If the roll was covered with snow and ice during the night, the extra weight made it that much warmer inside. If when he woke it was freezing cold outside, he dressed a la Pullman berth, without quitting his warm blankets. If, on the other hand, the weather was warm, he could arrange his blankets in such a way as to have most of them underneath ...
Sleet and freezing rain occur by a similar process, but are different forms of precipitation. Both are most common in the winter. Sleet occurs when snowflakes melt into a raindrop in a wedge of ...
Sulfuric acid rain in the atmosphere of Venus evaporates before reaching the ground due to the high heat near the surface. [2] Similarly, virgae happen on gas giant planets such as Jupiter . [ citation needed ] In September 2008, NASA's Phoenix lander discovered a snow variety of virga falling from Martian clouds.
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.

The main forms of precipitation include drizzle, rain, Rain and snow mixed ("sleet" in Commonwealth usage), snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity ), so that the water condenses and "precipitates" or falls.
Icings – Roofs must also be designed to avoid ice dams, which result from meltwater running under the snow on the roof and freezing at the eave. Ice dams on roofs form when accumulated snow on a sloping roof melts and flows down the roof, under the insulating blanket of snow, until it reaches below freezing temperature air, typically at the ...
