Understanding the Saharan Air Layer and Its Impact on North Texas
Thunderstorms have been North Texas’s primary weather phenomenon of late, but another may be on the horizon this week.
Clouds of Saharan dust, originating in North Africa, have made their way across the Atlantic Ocean and are impacting states along the Gulf of Mexico this week, with some of the biggest effects expected in Florida.
North Texas may even see some results of the dust incursion, but Monique Sellers, a meteorologist with the National Weather Service’s Fort Worth office, said she expects those impacts to be relatively minor.
What is the Saharan Air Layer?
The Saharan Air Layer, as scientists call it, forms outbreaks when large amounts of dust are kicked up from the southern edge of the desert. As it crosses the Atlantic, the air layer is often over 2 miles tall, according to a National Atmospheric and Oceanic Administration’s team that studies the phenomenon. It usually starts about a mile above the ocean’s surface.
The Saharan Air Layer is a natural phenomenon that occurs when strong winds pick up dust and sand from the Sahara Desert and carry it across the Atlantic Ocean. This can happen several times a year, but the impact of the dust on the weather and air quality in North Texas is usually minimal.
How Does the Saharan Air Layer Affect the Weather?
Plumes of dust frequently break off and travel across the ocean in the summer, the NOAA team said, but they can vary in size. The dry air and strong winds can sometimes act to suppress hurricane formation in the Atlantic.
The Saharan Air Layer can also impact the weather in North Texas, but the effects are usually limited. The dry air and strong winds can help to suppress the formation of thunderstorms, but the dust can also contribute to hazy skies and colorful sunsets.
What Can North Texas Residents Expect?
Sellers said the air mass will likely thin as it makes its way over land, limiting impacts for residents of North Texas. It will most likely be observable starting Saturday, with storm clouds keeping the dust farther south before that.
The largest observable impacts for the metro area will likely be some hazy skies and particularly colorful sunsets. No health hazards are expected.
The Texas coast may experience some reduced air quality, Sellers said, but added air quality determinations are made by the Texas Commission on Environmental Quality. The Houston office of the weather service shared a similar warning.
Should North Texas Residents Be Concerned?
Sellers encouraged North Texas residents not to worry about the dust, adding that while it may sound novel, the air layer’s migration is a relatively routine event.
In fact, the Saharan Air Layer is a natural phenomenon that has been occurring for thousands of years. While it can impact the weather and air quality, the effects are usually minimal and short-lived.
Conclusion
In conclusion, the Saharan Air Layer is a natural phenomenon that can impact the weather and air quality in North Texas. While the effects are usually minimal, it’s always a good idea to stay informed about the weather and any potential hazards. By understanding the Saharan Air Layer and its impact on North Texas, residents can be better prepared for any changes in the weather.
