Task: Question Answering
Input (English): Context_1 : Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia. Context_2 : "Do Re Mi" is a folksong by American songwriter Woody Guthrie. The song deals with the experiences and reception of Dust Bowl migrants when they arrive in California. It is known for having two guitar parts, both recorded by Guthrie. Context_3 : The Dust Bowl, also known as the Dirty Thirties, was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent wind erosion (the Aeolian processes) caused the phenomenon. The drought came in three waves, 1934, 1936, and 1939–1940, but some regions of the high plains experienced drought conditions for as many as eight years. With insufficient understanding of the ecology of the plains, farmers had conducted extensive deep plowing of the virgin topsoil of the Great Plains during the previous decade; this had displaced the native, deep-rooted grasses that normally trapped soil and moisture even during periods of drought and high winds. The rapid mechanization of farm equipment, especially small gasoline tractors, and widespread use of the combine harvester contributed to farmers' decisions to convert arid grassland (much of which received no more than 10 inches (250 mm) of precipitation per year) to cultivated cropland. Context_4 : Joseph G. Galway (December 3, 1922 – June 29, 1998), was an American meteorologist pioneering in the fields of severe convective storm forecasting and research. He was one of the first forecasters for the Severe Local Storms Unit (SELS) and the National Severe Storms Forecast Center (NSSFC), and developed synoptic (as well as mesoscale) predictors associated with severe thunderstorms and tornadoes such as the jet streak and lifted index. Context_5 : The 2013–2014 United Kingdom winter floods saw areas of the United Kingdom inundated following severe storms. The south of England saw heavy rainfalls associated with these storms which caused widespread flooding, power cuts and major disruptions to transport. Economically the worst affected areas were Somerset, Devon, Dorset and Cornwall in the south west and the Thames Valley in the south east. The Met Office reported the storms were responsible for the wettest December to January period since 1876. The flood phenomena ranged from coastal flooding, pluvial flooding, fluvial flooding to groundwater flooding. The flooding resulted in the inundation of the majority of the Somerset Levels and saw the main railway line to Cornwall and West Devon at Dawlish severed for several weeks. Context_6 : A swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air and so they are often referred to as surface gravity waves. These series of surface gravity waves are not generated by the immediate local wind, instead by distant weather systems, where wind blows for a duration of time over a fetch of water. This is the primary definition of a swell as opposed to a locally generated wind wave, which is still under the influence of the mechanisms that created it e.g. wind blowing over a puddle. More generally, a swell consists of wind-generated waves that are not—or are hardly—affected by the local wind at that time. Swell waves often have a long wavelength but this varies due to the size, strength and duration of the weather system responsible for the swell and the size of the water body e.g. wavelengths are rarely more than 150 m in the Mediterranean . Swell wavelength, also, varies from event to event. Occasionally, swells which are longer than 700 m occur as a result of the most severe storms. Swells have a narrower range of frequencies and directions than locally generated wind waves, because swell waves have dispersed from their generation area, have dissipated and therefore lost an amount of randomness, taking on a more defined shape and direction. Swell direction is the direction from which the swell is coming. It is measured in degrees (as on a compass), and often referred to in general directions, such as a NNW or SW swell. Context_7 : The 2010 Victorian storms were a series of storms that passed through much of the Australian state of Victoria on 6 March and 7 March 2010. One of the most severe storms passed directly over Greater Melbourne, bringing lightning, flash flooding, very large hail and strong winds to the state's capital. It was described as a "mini-cyclone". Context_8 : Roger Edwards is an American meteorologist and expert on severe convective storms (thunderstorms). He is the co-founder and editor-in-chief of the "Electronic Journal of Severe Storms Meteorology" ("EJSSM"). Context_9 : The backshore area of a beach extends from the limit of high water foam lines to dunes or extreme inland limit of the beach. It is only affected by waves during exceptional high tides or severe storms. Context_10 : The European Severe Storms Laboratory (ESSL) started as an informal network of European scientists with the goal to advance research on severe convective storms and extreme weather events on a European level and can be seen as the European equivalent to the National Severe Storms Laboratory. Severe weather includes extreme local meteorological events like tornados, heavy precipitation events and avalanches. fact_1 :  The song deals with the experiences and reception of Dust Bowl migrants when they arrive in California. fact_2 :  The drought came in three waves, 1934, 1936, and 1939–1940, but some regions of the high plains experienced drought conditions for as many as eight years. Question: Woody Wuthrie wrote the song "Do Re Mi" which was about migrants and their experiences when they arrive in California and are greeted with severe storms that came in waves in what years?
