The term "trace" is used in two different but related contexts. The first is in weather forecasting and record-keeping of rain, snow, and other precipitation, where a trace denotes an amount of precipitation that is greater than zero, but is too small to be measured by standard units or methods of measurement.
Rain and snow mixed (American English) or sleet (Commonwealth English) is precipitation composed of a mixture of rain and partially melted snow.Unlike ice pellets, which are hard, and freezing rain, which is fluid until striking an object where it fully freezes, this precipitation is soft and translucent, but it contains some traces of ice crystals from partially fused snowflakes, also called ...
The present weather symbol depicts the current weather which normally is obstructing the visibility at the time of observation. The visibility itself is shown as a number, in statute miles in the United States and meters elsewhere, describing how far the observer can see at that time. This number is located to the left of the present weather ...
For example, snow tires which enhance traction during harsh winter driving conditions are labelled with a snowflake on the mountain symbol. [32] A stylized snowflake has been part of the emblem of the 1968 Winter Olympics , 1972 Winter Olympics , 1984 Winter Olympics , 1988 Winter Olympics , 1998 Winter Olympics and 2002 Winter Olympics .
Snow accumulation on ground and in tree branches in Germany Snow blowing across a highway in Canada Spring snow on a mountain in France. Classifications of snow describe and categorize the attributes of snow-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time.
The average temperature of −3 °C (26.6 °F) roughly coincides with the equatorward limit of frozen ground and snow cover lasting for a month or more. The second letter indicates the precipitation pattern—w indicates dry winters (driest winter month average precipitation less than one-tenth wettest summer month average precipitation).
Weather lore is the body of informal folklore related to the prediction of the weather and its greater meaning. Much like regular folklore, weather lore is passed down through speech and writing from normal people without the use of external measuring instruments. The origin of weather lore can be dated back to primeval men and their usage of ...
