Western Air Command was the part of the Royal Canadian Air Force's Home War Establishment responsible for air operations on the Pacific coast of Canada during the Second World War.  When Canada declared war against Germany in September 1939 the command consisted of only five squadrons.  Four of them equipped with obsolete aircraft including a bomber squadron with aircraft from the Great War and there were no fighter aircraft at all for its only fighter squadron (113 Fighter Squadron was thus disbanded).  With the Japanese threat after Pearl Harbor it grew rapidly and played a critical role in fighter and anti-submarine operations in Canadian and American waters during the Aleutian Islands Campaign.  It was there that Squadron Leader K.A. Boomer of No. 111 Squadron shot down a Rufe fighter, the RCAF's only kill in the Pacific Theatre.  On 7 July 1942 a Bristol Bolingbroke pressed home an attack on the Japanese Submarine Ro 32 the pilot F/Sgt.  P.M.G. Thomas of No. 115 Squadron RCAF then led American Destroyers to sink the damaged submarine.  By January 1943 Western Air Command had expanded to include many bomber, fighter and operational units under its control.  By the end of the war the command would involve some twenty squadrons when the last units to join were added in 1943.  These were the 163 Army Cooperation Squadron in March flying Bristol Bolingbrokes and Hawker Hurricanes, in May the 160 Bomber-Reconnaissance Squadron was added flying Cansos from Sea Island BC (before moving to Yarmouth NS in July) and the 166 Communication Squadron formed in September flying various types.  In addition to the new squadrons, new aircraft types came on line replacing the command's remaining Supermarine Stranraers and Blackburn Sharks with Canso's and the Bolingbrokes and Beauforts with the Lockheed Ventura.  Countless training missions and operational patrols bolstered the air activity over the coastal areas but there was not much action until RCAF Western Command was on the look out for General Kusaba's Fire Balloons that the Japanese called the Fūsen Bakudan Campaign.  In February and March 1945, P-40 fighter pilots from 133 Squadron, Royal Canadian Air Force operating out of RCAF Patricia Bay (Victoria, British Columbia), intercepted and destroyed two fire balloons, On 21 February, Pilot Officer E. E. Maxwell While shot down a balloon, which landed on Sumas Mountain, in Washington State.  On 10 March, Pilot Officer J. O. Patten destroyed a balloon near Saltspring Island, British Columbia.  During another interception a Canso forced down a fire balloon which was examined at the army headquarters.  Patrol activity was joined by the Operational Training Schools (OTS) operated by Number 4 Training Command of the BCATP.  They were the No. 3 OTS flying the Canso and Catalina and No. 32 OTS with Ansons, Beauforts and Swordfish at Patricia Bay.  In April, 1944 the No. 5 OTS Heavy Conversion unit stood up at Boundary Bay when 16 B-24 Liberators arrived fresh from American factories.  By the end of September 1944 RCAF 5 O.T.U. had grown to sizeable force of some 87 aircraft including 38 B-24 Liberators, 35 B-25 Mitchells, 5 Bolingbrokes, 8 P-40 Kittyhawks and a single Norseman.  With the end of the war in Europe these aircraft were joined by a number of Victory Aircraft Lancaster X bombers which were to be used to train the British Commonwealth's Very Long Range Bomber Tiger Force that would soon be sent to bomb the Japanese mainland from Okinawa.  With the unconditional surrender of Japan the RCAF's Tiger Force bomber squadrons were disbanded before they flew overseas and the total draw down of the Western Air Command was suddenly undertaken.  Within several months almost all the flying squadrons would be completely stood down. Alexandre de Gusmão (Santos, 17 July 1695 – Lisbon, 9 May 1753) was a diplomat born in the Portuguese colony of Brazil.  He is regarded as one of the best diplomats of his time, chiefly for his role in negotiating the Treaty of Madrid in 1750 (revoked in 1761), when Portugal and Spain were attempting to delimit their territorial possessions in South America and Asia.  Born in the city of Santos, he may be considered one of the precursors of the application of the principles of Illuminism to international relations, adopting the principle of "uti possidetis", according to which each state has the right to the land that it actually occupies, as well as the idea of "natural boundaries", which suggests the use of prominent geographical accidents – such as rivers and mountain ranges – to set the limits between states.  He graduated in Law and was the representative of Portugal to various states, among which Rome, where he came to be invited to join Pope Innocent XIII's court.  He was also a brother of Bartolomeu de Gusmão, a priest and naturalist recalled for his early work on lighter-than-air airship design (balloons).

ERA-40 is an ECMWF re-analysis of the global atmosphere and surface conditions for 45-years, over the period from September 1957 through August 2002 by ECMWF.  Many sources of the meteorological observations were used, including radiosondes, balloons, aircraft, buoyes, satellites, scatterometers.  This data was run through the ECMWF computer model at a 125 km resolution.  As the ECMWF's computer model is one of the more highly regarded in the field of forecasting, many scientists take its reanalysis to have similar merit.  The data is stored in GRIB format.  The reanalysis was done in an effort to improve the accuracy of historical weather maps and aid in a more detailed analysis of various weather systems through a period that was severely lacking in computerized data.  With the data from reanalyses such as this, many of the more modern computerized tools for analyzing storm systems can be utilized, at least in part, because of this access to a computerized simulation of the atmospheric state.

Skyhook balloons were high-altitude balloons developed by Otto C. Winzen (1917–79) and General Mills, Inc.  They were used by the United States Navy Office of Naval Research (ONR) in the late 1940s and 1950s for atmospheric research, especially for constant-level meteorological observations at very high altitudes.  Instruments like the Cherenkov detector were first used on Skyhook balloons.
