Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Ansted experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year in Ansted. The most rain falls during the 31 days centered around May 18, with an average total accumulation of 3.9 inches.

The least rain falls around January 22, with an average total accumulation of 2.0 inches.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Ansted experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 3.8 months, from November 28 to March 23, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 11, with an average total liquid-equivalent accumulation of 0.4 inches.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

Ansted experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.4 months, from June 3 to September 16, during which time the comfort level is muggy, oppressive, or miserable at least 14% of the time. The muggiest day of the year is July 24, with muggy conditions 54% of the time.

The least muggy day of the year is November 29, when muggy conditions are essentially unheard of.

Temperature and Dew Point

There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Ansted.

For each station, the records are corrected for the elevation difference between that station and Ansted according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Ansted is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Ansted and a given station.

The stations contributing to this reconstruction are: Raleigh County Memorial Airport (37%, 39 kilometers, south); Yeager Airport (32%, 51 kilometers, northwest); Greenbrier Valley Airport (21%, 68 kilometers, southeast); and Upshur County Regional Airport (10%, 120 kilometers, northeast).

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
