Question: How many tornadoes are there per year, in the state that has a Charlotte diocese, of the religious group whose archdiocese is seated in Warsaw?

full_context: Document 1: North Carolina: Severe weather occurs regularly in North Carolina. On the average, a hurricane hits the state once a decade. Destructive hurricanes that have struck the state include Hurricane Fran, Hurricane Floyd, and Hurricane Hazel, the strongest storm to make landfall in the state, as a Category 4 in 1954. Hurricane Isabel stands out as the most damaging of the 21st century. Tropical storms arrive every 3 or 4 years. In addition, many hurricanes and tropical storms graze the state. In some years, several hurricanes or tropical storms can directly strike the state or brush across the coastal areas. Only Florida and Louisiana are hit by hurricanes more often. Although many people believe that hurricanes menace only coastal areas, the rare hurricane which moves inland quickly enough can cause severe damage; for example, in 1989, Hurricane Hugo caused heavy damage in Charlotte and even as far inland as the Blue Ridge Mountains in the northwestern part of the state. On the average, North Carolina has 50 days of thunderstorm activity per year, with some storms becoming severe enough to produce hail, flash floods, and damaging winds.
Document 2: Warsaw: Warsaw's mixture of architectural styles reflects the turbulent history of the city and country. During the Second World War, Warsaw was razed to the ground by bombing raids and planned destruction. After liberation, rebuilding began as in other cities of the communist-ruled PRL. Most of the historical buildings were thoroughly reconstructed. However, some of the buildings from the 19th century that had been preserved in reasonably reconstructible form were nonetheless eradicated in the 1950s and 1960s (e.g. Leopold Kronenberg Palace). Mass residential blocks were erected, with basic design typical of Eastern bloc countries.
Document 3: Warsaw: Gothic architecture is represented in the majestic churches but also at the burgher houses and fortifications. The most significant buildings are St. John's Cathedral (14th century), the temple is a typical example of the so-called Masovian gothic style, St. Mary's Church (1411), a town house of Burbach family (14th century), Gunpowder Tower (after 1379) and the Royal Castle Curia Maior (1407–1410). The most notable examples of Renaissance architecture in the city are the house of Baryczko merchant family (1562), building called "The Negro" (early 17th century) and Salwator tenement (1632). The most interesting examples of mannerist architecture are the Royal Castle (1596–1619) and the Jesuit Church (1609–1626) at Old Town. Among the first structures of the early baroque the most important are St. Hyacinth's Church (1603–1639) and Sigismund's Column (1644).
Document 4: Warsaw: Building activity occurred in numerous noble palaces and churches during the later decades of the 17th century. One of the best examples of this architecture are Krasiński Palace (1677–1683), Wilanów Palace (1677–1696) and St. Kazimierz Church (1688–1692). The most impressive examples of rococo architecture are Czapski Palace (1712–1721), Palace of the Four Winds (1730s) and Visitationist Church (façade 1728–1761). The neoclassical architecture in Warsaw can be described by the simplicity of the geometrical forms teamed with a great inspiration from the Roman period. Some of the best examples of the neoclassical style are the Palace on the Water (rebuilt 1775–1795), Królikarnia (1782–1786), Carmelite Church (façade 1761–1783) and Evangelical Holy Trinity Church (1777–1782). The economic growth during the first years of Congress Poland caused a rapid rise architecture. The Neoclassical revival affected all aspects of architecture, the most notable are the Great Theater (1825–1833) and buildings located at Bank Square (1825–1828).
Document 5: Climate of North Carolina: There is an average of forty - five inches of rain a year (fifty in the mountains). July storms account for much of this precipitation. As much as 15% of the rainfall during the warm season in the Carolinas can be attributed to tropical cyclones. Mountains usually see some snow in the fall and winter. Moist winds from the southwest drop an average of 80 inches (2,000 mm) of precipitation on the western side of the mountains, while the northeast - facing slopes average less than half that amount.
Document 6: Peter Joseph Jugis: Peter Joseph Jugis (born March 3, 1957) is an American prelate of the Roman Catholic Church serving as the fourth and current bishop of the Roman Catholic Diocese of Charlotte. He succeeded Bishop William George Curlin as bishop of the diocese and is seated at the Cathedral of St. Patrick in Charlotte, North Carolina.
Document 7: Warsaw: The city is the seat of a Roman Catholic archdiocese (left bank of the Vistula) and diocese (right bank), and possesses various universities, most notably the Polish Academy of Sciences and the University of Warsaw, two opera houses, theatres, museums, libraries and monuments. The historic city-centre of Warsaw with its picturesque Old Town in 1980 was listed as a UNESCO World Heritage Site. Other main architectural attractions include the Castle Square with the Royal Castle and the iconic King Sigismund's Column, St. John's Cathedral, Market Square, palaces, churches and mansions all displaying a richness of colour and architectural detail. Buildings represent examples of nearly every European architectural style and historical period. Warsaw provides many examples of architecture from the gothic, renaissance, baroque and neoclassical periods, and around a quarter of the city is filled with luxurious parks and royal gardens.
Document 8: North Carolina: North Carolina averages fewer than 20 tornadoes per year, many of them produced by hurricanes or tropical storms along the coastal plain. Tornadoes from thunderstorms are a risk, especially in the eastern part of the state. The western Piedmont is often protected by the mountains, which tend to break up storms as they try to cross over; the storms will often re-form farther east. Also a weather phenomenon known as "cold air damming" often occurs in the northwestern part of the state, which can also weaken storms but can also lead to major ice events in winter.
Document 9: Roman Catholic Diocese of Charlotte: Canonically erected on November 12, 1971, by Pope Paul VI, the diocese took its territories from the neighboring Diocese of Raleigh. The Charlotte See is led by a bishop who serves as pastor of the Cathedral of Saint Patrick in Charlotte, North Carolina. Peter Joseph Jugis is the current bishop. The diocese is also home to two of the three basilicas in North Carolina, the Basilica of St. Lawrence and the Basilica of Our Lady Help of Christians.
Document 10: Warsaw: Thanks to numerous musical venues, including the Teatr Wielki, the Polish National Opera, the Chamber Opera, the National Philharmonic Hall and the National Theatre, as well as the Roma and Buffo music theatres and the Congress Hall in the Palace of Culture and Science, Warsaw hosts many events and festivals. Among the events worth particular attention are: the International Frédéric Chopin Piano Competition, the International Contemporary Music Festival Warsaw Autumn, the Jazz Jamboree, Warsaw Summer Jazz Days, the International Stanisław Moniuszko Vocal Competition, the Mozart Festival, and the Festival of Old Music.
Document 11: Climate of North Carolina: Snow in North Carolina is seen on a regular basis in the mountains. North Carolina averages 5 inches (130 mm) of snow a year. However, this also varies greatly across the state. Along the coast, most areas register less than 2 inches (51 mm) per year while the state capital, Raleigh averages 7.5 inches (190 mm). Farther west in the Piedmont - Triad, the average grows to approximately 9 inches (230 mm). The Charlotte area averages approximately 6.5 inches (170 mm). The mountains in the west act as a barrier, preventing most snowstorms from entering the Piedmont. When snow does make it past the mountains, it is usually light and is seldom on the ground for more than two or three days. However, several storms have dropped 18 inches (460 mm) or more of snow within normally warm areas. The 1993 Storm of the Century that lasted from March 11 to March 15 affected locales from Canada to Central America, and brought a significant amount of snow to North Carolina. Newfound Gap received more than 36 inches (0.91 m) of snow with drifts more than 5 feet (1.5 m), while Mount Mitchell measured over 4 feet (1.2 m) of snow with drifts to 14 feet (4.3 m). Most of the northwestern part of the state received somewhere between 2 feet (0.61 m) an 3 feet (0.91 m) of snow.
Document 12: Saint Peter and Paul Cathedral, Lutsk: The Saint Peter and Paul Cathedral and its Jesuit college are national landmarks in Lutsk. The church and college were built for the Society of Jesus of Lutsk in the 17th century. The cathedral is the main church in the Roman Catholic Diocese of Lutsk, the college part of the National university of Food Technologies.
Document 13: Tennessee: While the state is far enough from the coast to avoid any direct impact from a hurricane, the location of the state makes it likely to be impacted from the remnants of tropical cyclones which weaken over land and can cause significant rainfall, such as Tropical Storm Chris in 1982 and Hurricane Opal in 1995. The state averages around 50 days of thunderstorms per year, some of which can be severe with large hail and damaging winds. Tornadoes are possible throughout the state, with West and Middle Tennessee the most vulnerable. Occasionally, strong or violent tornadoes occur, such as the devastating April 2011 tornadoes that killed 20 people in North Georgia and Southeast Tennessee. On average, the state has 15 tornadoes per year. Tornadoes in Tennessee can be severe, and Tennessee leads the nation in the percentage of total tornadoes which have fatalities. Winter storms are an occasional problem, such as the infamous Blizzard of 1993, although ice storms are a more likely occurrence. Fog is a persistent problem in parts of the state, especially in East Tennessee.

Document 15: List of Catholic dioceses in the United States: The Roman Catholic Church has a total of 197 particular churches -- consisting of 32 territorial archdioceses, 145 territorial dioceses, the Archdiocese for the Military Services, USA (serving members of the US Armed Forces and Diplomatic Corps, and those in facilities of the Veterans Administration and their dependents), and the Personal Ordinariate of the Chair of Saint Peter (serving Catholics who were formerly Anglicans) within the Roman Rite; and two archieparchies and 16 eparchies in the Eastern Catholic Churches -- in the 50 United States and the US Virgin Islands. The pastor of any particular church other than an ordinariate must be episcopally ordained, but his title conforms to that of his jurisdiction: the pastor of an archdiocese is an archbishop, the pastor of a diocese is a bishop, the pastor of an archieparchy is an archieparch, the pastor of an eparchy is an eparch, and the pastor of an exarchate is an exarch. The pastor of an ordinariate, titled the ``ordinary ''(which is a term also used generically for the pastor of any particular church), may be either a bishop if celibate, or a presbyter (priest) if married, but he holds the same power of governance of his ordinariate that a bishop has of his diocese in either case; Pope Benedict XVI deliberately instituted this provision to permit married, former Anglican bishops who come into full communion with the Catholic Church along with many of their congregants to accede to office while respecting sensitivities in ecumenical relations with the Eastern Orthodox Churches, which also maintain a celibate episcopacy. The pastor of each particular church is, ex officio, a full member of the United States Conference of Catholic Bishops (USCCB). Auxiliary and retired bishops are also members of the Conference but have no vote.
