Humidity

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.

Gainesboro experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 4.2 months, from May 19 to September 25, during which time the comfort level is muggy, oppressive, or miserable at least 21% of the time. The muggiest day of the year is July 25, with muggy conditions 81% of the time.

The least muggy day of the year is January 19, when muggy conditions are essentially unheard of.

Data Sources

This report illustrates the typical weather in Gainesboro, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

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

For each station, the records are corrected for the elevation difference between that station and Gainesboro 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 Gainesboro is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Gainesboro and a given station.

The stations contributing to this reconstruction are: Crossville Memorial Airport (28%, 69 kilometers, southeast); Glasgow Municipal Airport (27%, 80 kilometers, north); Smyrna Airport (24%, 86 kilometers, southwest); and Wayne County Airport (22%, 91 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.
