True or false It must be 32 degrees F or colder to snow?

The Answer Is TRUE





Hears Why.


Most precipitation that reaches the ground actually begins as snow high in the atmosphere. These snow flakes develop somewhere above the freezing level where the air temperature is less than 32 F (the dashed blue line), and begin to fall toward the earth as snow. If ground temperature is above 32 F, the freezing level must be located somewhere above the ground. The falling snow passes through the freezing level into the warmer air, where it melts and changes to rain before reaching the ground.

Did you ever wonder how can it snow at above freezing temperatures? Well, the naive explanation is that it simply takes time for the snowflakes to melt once they penetrate above freezing air, as they descend downwards to the ground. This, of course, is the reason why hail can fall in warm weather. Simply, hail stones fall fast, too fast to let the warm air melt the hail. This is not the main explanation, however, for why it can snow when it is above freezing.

In a situation where the temperature is above freezing and snow begins to fall, the 2m above ground temperature will often quickly drop to 32 F and remain at this temperature. As snow falls into a layer of above freezing air, the snow can cool the air in three ways: sublimation, melting, and evaporation. The most significant cooling occurs from the evaporation process as snow falls through above freezing air. Melting also cools the air somewhat. The evaporation process absorbs about 7.5 times as much latent heat as the melting process. Therefore, snow falling through dry air will cool the air much more quickly than when snow falls through saturated air. The following essay explains the rate snowflakes melts as they falls in detail:

skTrue or false It must be 32 degrees F or colder to snow?
False. It can be warmer than 32F to snow, but only below 32F will the snow stick on the ground.True or false It must be 32 degrees F or colder to snow?
Super False! It has snowed in LA and it wasn't that cold.
True


32 degrees is the temperature something has to be to freeze. All snow is is frozen water. Yes, to make snow the temperature must be below freezing.


If you have a snow machine that makes fake snow, then it can be any temperature you want.
False, it can be 40 degrees low at ground level and it can still be as low as -10 high in the air where snow forms first, and once it forms it can fall to earth even with the temp on the ground level being 40 but with the temp being 40 it will melt when it lands on something.
It can snow above 32 degrees but it has to be 32 degrees or below for it to stick to the ground.
if the weather defrost's the snow


then it is too warm for the snow,,,,
False. It an snow at 34 degrees, just not make it to the ground (it will melt when it touches the ground.)
false
false, the ground has to be 32 F or lower for snow to stick. it can be up to 34-35 F to snow.... i think
False
False. It only has to be 32 degrees F or colder in the cloud where snowflakes are formed.





A snowflake forms as water vapor freezes directly into an ice crystal without passing through the liquid state. As the ice crystal grows, it bonds with other ice crystals and takes on the familiar six-sided shape of a snowflake. When the snowflake becomes heavy enough, it falls to the ground.





If the snowflake is large enough, it may pass successfully through slightly warmer air without fully melting. This would account for snow-falls at certain temperatures just above 32 degree F.
