs on each inbound and outbound (6 charged to EMC, the remainder to ONR TCRI). ONR AXBTs will be released at each endpoint, and once in the center (if possible).

Preflight Weather Briefing |
As of the 11 AM EDT NHC Advisory, Hurricane Sam was located near 13.9N / 50.2W, had an estimated max wind of 125 kt, MSLP of 943 mb, and was moving west-northwest at 7 kt. Since yesterday, it appears that the storm has more or less been in a steady state, though the inner core continues to exhibit an impressive ring of deep convection and clear eye. The environment continues to be favorable for the storm to maintain its intensity, and perhaps strengthen some (though it is fairly close to its maximum potential intensity), though eyewall replacement cycles are certainly possible and could temporarily weaken the storm. It’ll be interesting to see whether this flight observes secondary eyewall formation.
|

Instrument Notes |
All instruments up and functioning. WSRA received a software update to potentially fix a bad data processing from yesterday’s flight. |

5 PM NHC Advisory: 14.2N / 50.5W, 130 kt, 938 mb, moving northwest at 6 kt: “Sam has found a way to strengthen some more today. The ring of intense convection surrounding the 15-n-mi-diameter eye has expanded in size over the past several hours, while cloud tops colder than -70C still completely surround the center. An earlier GMI microwave overpass revealed very strong eyewall convection tightly wrapped around the small eye, a feature oftentimes seen with intense hurricanes.

|
| Flight Plan | This is an HRD-tasked research mission into Hurricane Ida in collaboration with ONR/TCRI. The planned flight track calls for flying a rotated figure-4 with possible additions of a microphysical spiral module in stratiform precipitation between points 2 and 3 along with a convective burst module. |
| Expendable Distribution | Endpoint, midpoint, eyewall/RMW drops, center drops. AXBTs planned at points 1, 3, 6, and 7 along with one center pass as shown above. |
| Preflight Weather Briefing | Ida has strengthened into a hurricane through the day as it approaches the western tip of Cuba. As of the 1900 UTC advisory, NHC has Ida at 65 kt with a minimum central pressure of 987 mb and moving NW at 13 kt. Ida is currently passing over the Isle of Youth and will be approaching the southern coast of the Cuban mainland near the time that the P-3 is reaching the storm.
The NHC forecast calls for Ida to maintain hurricane strength as it passes over Cuba and potentially rapidly intensify over the Gulf of Mexico before making landfall along the northern Gulf coast. |

Time [UTC] |
Event |
| 1955 | Takeoff from Lakeland |
| 2030 | Interesting evolution in the cloud structure on IR as Ida’s central dense overcast (CDO) approached the northern edge of Cuba. It appears to go from a well organized CDO to being very ragged on the northern half of the storm. Curious if the mountains along the northern coast of Cuba disrupted the circulation enough to cause this collapse. |
| 2103 | Discussing possible targets for microphysics spiral. There is a potential that stratiform precip is present on the SE side (outbound leg 1) that could be a target. Another option is between pts 2 and 3, likely on the N side of Cuba. Plan is to assess on the outbound pass to determine if it’s worth backtracking for the spiral near the center on the SE side. |
| 2106 | Arrived at initial point (IP) |
| 2114 | Rob noted stratiform precip present on TDR off their left wing |
| 2122 | Slight deviation around convection |
| 2124 | Jun noted RMW sonde hasd 66 kt surface wind |
| 2130 | Rob noted that they broke out into the clear with a stratus deck below and above them. This coincides with them exiting the region of coldest cloud tops. |
| 2133 | TDR Xchat channel reported antenna packet communication dead. |
| 2136 | No RMW or 50 km drops since they would have been over land |
| 2137 | Todd is rebooting the TDR |
| 2139 | TDR back up |
| 2140 | 2-min HRD center: 22.41N, 83.85W (6.66 nmi SE of marked center). Lowest extrap pressure of 988 mb and min wind speed 14.641 kt. |
| 2158 | EP leg 1 (pt 2). Turning back inbound to target the region of stratiform precip for the microphysics spiral. |
| 2159 | John had Rob close the loop_check_sweeps window to see if that was causing a backlog that was disrupting the xchat/comms with the radar workstations ability to sync files. |
| 2217 | Beginning microphysics spiral in region east of the center |
| 2232 | Top of the microphysics spiral at 22 kft. Rob noted that there wasn’t much precip at the higher altitudes. We had discussions about doing a second microphysics spiral to the NW of this location, but decided to proceed to pt3 to allow for more options as the flight progresses and to get the second pass in and hopefully catch a convective burst (CB) as it comes offshore on the W side of the eye. |
| 2249 | Finished descending back to 10 kft and proceeding to pt 3 |
| 2301 | Some lightning showing up in the CB that has been occurring to the W of the eye. It’s definitely bursting! |
| 2310 | Inbound at pt 3 |
| 2316 | Tracking slightly right of planned track on leg 2 due to Havana air space |
| 2328 | No RMW, quarter pt, or center due to land on this inbound leg |
| 2335 | Rob noted a closed eyewall, almost on MMR. Kind of a banded structure. |
| 2337 | Marked center. 2-min HRD center: 22.48N 83.41W. 5.74 n mi NW of marked center. Lowest extrap pressure: 987 mb minimum wind speed: 11.687 kt No RMW drop outbound as they were still over land |
| 2343 | Rob noted the flight level winds were very asymmetric on this pass. About a 25-30 kt difference between NE and SW |
| 2347 | We will not be able to drop a BT in the center, so we are trying to decide where we want to drop the 5th BT. Rob’s suggestion was midpoint outbound to the N. Jun thought that was a good plan |
| 2349 | Rob said we will have about 20 mins for a CB module. Trying to determine potential targets. Discussion about the south side of the eyewall. Cold cloud tops on IR imagery have expanded quite a bit so it’s hard to tell from the ground where a good CB target would be anymore. Will have to rely on MMR on this pass to see if there is anything to target. |
| 2359 | Rob talked to Nikki and they were wondering if we could fly parallel to the CB in the SW eyewall inside the eye. The legs would be pretty short ~8-10 n mi. John G. said that you probably want at least ~30 n mi to get enough overlap between the fore and aft beams. You need 2 mins on each side of the length that you want. |
| 0006 | End of leg 2, pt 4 |
| 0009 | Rob is thinking about doing radial pennies, 30 n mi in length on the N side outbound. So, go out initially 30 n mi from the start of the leg, turn around and come back 30 n mi and then resume outbound and the remainder of the pattern. Right now there isn’t much showing on Cuba radar or IR imagery to indicate a good target on the N side. |

| 0036 | Rob noted that there is nothing showing up on this inbound leg in terms of convection. Just a thin line of returns on the nose, broken on the MMR. Stratiform east of them over Cuba. Seeing some more on the east side further north. |
| 0040 | Latest frame of Cuba radar looks like there might be something bursting on the N side. |
| 0042 | Rob noted a feature showing up on the MMR ~40 n mi N of them, which is the distance I was noting as well for the feature on Cuban radar. Rob noted another feature ~30 n mi NNE of their position. The feature to their N looks like a better target for a CB module. Can also do drops on that one since it is farther offshore. |
| 0045 | The CB on the N side looks like it might be trying to wrap into the eyewall. |
| 0046 | Mark center |
| 0050 | Turning to 315 degree heading to start the CB module on the N side of the eye just off the N shore of Cuba. Will go for 30 n mi outbound then back, then resume pattern |
| 0052 | Rob noted that this feature is pretty narrow. He said it does look like it might be trying to wrap into the eyewall, but it’s kind of localized on the MMR right now. They are seeing red on the nose radar. |
| 0054 | Rob noted echo tops ~8-12 km, so moderately deep convection. |
| 0055 | Some echo tops up to 14-15 km now. |
| 0057 | Rob is wondering if we should do a third pass back out through this feature on the same radial then resume pattern. |
| 0059 | Turning back inbound for a second pass through CB. |
| 0100 | Climbing to 12 kft because AF is entering the storm |
| 0101 | Trying to decide if it’s better to get TDR coverage back on the S-N radial or more beneficial to get the 3rd pass through the CB. Cold cloud tops are starting to show up in IR imagery near this CB that we are targeting. Rob thinks the CB is growing, so we decided that since this was a research mission it would be more beneficial to do the 3rd pass through the CB. |
| 0104 | Rob noted that the CB looks more impressive on nose radar |
| 0105 | Having some comms dropouts |
| 0110 | Turned back outbound to 315 degree heading for 3rd pass through CB. |
| 0114 | Just noticed HDOBs are delayed coming off the plane. Last message on the ground is from 2314Z. TDR is also not coming off plane |
| 0119 | End of 3rd pass through CB |
| 0125 | Paralleling the CB somewhat while heading to pt 6 |
| 0129 | Midpoint sonde, combo drop |
| 0130 | GOES-16 IR imagery showing cold cloud tops developing in region of CB sampling |
| 0132 | Rob checked the WMM app and said there are a lot of messages pending being sent off the plane, so it seems like comms are just being very slow |
| 0133 | Todd made a change to a config file and messages should be coming off now. |
| 0140 | Turning downwind at pt 6 |
| 0142 | Turning right a little for avoidance |
| 0212 | Turning inbound at pt 7 |
| 0224 | HDOBs appear to have caught up arriving on the ground |
| 0234 | They are approaching the CB that they flew earlier. Rob said they have the surface roughness mode on right now, but it doesn’t look that threatening on the nose radar. Just yellows. The tail looks mostly stratiform. Cuba radar was indicating it may have become stratiform, but we weren’t sure if that was just because of it being at the edge of the radar range. |
| 0237 | TDR data trickling off slowly. John G. said we will probably only get TDR data from two passes off the plane. |
| 0238 | Rob noted expansive echos up to 15 km on TDR to their right. |
| 0239 | Winds are sending them south. They are doing some “light” hunting. Rob noted this storm has been difficult to fix the whole flight. |
| 0241 | Rob said that the MMR surface roughness is really interesting. Almost two centers, one behind and one in front of them. Seems like a new eye might be trying to form. MMR shows interesting structure. |
| 0248 | Rob said the MMR looks more reasonable now, like they’re in the center just barely offshore |
| 0251 | Rob notes that that it’s almost like it’s getting better organized as it emerges offshore |
| 0253 | RMW sonde on the E side |
| 0259 | Just noticed that after they climbed to 12 kft, the SFMR was being /// in the HDOBs. The altitude threshold has not been removed and they were exceeding the 12.5 kft radar altitude threshold. After chatting with Ashley, we will try to go to 8 kft when necessary rather than 12 kft on future flights into Ida. |
| 0309 | Endpoint, pt 8. Heading back to LAL |
| 0341 | TDR turned off |

| Mission Summary | We successfully flew a rotated figure-4 pattern along with a microphysics spiral module on the east side of the storm south of Cuba and a convective burst module during the third leg on the N side of Cuba. Throughout the flight, we sampled the storm before making landfall on the south coast of Cuba, while it was over Cuba, and after it emerged off the north coast of Cuba. The evolution of the structure throughout this flight was quite interesting as the interactions with Cuba seemed to disrupt the low level circulation, but the convection and upper levels seemed to be maintained well enough that it did not hinder the storm’s evolution significantly. The 0300 UTC NHC advisory had Ida at a minimum SLP of 989 mb and max sustained winds of 70 kts.
IR imagery throughout the flight showed the CDO collapse on the north side as Ida approached Cuba and began to redevelop as it crossed over Cuba. Another interesting observation is that in all of the TDR analyses, the strongest inflow was depicted as occurring on the north side of the circulation. However, I wonder if this could be an artifact of land in the TDR data. Final plot of HDOBs: Expendables deployed: 25 dropsondes (10 HRD, 15 ONR); 5 NRL AXBTs |
