DESCRIPTION
The moisture variable calculation program derives various moisture variables given three of the following four variables: temp,dewpoint,pressure,height. If the station pressure is not known, it is determined from a standard atmosphere reduction using height. If any of the four variables temp,dewpoint,pressure,height are not specified on the command line, the user is prompted for the appropriate information. The resulting information displayed includes wetbulb temperature, vapor pressure, saturation vapor pressure, relative humidity, specific humidity, mixing ratio, saturation mixing ratio and equivalent potential temperature.
Results Temperature = 30.00 C Dewpoint = 20.00 C Station pressure = 1000.00 mb Wet bulb temperature = 22.87 C Vapor pressure = 23.36 mb Saturation vapor pressure = 42.40 mb Relative humidity = 55.08 percent Specific humidity = 14.53 grams H20 /kg air Mixing ratio = 14.88 grams H2O /kg dry air Saturation mixing ratio = 27.54 grams H2O /kg dry air Equivalent potential temperature = 347.25 K
NOTE: Fahrenheit temperatures may be entered at the temperature and dewpoint prompts by adding 1000 to the temperature to be entered.
