Question: When does it start to snow in the death city of Feodor I of the country holding the exhibit of the Commission on modernization and technological development?

<P0-S0> the russian army withdrew and retreated past moscow. <P0-S1> napoleon entered the city, assuming its fall would end the war and alexander would negotiate peace. <P0-S2> however, on orders of the city's governor feodor rostopchin, rather than capitulation, moscow was burned. <P0-S3> after five weeks, napoleon and his army left. <P0-S4> in early november napoleon got concerned about loss of control back in france after the malet coup of 1812. his army walked through snow up to their knees and nearly 10,000 men and horses froze to death on the night of 8/9 november alone. <P0-S5> after battle of berezina napoleon succeeded to escape but had to abandon much of the remaining artillery and baggage train. <P0-S6> on 5 december, shortly before arriving in vilnius, napoleon left the army in a sledge. <SEP> <P1-S0> 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. <P1-S1> 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. <P1-S2> Yet in 2011 - 2012 it melted in the middle of April. <SEP> <P2-S0> June 17–19, 2010During Petersburg Economic Forum, President of the Russian Federation D.A. <P2-S1> Medvedev visited the exhibit of the Commission on modernization and technological development of the economy of Russia, where he watched the demonstration of Corporation’s developments in the field of 3D TV, namely, the first Russian 3D channel – 3DV. <SEP> <P3-S0> the best - known 'first world expo' was held in the crystal palace in hyde park, london, united kingdom, in 1851, under the title ``great exhibition of the works of industry of all nations ''. <P3-S1> the great exhibition, as it is often called, was an idea of prince albert, queen victoria's husband, and is usually considered to be the first international exhibition of manufactured products. <P3-S2> it influenced the development of several aspects of society, including art - and - design education, international trade and relations, and tourism. <P3-S3> these events have resulted in a remarkable form of prince albert's life history, one that continues to be reflected in london architecture in a number of ways, including in the albert memorial later erected to the prince. <P3-S4> this expo was the most obvious precedent for the many international exhibitions, later called world's fairs, that have continued to be held to the present time. <SEP> <P4-S0> As soon as the Truce of Plussa expired early in 1590, a large Russian army led by Godunov and his sickly brother-in-law, Fyodor I of Russia, marched from Moscow towards Novgorod. <P4-S1> On 18 January they crossed the Narva River and laid siege to the Swedish castle of Narva, commanded by Arvid Stålarm. <P4-S2> Another important fortress, Jama (Jamburg), fell to Russian forces within two weeks. <P4-S3> Simultaneously, the Russians ravaged Estonia as far as Reval (Tallinn) and Finland as far as Helsingfors (Helsinki).
