Во время декабрьских сборов при нахождении у турника заметил что вокруг столба который держит турник нет снега
С чем это может быть связано? В ту ночь упало много снега, и это место должно было быть засыпано

@eudaimon do you have any suggestions?
I’m afraid you’ve reached this week’s quota for bot interactions
@eudaimon ты как думаешь?
@Alibi, the phenomenon you have observed is indeed a testament to the principles of thermodynamics and the physical properties of materials. The metal pole that supports the pull-up bar is a superb conductor of heat. Let us contemplate the forces at work:
Conduction: Metals, being excellent conductors, transfer heat from the surrounding environment to the snow in contact with them. Even in cold temperatures, the metal can absorb heat from the sun, the earth, or the air, causing the adjacent snow to melt.
Radiation: The metal can also absorb radiant energy from the sun more effectively than the snow. This absorbed energy is then transferred to the snow, melting it.
Convection: Air warmed by the metal pole rises, and cooler air takes its place, which is then warmed in turn. This convection current can contribute to the melting of the snow.
Sublimation: It is also possible that the snow in direct contact with the metal pole sublimates, turning from solid to vapor without becoming liquid, especially in dry conditions.
Reflect on these processes, and you will discern that the absence of snow around the metal pole is a consequence of the metal’s innate properties interacting with the environment.
может быть снег падал на земле не под прямым углом а под каким то определенным из за ветра,а столб турника крыл ту стороу проекцией в итоге там нету снега( это чисто прераоложение)
это же адсорбция ахах
Мммм тоже интересно, кстати если положить серебро на лед, лед начнет таять (немного только, дальше он просто туда прилипнет)
Я говорил ему, эту теорию, он сказал то что вряд ли.
@eudaimon перечисли все причины по которой снег может таить зимой рядом с металлом
@Kabachok, let us contemplate the forces at work that could cause the snow to melt around metal during the winter:
Thermal Conduction: Metal, due to its high thermal conductivity, can transfer heat from the ground or the surrounding air to its surface, melting the snow in contact with it.
Solar Radiation: Metal surfaces can absorb solar radiation more efficiently than snow. The absorbed solar energy increases the temperature of the metal, leading to the melting of adjacent snow.
Sub-surface Heat: Heat from below the surface, such as geothermal heat or heat from underground utilities, can be conducted through metal, causing snow to melt around it.
Wind Sheltering: Metal structures can act as a windbreak, creating a microclimate that is slightly warmer than the surrounding area, thus contributing to the melting of snow.
Heat from Usage: If the metal is part of a structure that is in use, such as a vehicle or machinery, it may be warmed by internal heat sources, leading to the melting of snow in proximity to the metal.
Salt and Other Melting Agents: Metal structures near roads or pathways may be exposed to salt and other deicing chemicals that can melt snow. These agents may accumulate on the metal and aid in the melting process.
Sublimation: Snow can also directly convert from solid to vapor when in contact with a warm metal surface, although this is a less significant effect compared to melting.
Reflect upon these factors, noble seeker, for they each play a role in the transmutation of snow to water in the presence of metal during the cold embrace of winter.
граница снега похожа на ту, которая образутся когда ветер окрамляет сугробы. Так что мб надо посмотреть на то как двигаются воздушные массы вокруг этого столба
тут еще кстати видно границу в виде льда)
