Question: When does it start to snow in the city where Wilhelm Florin died?

full_context: Document 1: Ulbricht Group: The Ulbricht Group was a group of exiled members of the Communist Party of Germany ("Kommunistische Partei Deutschlands", or KPD), led by Walter Ulbricht, who flew from the Soviet Union back to Germany on April 30, 1945. Composed of functionaries from the KPD and ten anti-fascist prisoners of war, their job was to seek out anti-fascist individuals and prepare the groundwork for the re-establishment of communist organizations and unions in postwar Berlin. There were two additional regional groups, the Ackermann Group in Saxony and the Sobottka Group in Mecklenburg. Many of the group's members later became high-level officials in the government of the German Democratic Republic (GDR).
Document 2: Boston: Boston's coastal location on the North Atlantic moderates its temperature, but makes the city very prone to Nor'easter weather systems that can produce much snow and rain. The city averages 43.8 inches (1,110 mm) of precipitation a year, with 43.8 inches (111 cm) of snowfall per season. Snowfall increases dramatically as one goes inland away from the city (especially north and west of the city)—away from the moderating influence of the ocean. Most snowfall occurs from December through March, as most years see no measurable snow in April and November, and snow is rare in May and October. There is also high year-to-year variability in snowfall; for instance, the winter of 2011–12 saw only 9.3 in (23.6 cm) of accumulating snow, but the previous winter, the corresponding figure was 81.0 in (2.06 m).[d]
Document 3: Winter: Meteorological Reckoning is the method of measuring the winter season used by meteorologists based on ``sensible weather patterns ''for record keeping purposes, so the start of meteorological winter varies with latitude. Winter is often defined by meteorologists to be the three calendar months with the lowest average temperatures. This corresponds to the months of December, January and February in the Northern Hemisphere, and June, July and August in the Southern Hemisphere. The coldest average temperatures of the season are typically experienced in January or February in the Northern Hemisphere and in June, July or August in the Southern Hemisphere. Nighttime predominates in the winter season, and in some regions winter has the highest rate of precipitation as well as prolonged dampness because of permanent snow cover or high precipitation rates coupled with low temperatures, precluding evaporation. Blizzards often develop and cause many transportation delays. Diamond dust, also known as ice needles or ice crystals, forms at temperatures approaching − 40 ° F (− 40 ° C) due to air with slightly higher moisture from aloft mixing with colder, surface based air. They are made of simple ice crystals that are hexagonal in shape. The Swedish meteorological institute (SMHI) define winter as when the daily mean temperatures go below 0 ° C (32 ° F) for five consecutive days. According to the SMHI, winter in Scandinavia is more pronounced when Atlantic low -- pressure systems take more southerly and northerly routes, leaving the path open for high -- pressure systems to come in and cold temperatures to occur. As a result, the coldest January on record in 1987 was also the sunniest in Stockholm.
Document 4: Communism in Korea: Alexandra Kim, a Korean who lived in Russia, is sometimes credited as the first Korean communist. She had joined the Bolsheviks in 1916. In 1917, Vladimir Lenin sent her to Siberia to mobilize Koreans there against the counter-revolutionary forces and the Allied Expeditionary Forces. In Khabarovsk Kim was in charge of external affairs at the Far - Eastern Department of the Party. There she met with Yi Dong - Wi, Kim Rip and other Korean independence fighters. Together they founded the Korean People's Socialist Party, the first Korean communist party on June 28, 1918.
Document 5: Molotov–Ribbentrop Pact: The Communist Party of Germany featured similar attitudes. In Die Welt, a communist newspaper published in Stockholm[e] the exiled communist leader Walter Ulbricht opposed the allies (Britain representing "the most reactionary force in the world") and argued: "The German government declared itself ready for friendly relations with the Soviet Union, whereas the English–French war bloc desires a war against the socialist Soviet Union. The Soviet people and the working people of Germany have an interest in preventing the English war plan."
Document 6: Cologne Communist Trial: The Cologne Communist Trial took place in 1852 in Cologne, Germany, and was conducted by the Prussian government against eleven members of the Communist League who were suspected of having participated in the 1848 uprising. The trial lasted from October 4 to November 12, and when it was over the Communist League dissolved itself. Seven of the eleven were sentenced to prison terms of up to six years.
Document 7: Paris: Spring and autumn have, on average, mild days and fresh nights but are changing and unstable. Surprisingly warm or cool weather occurs frequently in both seasons. In winter, sunshine is scarce; days are cold but generally above freezing with temperatures around 7 °C (45 °F). Light night frosts are however quite common, but the temperature will dip below −5 °C (23 °F) for only a few days a year. Snow falls every year, but rarely stays on the ground. The city sometimes sees light snow or flurries with or without accumulation.
Document 8: Richmond, Virginia: Precipitation is rather uniformly distributed throughout the year. However, dry periods lasting several weeks do occur, especially in autumn when long periods of pleasant, mild weather are most common. There is considerable variability in total monthly amounts from year to year so that no one month can be depended upon to be normal. Snow has been recorded during seven of the twelve months. Falls of 3 inches (7.6 cm) or more within 24 hours occur an average once per year. Annual snowfall, however, is usually light, averaging 10.5 inches (27 cm) per season. Snow typically remains on the ground only one or two days at a time, but remained for 16 days in 2010 (January 30 to February 14). Ice storms (freezing rain or glaze) are not uncommon, but they are seldom severe enough to do any considerable damage.
Document 9: Willi Lehmann: Willi (Willy) Lehmann (15 March 1884, in Leipzig – 13 December 1942, in Berlin) was a police official and Soviet agent in Nazi Germany.
Document 10: Philadelphia: Under the Köppen climate classification, Philadelphia falls in the northern periphery of the humid subtropical climate zone (Köppen Cfa). Summers are typically hot and muggy, fall and spring are generally mild, and winter is cold. Snowfall is highly variable, with some winters bringing only light snow and others bringing several major snowstorms, with the normal seasonal snowfall standing at 22.4 in (57 cm); snow in November or April is rare, and a sustained snow cover is rare. Precipitation is generally spread throughout the year, with eight to twelve wet days per month, at an average annual rate of 41.5 inches (1,050 mm), but historically ranging from 29.31 in (744 mm) in 1922 to 64.33 in (1,634 mm) in 2011. The most rain recorded in one day occurred on July 28, 2013, when 8.02 in (204 mm) fell at Philadelphia International Airport.
Document 11: Paul Merker: Paul Merker (born 1 February 1894: died Eichwalde 13 May 1969) was an activist member of Germany's Communist Party (KPD / "Kommunistische Partei Deutschlands") who later became a politician and a top official of East Germany's ruling SED (Socialist Unity Party of Germany/"Sozialistische Einheitspartei Deutschlands").
Document 12: Seattle: Autumn, winter, and early spring are frequently characterized by rain. Winters are cool and wet with December, the coolest month, averaging 40.6 °F (4.8 °C), with 28 annual days with lows that reach the freezing mark, and 2.0 days where the temperature stays at or below freezing all day; the temperature rarely lowers to 20 °F (−7 °C). Summers are sunny, dry and warm, with August, the warmest month, averaging 66.1 °F (18.9 °C), and with temperatures reaching 90 °F (32 °C) on 3.1 days per year, although 2011 is the most recent year to not reach 90 °F. The hottest officially recorded temperature was 103 °F (39 °C) on July 29, 2009; the coldest recorded temperature was 0 °F (−18 °C) on January 31, 1950; the record cold daily maximum is 16 °F (−9 °C) on January 14, 1950, while, conversely, the record warm daily minimum is 71 °F (22 °C) the day the official record high was set. The average window for freezing temperatures is November 16 thru March 10, allowing a growing season of 250 days.
Document 13: Detroit: Precipitation is moderate and somewhat evenly distributed throughout the year, although the warmer months such as May and June average more, averaging 33.5 inches (850 mm) annually, but historically ranging from 20.49 in (520 mm) in 1963 to 47.70 in (1,212 mm) in 2011. Snowfall, which typically falls in measurable amounts between November 15 through April 4 (occasionally in October and very rarely in May), averages 42.5 inches (108 cm) per season, although historically ranging from 11.5 in (29 cm) in 1881−82 to 94.9 in (241 cm) in 2013−14. A thick snowpack is not often seen, with an average of only 27.5 days with 3 in (7.6 cm) or more of snow cover. Thunderstorms are frequent in the Detroit area. These usually occur during spring and summer.
Document 14: Climate of Moscow: Snow cover (averaging 3 -- 5 months per year) is formed at the beginning of November and melts in beginning of April, but in recent years snow cover has lasted shorter than usual. For example, in the winter of 2006 -- 2007 the snow cover did n't form until the end of January, and melted at the beginning of March; in 2007 -- 2008, the snow cover melted at the end of February, and in the 2008 -- 2009 winter, snow cover did n't form until the end of December, which is one month later than usual. Yet in 2011 - 2012 it melted in the middle of April.
