A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Nusaybin varies throughout the year.

The wetter season lasts 6.7 months, from October 23 to May 13, with a greater than 11% chance of a given day being a wet day. The chance of a wet day peaks at 23% on February 14.

The drier season lasts 5.3 months, from May 13 to October 23. The smallest chance of a wet day is 0% on July 14.

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. Nusaybin experiences some seasonal variation in monthly rainfall.

The rainy period of the year lasts for 7.1 months, from October 14 to May 18, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around February 8, with an average total accumulation of 1.4 inches.

The rainless period of the year lasts for 4.9 months, from May 18 to October 14. The least rain falls around August 21, with an average total accumulation of 0.0 inches.

Daylight saving time (DST) is not observed in Nusaybin during 2017.

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.

The perceived humidity level in Nusaybin, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The predominant average hourly wind direction in Nusaybin varies throughout the year.

The wind is most often from the north for 2.6 months, from March 1 to May 21 and for 1.8 months, from October 2 to November 26, with a peak percentage of 36% on May 20. The wind is most often from the west for 4.4 months, from May 21 to October 2, with a peak percentage of 48% on August 23. The wind is most often from the east for 3.2 months, from November 26 to March 1, with a peak percentage of 40% on January 1.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.3 months, from May 15 to August 25, with an average daily incident shortwave energy per square meter above 7.4 kWh. The brightest day of the year is June 22, with an average of 8.7 kWh.

The darker period of the year lasts for 3.6 months, from November 1 to February 17, with an average daily incident shortwave energy per square meter below 3.6 kWh. The darkest day of the year is December 24, with an average of 2.3 kWh.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Nusaybin.

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

The stations contributing to this reconstruction are: Kamishli (98%, 5.9 kilometers, south) and Batman Airport (1.5%, 96 kilometers, north).

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.
