[ 1 ] Federal Aviation Administration records say the airport had 15,983 passenger boardings (enplanements) in calendar year 2008, [ 2 ] 13,692 in 2009 and 14,686 in 2010. [ 3 ]
The LEDWI must provide a positive indication of unknown precipitation or rain before the system can transmit a report of freezing rain. If the LEDWI reports either no precipitation or snow, the system will ignore the input from the freezing rain sensor. The sensor is designed to detect and report icing from all weather conditions.
Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction; Present Weather/Precipitation Identification Sensor for identifying falling precipitation; Disdrometer for measuring drop ...
The same SNOTEL site in Nevada. The large panel in the foreground is the snow pillow. Basic SNOTEL sites have a pressure sensing snow pillow, storage precipitation gauge, and air temperature sensor. However, they can accommodate 64 channels of data and will accept analog and parallel or serial digital sensors.
According to the government's data, 2003 had the least snow cover in the U.S., with 21.2% of land blanketed by snow. The snowiest Christmas happened in 2009, with over 60% of the ground covered.
Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as a weather radar. When classified according to the rate of precipitation, rain can be divided into categories. Light rain describes rainfall which falls at a rate of between a trace and 2.5 millimetres (0.098 in) per hour. Moderate rain describes ...
Standard rain gauge. The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 10 cm (3.9 in) plastic and 20 cm (7.9 in) metal varieties. [83] The inner cylinder is filled by 2.5 cm (0.98 in) of rain, with overflow flowing into the outer cylinder.
The generic term, Winter Storm Watch, is used for hazardous winter precipitation in the form of heavy snow, freezing rain or sleet, or a combination of the precipitation types, sometimes accompanied by strong winds. The forecast accumulation criteria for each frozen precipitation type vary significantly over different county warning areas.
