A shower will produce rain if the temperature is above the freezing point in the cloud, or snow / ice pellets / snow pellets / hail if the temperature is below it at some point. [1] In a meteorological observation, such as the METAR, they are noted SH giving respectively SHRA, SHSN, SHPL, SHGS and SHGR. [2] [3]
A snow flurry is a light snowfall that results in little or no snow accumulation. The US National Weather Service defines snow flurries as intermittent light snow that produces no measurable precipitation (trace amounts). [1] In contrast, bursts of snowfall that do result in measurable snow accumulation are called snow showers. [2]
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 ...
Heavy rain describes rainfall with a precipitation rate above 7.6 millimetres (0.30 in) per hour, and violent rain has a rate more than 50 millimetres (2.0 in) per hour. [11] Snowfall intensity is classified in terms of visibility instead. When the visibility is over 1 kilometre (0.62 mi), snow is determined to be light.
Snow flurry, snow shower, snow storm and blizzard describe snow events of progressively greater duration and intensity. [35] A blizzard is a weather condition involving snow and has varying definitions in different parts of the world.
Precipitation, especially rain, has a dramatic effect on agriculture. All plants need at least some water to survive, therefore rain (being the most effective means of watering) is important to agriculture. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops.
Seattle's January rainfall has been about 20% of the historical average, which is 5.78 inches. Meanwhile, Portland has picked up just over 2 inches of rain, compared to a historical average of ...
Liquid droplets of rain that become supercooled while falling through a sub-freezing air mass and then freeze upon impact with any surface they encounter; the resulting glaze ice can accumulate to a thickness of several centimeters. Unlike mixed rain and snow, ice pellets, and hail, freezing rain exists entirely as a liquid until it hits a surface.
