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

The wetter season lasts 2.8 months, from June 26 to September 19, with a greater than 42% chance of a given day being a wet day. The chance of a wet day peaks at 79% on August 3.

The drier season lasts 9.2 months, from September 19 to June 26. The smallest chance of a wet day is 4% on January 3.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 79% on August 3.

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. Abomsa experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 9.9 months, from January 9 to November 7, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around August 1, with an average total accumulation of 7.2 inches.

The rainless period of the year lasts for 2.1 months, from November 7 to January 9. The least rain falls around November 28, with an average total accumulation of 0.4 inches.

The earliest sunrise is at 5:57 AM on May 29, and the latest sunrise is 45 minutes later at 6:42 AM on January 27. The earliest sunset is at 5:54 PM on November 16, and the latest sunset is 51 minutes later at 6:45 PM on July 12.

Daylight saving time (DST) is not observed in Abomsa 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 Abomsa, 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, staying within 1% of 1% 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 average hourly wind speed in Abomsa experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 8.2 months, from October 2 to June 7, with average wind speeds of more than 3.0 miles per hour. The windiest day of the year is October 30, with an average hourly wind speed of 3.6 miles per hour.

The calmer time of year lasts for 3.8 months, from June 7 to October 2. The calmest day of the year is August 16, with an average hourly wind speed of 2.3 miles per hour.

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

The wind is most often from the east for 4.1 months, from March 6 to July 9 and for 1.3 months, from August 21 to September 30, with a peak percentage of 50% on May 29. The wind is most often from the west for 1.4 months, from July 9 to August 21, with a peak percentage of 39% on July 28.

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 some seasonal variation over the course of the year.

The brighter period of the year lasts for 1.6 months, from April 26 to June 14, with an average daily incident shortwave energy per square meter above 6.9 kWh. The brightest day of the year is May 25, with an average of 7.2 kWh.

The darker period of the year lasts for 1.1 months, from July 9 to August 12, with an average daily incident shortwave energy per square meter below 6.1 kWh. The darkest day of the year is July 25, with an average of 5.8 kWh.

Temperature and Dew Point

There is only a single weather station, Addis Ababa Bole International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Abomsa.

At a distance of 172 kilometers from Abomsa, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .

The weight assigned to the MERRA-2 value depends on the distance from Abomsa to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 30%, making the weight assigned to the weather station 70%.

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.
