The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar.It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

The Snow Day Calculator asks users to input their location, how many snow days they've had this school year and what type of school they attend. Snow Day Calculator predicts if schools will close ...
Environment Canada reports a chance of precipitation (COP) that is defined as "The chance that measurable precipitation (0.2 mm of rain or 0.2 cm of snow) will fall on any random point of the forecast region during the forecast period." [7] The values are rounded to 10% increments, but are never rounded to 50%. [8]
This will allow for mainly rain to spread across much of the mid-Atlantic region. But farther north, the cooler air seeping southward from Canada will result in areas of snow as this midweek storm ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
A series of winter storms are expected to bring rain, ice and snow to much of the Midwest and East Coast this week. According to AccuWeather, a storm emerging into the southern Plains is forecast ...
The National Snow and Ice Data Center (NSIDC) uses the reflectance of visible and infrared radiation to calculate a normalized difference snow index, which is a ratio of radiation parameters that can distinguish between clouds and snow.
A storm traveling from the northern Plains to the Midwest and Northeast into midweek will spread a swath of accumulating snow in some areas and rain in others, AccuWeather meteorologists say. The ...
