does it have to be 0 degrees snow UNANSWERABLE how is snow formed ? It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. how is it measured ? Among the measurements of the properties of snowpacks that the "International Classification for Seasonal Snow on the Ground" includes are: snow height, snow water equivalent, snow strength, and extent of snow cover. is it found outside earth ? Extraterrestrial "snow" includes water-based precipitation, but also precipitation of other compounds prevalent on other planets and moons in the Solar System how is it used in sports ? Common examples include cross-country skiing, Alpine skiing, snowboarding, snowshoeing, and snowmobiling. how does it effect agriculture ? It can be beneficial to agriculture by serving as a thermal insulator, conserving the heat of the Earth and protecting crops from subfreezing weather. how does it effect utility lines ? In areas with trees, utility distribution lines on poles are less susceptible to snow loads than they are subject to damage from trees falling on them, felled by heavy, wet snow is it used in warfare ? Snow affects warfare conducted in winter, alpine environments or at high latitudes. how does it effect lakes and oceans ? Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water, warming the lower layer of air which picks up water vapor from the lake, rises up through the colder air above, freezes and is deposited on the leeward (downwind) shores what are water vapors ? It is the gaseous phase of water. how is it calculated ? Water vapor and dry air density calculations at 0 °C what is its impact on air density ? Water vapor is lighter or less dense than dry air. is it present in the earth atmosphere ? It is the "working medium" of the atmospheric thermodynamic engine which transforms heat energy from sun irradiation into mechanical energy in the form of winds who discovered it ? UNANSWERABLE

Water vapor [SEP] Radar and satellite imaging
Because water molecules absorb microwaves and other radio wave frequencies, water in the atmosphere attenuates radar signals. In addition, atmospheric water will reflect and refract signals to an extent that depends on whether it is vapor, liquid or solid. Generally, radar signals lose strength progressively the farther they travel through the troposphere. Different frequencies attenuate at different rates, such that some components of air are opaque to some frequencies and transparent to others. Radio waves used for broadcasting and other communication experience the same effect. Water vapor reflects radar to a lesser extent than do water's other two phases. In the form of drops and ice crystals, water acts as a prism, which it does not do as an individual molecule; however, the existence of water vapor in the atmosphere causes the atmosphere to act as a giant prism.
