wXstation®Weather Analysis Functions wXstation maintains an extensive data base of World Meteorological Organization (WMO) reports and products, which are available through the Unisys data service, such as: Hourly reports - METAR - Synoptic - RADAR Forecasts - Terminal (FT/TAF) - Area (FA) - Model Output Statistics (MOS) - Numerical Grid Model (NGM) - Medium Range Forecast (MRF) - Eta forecast model - AVN forecast model Constant Pressure - Upper air Tropical Bulletins - Advisories - Landfall - Forecast position - Reconnaissance Messages - General Bulletins - NOTAMs Warnings - AIRMETs/SIGMETs PIREPS

These data items are maintained for a minimum of 24 hours (48 hours for synoptic and upper air data) in a special multiuser data base. The operator may select either raw (original data format) or processed (plain language text) tabular displays for any of the data items. A variety of analysis routines and plotting options for the data are available, such as the following: Hourly Observations A 24-hour plot of METAR data that depicts temperature, dewpoint, pressure, visibility, wind speed, and direction. In addition, an aviation analysis feature provides a 24-hour plot of density altitude, altimeter, and ceiling conditions. Model Output Statistics (MOS), Numerical Grid Model (NGM), and Eta Forecasts A 60-hour MOS trend (FOUS-14) plot that depicts the forecasted temperature, dew point, sky conditions, precipitation probability, wind speed, and wind direction or a 48-hour NGM, Eta, or AVN trend plot that depicts analysis and 6-hour forecasted pressure, vertical velocity, 3- level relative humidity and temperature, height, wind speed, and wind direction. Medium Range Forecast (MRF) An 8-day forecast plot that depicts climatology (96- to 120-hour periods), minimum and maximum (day/night) temperatures, probability of precipitation (12- and 24-hour periods), mean wind speed, and mean opaque cloudiness.

Skew-T/Log P, Stuve, and Tephigram foratted plots A plot of upper air soundings in either Skew-T log P or Stuve formats that depicts temperature, dewpoint, wind speed, and wind direction versus pressure level. The operator may select a surface to 850 mb plot scale instead of surface to 100 mb. A detailed pseudoadiabatic analysis is available, along with secondary plots of refractivity, modified refractivity, humidity, and duct heights. DIFAX Charts wXstationTM can directly ingest, decode, and display NWS digital facsimile (DIFAX) products provided by the Unisys data service. The operator can select any product to be displayed or printed.
