Weather ship

Weather ship
The weather ship MS Polarfront at sea.

A weather ship was a ship stationed in the ocean as a platform for surface and upper air meteorological observations for use in weather forecasting. They were primarily located in the north Atlantic and north Pacific oceans, reporting via radio. In addition to their weather reporting function, these vessels aided in search and rescue operations, supported transatlantic flights,[1][2] acted as research platforms for oceanographers, monitored marine pollution, and aided weather forecasting both by weather forecasters and within computerized Atmospheric models.

The idea of a stationary weather ship was proposed as early as 1921 by Météo-France to help support shipping and the coming of transatlantic aviation. They were used during World War II but had no means of defense, which led to the loss of several ships and many lives. On the whole, the establishment of weather ships proved to be so useful during World War II for Europe and North America that the International Civil Aviation Organization (ICAO) established a global network of weather ships in 1948, with 13 to be supplied by Canada, the United States, and Europe. This number was eventually negotiated down to nine. The agreement of the use of weather ships by the international community ended in 1985.

Weather ship observations proved to be helpful in wind and wave studies, as commercial shipping tended to avoid weather systems for safety reasons, whereas the weather ships did not. They were also helpful in monitoring storms at sea, such as tropical cyclones. Beginning in the 1970s, their role was largely superseded by weather buoys because of the ships' significant cost. The removal of a weather ship became a negative factor in forecasts leading up to the Great Storm of 1987. The last weather ship was Polarfront, known as weather station M ("Mike"), which was removed from operation on January 1, 2010. Weather observations from ships continue from a fleet of voluntary merchant vessels in routine commercial operation.

Function

Weather ship locations in the northern Atlantic ocean

The primary purpose of an ocean weather vessel was to take surface and upper air weather measurements, and report them via radio at the synoptic hours of 0000, 0600, 1200, and 1800 Universal Coordinated Time (UTC). Weather ships also reported observations from merchant vessels, which were reported by radio back to their country of origin using a code based on the 16-kilometer (9.9 mi) square in the ocean within which the ship was located. The vessels were involved in search and rescue operations involving aircraft and other ships. The vessels themselves had search radar and could activate a homing beacon to guide lost aircraft towards the ships' known locations. Each ship's homing beacon used a distinctly different frequency.[3] In addition, the ships provided a platform where scientific and oceanographic research could be conducted. The role of aircraft support gradually changed after 1975, as jet aircraft began using cross polar routes.[4] By 1982, the ocean weather vessel role had changed too, and the ships were used to support short range weather forecasting, in numerical weather prediction computer programs which forecast weather conditions several days ahead, for climatological studies, marine forecasting, and oceanography, as well as monitoring pollution out at sea. At the same time, the transmission of the weather data using Morse code was replaced by a system using telex-over-radio.[5]

The director of France's meteorological service, Météo-France, proposed the idea of a stationary weather ship in 1921 in order to aid shipping and the coming of transatlantic flights.[9] Another early proposal for weather ships occurred in connection with aviation in August 1927, when the aircraft designer Grover Loening stated that "weather stations along the ocean coupled with the development of the seaplane to have an equally long range, would result in regular ocean flights within ten years."[15] During 1936 and 1937, the British Meteorological Office (Met Office) installed a meteorologist aboard a North Atlantic cargo steamer to take special surface weather observations and release pilot balloons to measure the winds aloft at the synoptic hours of 0000, 0600, 1200, and 1800 UTC. In 1938 and 1939, France established a merchant ship as the first stationary weather ship, which took surface observations and launched radiosondes to measure weather conditions aloft.[4]

Starting in 1939, United States Coast Guard vessels were being used as weather ships to protect transatlantic air commerce, as a response to the crash of a Pan American World Airways aircraft during a transpacific flight in 1938.[2][9] The Atlantic Weather Observation Service was authorized by President Franklin Delano Roosevelt on January 25, 1940.[16] The Germans began to use weather ships in the summer of 1940. However, three of their four ships had been sunk by November 23, which led to the use of fishing vessels for the German weather ship fleet. Their weather ships were out to sea for three to five weeks at a time and German weather observations were enciphered using Enigma machines.[17] By February 1941, five 327-foot (100 m) United States Coast Guard cutters were used in weather patrol, usually deployed for three weeks at a time, then sent back to port for ten days. As World War II continued, the cutters were needed for the war effort and by August 1942, six cargo vessels had replaced them. The ships were defenseless, which led to the loss of the USCGC Muskeget (WAG-48) with 121 aboard on September 9, 1942. In 1943, the United States Weather Bureau recognized their observations as "indispensable" during the war effort.[2]

The flying of fighter planes between North America, Greenland, and Iceland led to the deployment of two more weather ships in 1943 and 1944. Great Britain established one of their own 80 kilometres (50 mi) off their west coast. By May 1945, frigates were used across the Pacific for similar operations. Weather Bureau personnel stationed on weather ships were asked voluntarily to accept the assignment. In addition to surface weather observations, the weather ships would launch radiosondes and release pilot balloons, or PIBALs, to determine weather conditions aloft. However, after the war ended, the ships were withdrawn from service, which led to a loss of upper air weather observations over the oceans.[4] Due to its value, operations resumed after World War II as a result of an international agreement made in September 1946, which stated that no fewer than 13 ocean weather stations would be maintained by the Coast Guard, with five others maintained by Great Britain and two by Brazil.[2]

History of the fleet

Late 1940s

The establishment of weather ships proved to be so useful during World War II that the International Civil Aviation Organization (ICAO) had established a global network of 13 weather ships by 1948, with seven operated by the United States, one operated jointly by the United States and Canada, two supplied by the United Kingdom, one maintained by France, one a joint venture by the Netherlands and Belgium, and one shared by the United Kingdom, Norway, and Sweden.[1] The United Kingdom used Royal Navy corvettes to operate their two stations, and staffed crews of 53 Met Office personnel. The ships were out at sea for 27 days, and in port for 15 days. Their first ship was deployed on July 31, 1947.[4]

During 1949, the Weather Bureau planned to increase the number of United States Coast Guard weather ships in the Atlantic from five at the beginning of the year to eight by its end.[18] Weather Bureau employees aboard the vessels worked 40 to 63 hours per week.[19] Weather ship G ("George") was dropped from the network on July 1, 1949, and Navy weather ship "Bird Dog" ceased operations on August 1, 1949.[8] In the Atlantic, weather vessel F ("Fox") was discontinued on September 3, 1949, and there was a change in location for ships D ("Dog") and E ("Easy") at the same time.[7] Navy weather ship J ("Jig") in the north-central Pacific ocean was placed out of service on October 1, 1949.[20] The original international agreement for a 13 ship minimum was later amended downward. In 1949, the minimum number of weather ships operated by the United States was decreased to ten, and in 1954 the figure was lowered again to nine, both changes being made for economic reasons.[21] Weather vessel O ("Oboe") entered the Pacific portion of the network on December 19, 1949. Also in the Pacific, weather ship A ("Able") was renamed ship P ("Peter") and moved 200 miles (320 km) to the east-northeast in December 1949, while weather vessel F ("Fox") was renamed N ("Nan").[10]

1950s

Location of weather ships in the northern Pacific ocean

Weather ship B ("Baker"), which had been jointly operated by Canada and the United States, became solely a United States venture on July 1, 1950. The Netherlands and the United States began to jointly operate weather ship A ("Able") in the Atlantic on July 22, 1950. The Korean War led to the discontinuing of weather vessel O ("Oboe") on July 31, 1950 in the Pacific, and ship S ("Sugar") was established on September 10, 1950.[6] Weather ship P's ("Peter") operations were taken over by Canada on December 1, 1950, which allowed the Coast Guard to begin operating station U ("Uncle") 2,000 kilometres (1,200 mi) west of northern Baja California on December 12, 1950. As a result of these changes, ship N ("Nan") was moved 400 kilometres (250 mi) to the southeast on December 10, 1950.[22]

Responsibility for weather ship V ("Victor") transferred from the United States Navy to the United States Coast Guard and Weather Bureau on September 30, 1951.[23] On March 20, 1952, Vessels N ("November") and U ("Uncle") were moved 32 kilometres (20 mi) to 48 kilometres (30 mi) to the south to lie under airplane paths between the western United States coast and Honolulu, Hawaii.[13] Weather vessel Q ("Quebec") began operation in the north-central Pacific on April 6, 1952,[11] while in the western Atlantic, the British corvettes used as weather ships were replaced by newer Castle-class frigates between 1958 and 1961.[4]

1960s

In 1963, the entire fleet won the Flight Safety Foundation award for their distinguished service to aviation.[4] In 1965, there were a total of 21 vessels in the weather ship network. Nine were from the United States, four from the United Kingdom, three from France, two from the Netherlands, two from Norway, and one from Canada. In addition to the routine hourly weather observations and upper air flights four times a day, two Russian ships in the northern and central Pacific ocean sent meteorological rockets up to a height of 80 kilometres (50 mi). For a time, there was a Dutch weather ship stationed in the Indian Ocean. The network left the Southern Hemisphere mainly uncovered.[21] South Africa maintained a weather ship near latitude 40° South, longitude 10° East between September 1969 and March 1974.[24]

Fading use

When compared to the cost of unmanned weather buoys, weather ships became expensive,[25] and weather buoys began to replace United States weather ships in the 1970s.[26] Across the northern Atlantic, the number of weather ships dwindled over the years. The original nine ships in the region had fallen to eight after ocean vessel C ("Charlie") was discontinued by the United States in December 1973.[27] In 1974, the Coast Guard announced plans to terminate all United States stations, and the last United States weather ship was replaced by a newly-developed weather buoy in 1977.[9]

A new international agreement for ocean weather vessels was reached through the World Meteorological Organization in 1975, which eliminated Ships I (India) and J (Juliett), and left ships M ("Mike"), R ("Romeo"), C ("Charlie"), and L ("Lima") across the northern Atlantic, with the four remaining ships in operation through 1983.[28] Two of the British frigates were refurbished, as there was no funding available for new weather ships. Their other two ships were retired, as one of the British run stations was eliminated in the international agreement.[4] In July 1975, the Soviet Union began to maintain weather ship C ("Charlie"), which it would operate through the remainder of the 1970s and 1980s.[27] The last two British frigates were retired from ocean weather service by January 11, 1982, but the international agreement for weather ships was continued through 1985.[5]

Because of high operating costs and budget issues, weather ship R ("Romeo") was recalled from the Bay of Biscay before the deployment of a weather buoy for the region. This recall was blamed for the minimal warning given in advance of the Great Storm of 1987, when wind speeds of up to 149 kilometres per hour (93 mph) caused extensive damage to areas of southern England and northern France.[29] The last weather ship was Polarfront, known as weather station M ("Mike") at 66°N, 02°E, run by the Norwegian Meteorological Institute. Polarfront was withdrawn operation on January 1, 2010.[30] Despite the loss of designated weather ships, weather observations from ships continue from a fleet of voluntary merchant vessels in routine commercial operation,[31] whose number has decreased since 1985.[32]

Use in research

Beginning in 1951, British ocean weather vessels began oceanographic research, such as monitoring plankton, casting of drift bottles, and sampling seawater. In July of 1952, as part of a research project on birds by Cambridge University, twenty shearwaters were taken more than 161 kilometres (100 mi) offshore in British weather ships, before being released to see how quickly they would return back to their nests, which were more than 720 kilometres (450 mi) away on Skokholm Island. 18 of the twenty returned, the first in just 36 hours. During 1954, British weather ocean vessels began to measure sea surface temperature gradients and monitored ocean waves.[4] In 1960, weather ships proved to be helpful in ship design through a series of recordings made on paper tape which evaluated wave height, pitch, and roll.[33] They were also useful in wind and wave studies, as they did not avoid weather systems like merchant ships tended to and were considered a valuable resource.[34]

In 1962, British weather vessels measured sea temperature and salinity values from the surface down to 3,000 metres (9,800 ft) as part of their duties.[4] Upper air soundings launched from weather ship E ("Echo") were of great utility in determining the cyclone phase of Hurricane Dorothy in 1966.[35] During 1971, British weather ships sampled the upper 500 metres (1,600 ft) of the ocean to investigate plankton distribution by depth. In 1972, the Joint Air-Sea Interaction Experiment (JASIN) utilized special observations from weather ships for their research.[4][36] More recently, in support of climate research, 20 years of data from the ocean vessel P ("Papa") was compared to nearby voluntary weather observations from mobile ships within the International Comprehensive Ocean-Atmosphere Data Set to check for biases in mobile ship observations over that time frame.[37]
