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?

<P0-S0> the united states averaged 1,274 tornadoes per year in the last decade while canada reports nearly 100 annually (largely in the southern regions). <P0-S1> however, the uk has most tornadoes per area per year, 0.14 per 1000 km2, although these tornadoes are generally weak, and many other european countries have a similar number of tornadoes per area. <SEP> <P1-S0> 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. <P1-S1> tornadoes are possible throughout the state, with west and middle tennessee the most vulnerable. <P1-S2> occasionally, strong or violent tornadoes occur, such as the devastating april 2011 tornadoes that killed 20 people in north georgia and southeast tennessee. <P1-S3> on average, the state has 15 tornadoes per year. <P1-S4> tornadoes in tennessee can be severe, and tennessee leads the nation in the percentage of total tornadoes which have fatalities. <P1-S5> winter storms are an occasional problem, such as the infamous blizzard of 1993, although ice storms are a more likely occurrence. <P1-S6> fog is a persistent problem in parts of the state, especially in east tennessee. <SEP> <P2-S0> 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. <P2-S1> The historic city-centre of Warsaw with its picturesque Old Town in 1980 was listed as a UNESCO World Heritage Site. <P2-S2> 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. <P2-S3> Buildings represent examples of nearly every European architectural style and historical period. <P2-S4> 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. <SEP> <P3-S0> North Carolina averages fewer than 20 tornadoes per year, many of them produced by hurricanes or tropical storms along the coastal plain. <P3-S1> Tornadoes from thunderstorms are a risk, especially in the eastern part of the state. <P3-S2> 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. <P3-S3> 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. <SEP> <P4-S0> Canonically erected on November 12, 1971, by Pope Paul VI, the diocese took its territories from the neighboring Diocese of Raleigh. <P4-S1> The Charlotte See is led by a bishop who serves as pastor of the Cathedral of Saint Patrick in Charlotte, North Carolina. <P4-S2> Peter Joseph Jugis is the current bishop. <P4-S3> 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.
