A snow gauge. A snow gauge is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of solid precipitation (as opposed to liquid precipitation, which is measured by a rain gauge) over a set period of time. [citation needed]
The radar reflectivity factor (Z) of precipitation is dependent on the number (N 0) and size (D) of reflectors (hydrometeors), which includes rain, snow, graupel, and hail. Very sensitive radars can also measure the reflectivity of cloud drops and ice. For an exponential distribution of reflectors, Z is expressed by: [2]
Solid precipitation A snow gauge is usually used to measure the amount of solid precipitation. Snowfall is usually measured in centimeters by letting snow fall into a container and then measure the height. The snow can then optionally be melted to obtain a water equivalent measurement in millimeters like for liquid precipitation. The ...
According to the National Oceanic and Atmospheric Administration, 1 inch of rain equals about 13 inches of snow, although the ratio can vary. By this measure, it would have snowed around 6 inches ...
Most modern rain gauges generally measure the precipitation in millimetres in height collected during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch. [16] Rain gauge amounts are read either manually or by automatic weather station ...
The snow melts into rain then refreezes just as it hits the cold ground. Since the rain is not freezing until it reaches the surface, it still falls like regular rain and therefore looks and feels ...
Rainfall in these regions averages between 300 and 600 millimeters (11.8 and 23.6 in) per year, with lower amounts across Baja California Norte. Average rainfall totals are between 600 and 1,000 millimeters (23.6 and 39.4 in) in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara.
The U.S. record is 12 inches in a single hour. That happened in a lake-effect snow band east of Lake Ontario in Copenhagen, New York, on Dec. 2, 1966, according to a list of record snowfall rates ...
