Sahara dust is playing a crucial role in keeping the tropics calm over the coming days, according to a recent warning from a Cuban meteorologist. This phenomenon, which occurs most frequently from late June to mid-August, involves waves of Saharan dust crossing the Atlantic and even reaching the Gulf of Mexico, specialist Raydel Ruisánchez stated on his Facebook account.
During this period, tropical disturbances are affected by this layer of dry air from the Sahara, with strong winds associated that significantly limit the formation of tropical cyclones, the meteorologist pointed out. He emphasized that currently, there is only one disturbance near the east coast of the United States, with very low chances of developing into a tropical cyclone.
"While the Saharan air layer keeps cyclonic activity in check at the moment, we must be prepared for a possible increase in tropical cyclones once these concentrations decrease in August and September," the specialist warned.
Intense Cyclone Season Forecast
Regarding the intense cyclone season forecasted, the meteorologist cited Colorado State University, which in its recent update increased its numbers to 25 named storms, 12 hurricanes, and 6 major hurricanes, including those already formed. Additionally, the university noted that there is a 67% chance that a major hurricane will impact Cuban territory, he underlined.
The Sahara dust has temporarily affected tropical activity and has contributed to cooling the Atlantic waters, especially near Africa, according to a recent report from the news portal Local 10. The dry, dust-laden air from the North African deserts typically peaks in late June and July and is an anticipated part of the seasonal cycle.
In 2023, the presence of Sahara dust was minimal, with the lowest coverage recorded in at least 20 years since satellites began measuring this variable.
Impact of Sahara Dust on Tropical Weather
Here are some frequently asked questions about the impact of Sahara dust on tropical weather, especially in light of the recent warnings from meteorologist Raydel Ruisánchez.
How does Sahara dust affect tropical cyclone formation?
Sahara dust carries dry air and strong winds that can inhibit the formation of tropical cyclones by disrupting the moisture and atmospheric conditions needed for cyclone development.
When is Sahara dust most prevalent?
Sahara dust is most prevalent from late June to mid-August, with peaks typically occurring in late June and July.
What is the forecast for the 2023 cyclone season in terms of Sahara dust impact?
In 2023, the presence of Sahara dust was minimal, with the lowest coverage recorded in at least 20 years, potentially leading to less inhibition of tropical cyclone formation.
