Question: When does it start to snow in the city where the author of A Lord from Planet Earth works?

<P0-S0> A Lord from Planet Earth () — trilogy of science-fiction novels by Russian writer Sergey Lukyanenko. <P0-S1> While the predominant genre is science-fiction, the novels also include some elements of the fantasy genre. <P0-S2> Only available in Russian language. <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> Written in 2005, Moscow, Rough Draft by Sergey Lukyanenko is a fantasy novel of the "parallel world" genre. <P2-S1> It was followed by "Final Draft". <SEP> <P3-S0> the crack in space is a 1966 science fiction novel by american writer philip k. dick. <P3-S1> in the united kingdom, it has been published under the title of the original novella, "cantata 140", published in the july 1964 issue of" the magazine of fantasy & science fiction". <P3-S2> this original title refers to the short title in english, "sleepers awake", of j.s. <P3-S3> bach's cantata bwv 140 and the novel's 'bibs', the millions sleeping in suspended animation. <P3-S4> both are based on the short story "prominent author". <P3-S5> the common elements are the jiffi-scuttler transport device, the company, terran development, that manufactures it (and still exists to play a large role in the later works), and a brief summary of "prominent author" as an event of the past in chapter 2. the "crack in space" is a defect in jiffi-scuttler operation that allows access to the earth (in "prominent author") and to parallel earths (in the later works) at various times and locations, beyond its intended use of providing near-instant transport between specific locations on the earth in the present. <SEP> <P4-S0> neptune is not visible to the unaided eye and is the only planet in the solar system found by mathematical prediction rather than by empirical observation. <P4-S1> unexpected changes in the orbit of uranus led alexis bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. <P4-S2> neptune was subsequently observed with a telescope on 23 september 1846 by johann galle within a degree of the position predicted by urbain le verrier. <P4-S3> its largest moon, triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. <P4-S4> the planet's distance from earth gives it a very small apparent size, making it challenging to study with earth-based telescopes. <P4-S5> neptune was visited by voyager 2, when it flew by the planet on 25 august 1989. the advent of hubble space telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
