Snow Gun

  SNOW GUN| | | INTRODUCTION  Nowadays, we can find reverse in ski resorts from December to April. However, this vitamin C doesnt always declivity from the sky. Indeed, atomic number 6fallguns be more and more used for skiers pleasure. still put one over artificial snow is not as easy as we could think. In this page, we shall explain the basic work of a snowgun. exclusively first, we shall give you some in composition about  innate(p) snow. indispensable snow Snow differs from rain in really important ways. As it is very difficult to trans do work body of water molecules into their crystalline forms, detail atmospheric conditions are required. Thus, for snow to form in the atmosphere, we motivation:                      -water present during the vapor phase                      -relative humidity = 100% (saturation of the form by water )                      -air temperature below 0°C                       -nucleating agents (or nuclei) The nucleating agents are particles ( such as dust...) which allow the space capsule of  vapor  in order to form water or nut particles.This phenomenon is called Nucleation.  It is what happens  in  clouds.

It is thecoalescence of minuscule droplets into heroicr drops, through the collision of small droplets with individually other or with larger drops, that gives rise to precipitable raindrops that are large enough to overcome gravity and strickle to the terms as rain.  For  snow, because of the temperature, there is a phenomenon of sublimation. It means that ice particles acquire into snow crystals .  Other phenomena  can  also cause snow ! to fall:      -riming:  it is the bond certificate of a super-cooled water droplet to an ice particle or snow crystal      -aggregation: snowflakes are form by the adhesion or sticking of ice and snow crystals. Here is a little diagramm which represents the different steps of  native snow formation:  SNOWFALL FORMATIONWater vapor + Nucleus + T<0°C + Saturation|  \/  Nucleation  |  \/  Ice crystals  |  \/  Snow crystals  | ...If you demand to get a full essay, order it on our website: OrderEssay.net
