If there’s enough Saharan dust during hurricane season, it prevents tropical storms from getting started or gaining strength. This dust can be blown for thousands of kilometers and settle in places as far away as Florida and the Bahamas. The Sahara is the largest source of windblown dust to the Earth’s atmosphere. Over the final week of June and into early July, haze settled in over the tropical Atlantic. The dust has trekked as far poleward as Scandinavia, and could be swept back toward Greenland in the next 72 hours. Sahara dust plume in 1998, heading over the north-east Atlantic Ocean. Dust particles come from rocks in the Tibesti region and broken down by processes such as weathering, erosion and pulverisation. As in other parts of the world, the wind can blow strongly over deserts - whipping up dust and sand high into the sky. In addition, increased amounts of greenhouse gases in the atmosphere could heat the Sahara and weaken winds, causing less dust to enter the air. A drier desert would mean dust would increase, while a wetter desert would reduce dust. The alignment of nearby mountain ranges functions like a wind tunnel, funneling strong winds over the depression on a regular basis. The Sahara is the major source on Earth of mineral dust (60-200 million tons per year [citation needed]).Saharan dust can be lifted by convection over hot desert areas, and can thus reach very high altitudes; from there it can be transported worldwide by winds, covering distances of thousands of kilometers. One of the largest sources of dust in the Sahara is the Bodélé Depression, a dried lake-bed in northern Chad that is rich with silt and fine-grained dust. The data show that wind and weather pick up on average 182 million tons of dust each year and carry it past the western edge of the Sahara at longitude 15W. HOUSTON – It happens a few times every summer -- dust from the sands of the Sahara Desert in North Africa are carried on the wind, across the globe to Houston. The plume came from small dust particles that were picked up from the Sahara Desert in Africa and transported thousands of miles by the wind. The data show that wind and weather pick up on average 182 million tons of dust each year and carry it past the western edge of the Sahara at longitude 15W. Dust storms in the Sahara are killing kids half a continent away A new study looks at the effects of air pollution from desert dust. There is currently no apparent trend in how much dust is blown away from the Sahara each year. “When winds are especially strong, the dust can be transported several thousand miles, reaching as far as the Caribbean, Florida and the U.S. Gulf Coast,” the NOAA website says. "By using data from two satellites that take images of the same areas three hours apart, we can estimate the wind speed and calculate the size of the 'dust parcels' that are produced at … Here's a mind-blowing fact: Sand from the Saharan Desert can blow across the Atlantic and deposit itself into the Amazon rainforest.

NASA Visible Earth. usa today Sure, it's always hot in Texas in July, but this week a new ingredient from an ocean away is adding to the heat misery there: Plumes of dust from the Sahara Desert … Saharan dust is a mixture of sand and dust from the Sahara, the vast desert area that covers most of North Africa. It has been estimated that 400m to 700m tons of dust is transported from the Sahara … As in other parts of the world, the wind can blow strongly over deserts - whipping up dust and sand high into the sky.
