Hurricane hunters, typhoon hunters, or cyclone hunters are aircrews that fly into tropical cyclones to gather weather data. In the United States, the organizations that fly these missions are the United States Air Force Reserve's 53rd Weather Reconnaissance Squadron and the National Oceanic and Atmospheric Administration's Hurricane Hunters. Such missions have also been flown by Navy units and other Air Force and NOAA units. Other organizations also fly these missions, such as Government Flying Service Hong Kong.

The first crewed flight into a hurricane happened in 1943 when a pilot-trainer flew into a Category 1 hurricane near Galveston, Texas on a bet. [1]

In the past, before satellites were used to find tropical storms, military aircraft flew routine weather reconnaissance tracks to detect formation of tropical cyclones. While modern satellites have improved the ability of meteorologists to detect cyclones before they form, only aircraft are able to measure the interior barometric pressure of a hurricane and provide accurate wind speed data, information needed to accurately predict hurricane development and movement.

Units

USAFR 53rd WRS

The Air Force Reserve 53rd Weather Reconnaissance Squadron, the world's only operational military weather reconnaissance unit, is based at Keesler Air Force Base in Biloxi, Mississippi; most weather recon flights originate there. The term "hurricane hunters" was first applied to its missions in 1946.

The USAFR hurricane hunters fly weather missions in an area midway through the Atlantic Ocean to the Hawaiian Islands, and have on occasion flown into typhoons in the Pacific Ocean and gathered data in winter storms.

The 53rd WRS hurricane hunters operate ten Lockheed WC-130J aircraft, which fly directly into hurricanes, typically penetrating the hurricane's eye several times per mission at altitudes between 500 feet (150 m) and 10,000 feet (3,000 m).

NOAA Hurricane Hunters

The civilian and NOAA Corps crew members of the NOAA Hurricane Hunters, originally based at the Aircraft Operations Center at MacDill AFB, in Tampa, Florida, mainly perform surveillance, research, and reconnaissance with highly instrumented aircraft including airborne Doppler weather radar measurements in both Atlantic and Pacific storms. In June 2017 [2] [3] the Hunters moved into a new facility at Lakeland Linder International Airport in Lakeland, Florida, having been at MacDill since 1993. They fly two Lockheed WP-3D Orion aircraft, heavily instrumented flying laboratories modified to take atmospheric and radar measurements within tropical cyclones and winter storms, and a G-IV Gulfstream high-altitude jet above 41,000 feet (12 km) to document upper- and lower-level winds that affect cyclone movement. The computer models that forecast hurricane tracks and intensity mainly use G-IV dropsonde data collected day and night in storms affecting the United States.

On September 27, 2024, NOAA announced it had awarded a contract to Lockheed Martin Aeronautics for two Lockheed Martin C-130J Super Hercules aircraft configured for use as hurricane hunters to replace its aging WP-3D Orions, with service entry planned in 2030. [4]

Government Flying Service Hong Kong

Since 2009 the Government Flying Service of Hong Kong (GFS) have conducted regular flight data collection in cooperation with the Hong Kong Observatory. In 2011, the cooperation between GFS and the Observatory extended to reconnaissance flights to capture weather data for tropical cyclones over the South China Sea. [5] In September 2016 they introduced the dropsonde system, which collects extra meteorological data on tropical cyclones to enhance the monitoring of typhoons. [6]

Among the types of aircraft that have been used to investigate hurricanes, are an instrumented Lockheed U-2 flown in Hurricane Ginny during the 1963 Atlantic hurricane season. Other types include the A-20 Havoc, 1944; B-24, 1944–1945; B-17, 1945–1947; B-25, 1946–1947; B-29, 1946–1947. WB-29, 1951–1956; WB-50, 1956–1963; WB-47, 1963–1969; WC-121N 1954–1973; WC-130A, B, E, H, 1965–2012.

The idea of aircraft reconnaissance of hurricane storm trackers was put forth by Captain W. L. Farnsworth of the Galveston Commercial Association in the early 1930s. Supported by the United States Weather Bureau, the "storm patrol bill" passed both the United States Senate and United States House of Representatives on June 15, 1936. [7]

1935 Labor Day Hurricane

The first time a reconnaissance flight took place with the sole purpose of locating a hurricane was during the 1935 Great Labor Day Hurricane, which would later become the strongest storm to ever impact the U.S.

On September 1, the storm moved through The Bahamas where it was estimated to be at hurricane strength. As a result, ships began to avoid the Florida Straits, depriving the Weather Bureau of valuable information. This led to confusion as the Weather Bureau believed it would continue on its westward path and make landfall in Cuba while the Cuba weather service didn't see any evidence for this.

On September 2, a pilot flying over the Florida Keys noticed a large cloud mass to the east and more north than it should have been. The Cuban weather service requested a plane to be sent up to find the storm, with Captain Leonard Povey volunteering. After circling, but not penetrating (his plane had an open cockpit), the storm, he confirmed the storm was located more north than originally thought and actually heading northeast. This was relayed to the Weather Bureau, which immediately put warnings out for the Florida Keys. The storm would make landfall later that day.

Capt. Povey urged Congress and the Weather Bureau to implement full-time reconnaissance planes, but to no avail. A plan was laid out to use Coast Guard cutters, but was never implemented. [8]

1943 Surprise Hurricane

The 1943 Surprise Hurricane, which struck Houston, Texas, during World War II, marked the first intentional meteorological flight into a hurricane. It started with a bet.

That summer, British pilots were being trained in instrument flying at Bryan Field. When they saw that the Americans were evacuating their AT-6 Texan trainers in the face of the storm, they began questioning the construction of the aircraft. Lead instructor Colonel Joe Duckworth took one of the trainers out and flew it straight into the eye of the storm. After he returned safely with navigator Lt. Ralph O'Hair, the base's weather officer, Lt. William Jones-Burdick, took over the navigator's seat and Duckworth flew into the storm a second time. [9] [10]

This flight showed that hurricane reconnaissance flights were possible, and further flights continued occasionally. In 1946, the moniker "Hurricane Hunters" was first used, and the Air Force and now Air Force Reserve have used it ever since. The flights demonstrated that hurricane reconnaissance flights were feasible. [11] [12]

The United States Navy's VW-4 / WEARECORON FOUR Weather Reconnaissance Squadron Four, "Hurricane Hunters" was the seventh U.S. Navy squadron dedicated to weather reconnaissance. They flew several types of aircraft, but the WC-121N "Willy Victor" was the aircraft most often associated with flying into the "eye of the storm." The squadron operated WC-121s between late 1954 and 1972. [13] VW-4 lost one aircraft with its crew of 11 in a penetration of Hurricane Janet in 1955, [14] and another to severe damage in a storm, but the severely damaged Willy Victor (MH-1) brought her crew home, although she never flew again. During 1973–1975, VW-4 operated the turbine-propeller Lockheed WP-3A Orion.

Hurricane Katrina

The landfall of Hurricane Katrina on 29 August 2005 devastated Keesler Air Force Base, home of the 53rd WRS. The equipment and personnel of the squadron were flying out of Dobbins Air Reserve Base near Atlanta. Despite heavy equipment losses, the squadron never missed a mission from the National Hurricane Center. The 53rd has since returned to Keesler.

Project Stormfury was an attempt to weaken tropical cyclones by flying aircraft into them and seeding them with silver iodide. The project was run by the United States Government from 1962 to 1983. The hypothesis was that the silver iodide would cause supercooled water in the storm to freeze, disrupting the inner structure of the hurricane, and this led to seeding several Atlantic hurricanes. However, it was later shown that this hypothesis was incorrect. It was determined that most hurricanes do not contain enough supercooled water for cloud seeding to be effective. Additionally, researchers found that unseeded hurricanes often undergo the same structural changes that were expected from seeded hurricanes. This finding called Stormfury's successes into question, as the changes reported now had a natural explanation.

The Navy had been using B-24s with only minor modifications as the PB4Y-1 Liberator, and along with maritime patrol Liberators used by RAF Coastal Command, this type of patrol plane was proven successful. A fully navalized design was desired, and Consolidated developed a dedicated long-range patrol bomber in 1943, designated PB4Y-2 Privateer. In 1951, the type was redesignated P4Y-2 Privateer. A further designation change occurred in September 1962, when the remaining US Navy Privateers were redesignated QP-4B.

The 1971 Pacific hurricane season began on May 15, 1971 in the eastern Pacific, and on June 1, 1971 in the Central Pacific ; both ended on November 30, 1971. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. It was the first year that continuous Weather satellite coverage existed over the entire Central Pacific. As such, this season is often viewed as the start year for modern reliable tropical cyclone data in the Pacific Ocean.

Hurricane Carrie was a deadly and long-lived Category 4 major hurricane which was the strongest tropical cyclone of the 1957 Atlantic hurricane season and one of the longest-lasting tropical cyclones in the North Atlantic basin. The third named storm and second hurricane of the year, Carrie formed from an easterly tropical wave off the western coast of Africa on September 2, a type of tropical cyclogenesis typical of Cape Verde-type hurricanes. Moving to the west, the storm gradually intensified, reaching hurricane strength on September 5. Carrie intensified further, before reaching peak intensity on September 8 as a Category 4 hurricane with maximum sustained winds of 140 mph (220 km/h) in the open Atlantic Ocean. The hurricane curved northwards and fluctuated in intensity as it neared Bermuda on September 14. However, Carrie passed well north of the island and turned to the northeast towards Europe. Weakening as it reached higher latitudes, the storm transitioned into an extratropical cyclone on September 23, prior to affecting areas of the British Isles, and subsequently dissipated on September 28.

<span class="mw-page-title-main">Typhoon Bess (1974)</span> Pacific typhoon in 1974

Typhoon Bess, known in the Philippines as Typhoon Susang, was responsible for the disappearance of a United States Air Force weather reconnaissance aircraft. Developing out of a poorly organized system on October 8 to the east of the Philippines, Bess featured two centers of circulation. Initially the southern low was monitored; however, a low to the north soon became the dominant center. Tracking generally west-northwestward, the storm gradually intensified before striking northern Luzon as a minimal typhoon on October 11. Temporary weakening took place due to interaction with land. After moving back over water the following morning, Bess regained typhoon intensity. This was short-lived though, as conditions surrounding the cyclone soon caused it to weaken. Now moving due west, the weakening storm eventually struck Hainan Island as a tropical storm on October 12 before diminishing to a tropical depression. The depression briefly moved back over water before dissipating in northern Vietnam on October 14.

<span class="mw-page-title-main">Tropical cyclone observation</span>

Tropical cyclone observation has been carried out over the past couple of centuries in various ways. The passage of typhoons, hurricanes, as well as other tropical cyclones have been detected by word of mouth from sailors recently coming to port or by radio transmissions from ships at sea, from sediment deposits in near shore estuaries, to the wiping out of cities near the coastline. Since World War II, advances in technology have included using planes to survey the ocean basins, satellites to monitor the world's oceans from outer space using a variety of methods, radars to monitor their progress near the coastline, and recently the introduction of unmanned aerial vehicles to penetrate storms. Recent studies have concentrated on studying hurricane impacts lying within rocks or near shore lake sediments, which are branches of a new field known as paleotempestology. This article details the various methods employed in the creation of the hurricane database, as well as reconstructions necessary for reanalysis of past storms used in projects such as the Atlantic hurricane reanalysis.

The Hurricane Research Division (HRD) is a section of the Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Florida, and is the U.S. National Oceanic and Atmospheric Administration's (NOAA) focus for tropical cyclone research. The thirty member division is not a part of the National Hurricane Center but cooperates closely with them in carrying out its annual field program and in transitioning research results into operational tools for hurricane forecasters. HRD was formed from the National Hurricane Research Laboratory in 1984, when it was transferred to AOML and unified with the oceanographic laboratories.

Typhoon Nora, known in the Philippines as Typhoon Luming, is tied for the fourth-most intense tropical cyclone on record. Originating from an area of low pressure over the western Pacific, Nora was first identified as a tropical depression on October 2, 1973. Tracking generally westward, the system gradually intensified, attaining typhoon status the following evening. After turning northwestward, the typhoon underwent a period of rapid intensification, during which its central pressure decreased by 77 mb in 24 hours. At the end of this phase, Nora peaked with winds of 295 km/h (185 mph) and a pressure of 875 mb, making it the most-intense tropical cyclone on record at the time; however, this pressure has since been surpassed by Typhoon June, Typhoon Tip and Hurricane Patricia. The typhoon subsequently weakened and turned northwestward as it approached the Philippines. After brushing Luzon on October 7, the system passed south of Taiwan and ultimately made landfall in China on October 10. Once onshore, Nora quickly weakened and dissipated the following day.

The AN/APS-20 was an airborne early warning, anti-submarine, maritime surveillance and weather radar developed in the United States in the 1940s. Entering service in 1945, it served for nearly half a century, finally being retired in 1991. Initially developed at Massachusetts Institute of Technology (MIT) under Project Cadillac, the radar was developed to be carried by aircraft to extend the sensor range of ships by placing a radar at altitude. Although developed for carrier-borne operation, first being installed in the single-engined General Motors TBM-3W Avenger, it was also used in larger four-engined airframes, the last being a fleet of Avro Shackleton AEW.2 which were converted from maritime patrol aircraft. Similarly, although developed for detecting aircraft, it saw extensive service in anti-submarine and maritime patrol roles and was one of the first radars to be used in researching extreme weather like hurricanes by agencies like the Environmental Science Services Administration (ESSA). As well as the United States, the radar was used by a large number of services in other countries, including the French Navy, Japan Maritime Self-Defense Force (JMSDF), Royal Air Force (RAF) and Royal Canadian Air Force (RCAF). Early versions of the radar could see a low-flying aircraft at 65 nautical miles and a ship at 200 nautical miles. This was improved, so that later versions had a range against aerial targets of 115 nautical miles.
