MIAMI — Florida is preparing to receive a huge cloud of dust from the Sahara Desert this weekend. This phenomenon, known for its ability to travel thousands of kilometers across the Atlantic, could significantly influence the climate of the region and offer impressive sunset views.
He National Oceanic and Atmospheric Service (NOAA) He reported that these dust clouds typically form between mid-June and August. During this period, trade winds from North Africa lift sand particles, transporting them across the ocean to North America. Along the way, these dry dust particles affect several climatic variables, including decreasing humidity and lowering sea surface temperatures.
The meteorologist Amanda Holly She explained that the density of these dust clouds can partially block sunlight, preventing ocean temperatures from rising excessively. “If the dust clouds remain as dense as they are now, they literally block sunlight and prevent the waters from warming further,” the expert told ABC News, according to review Infobae.
Impact on air quality
Saharan dust, while it can create spectacular sunrise and sunset views due to light scattering, also has an adverse impact on air quality. Airborne particles can cause respiratory problems and aggravate pre-existing conditions such as asthma and other lung diseases. Additionally, they can cause skin and eye irritations if concentrations are high enough.
Florida authorities recommend vulnerable populations, such as children, the elderly and people with respiratory problems, limit their exposure to the outdoors during the arrival of the dust cloud. In addition, the use of indoor air purifiers is also suggested to mitigate the effects of suspended particles.
Formation of tropical cyclones
The presence of Saharan dust also has a significant effect on cyclonic activity. The dry air mass accompanying the dust can inhibit the formation and development of tropical storms and hurricanes, creating less favourable conditions for their organisation. This effect is particularly relevant in the context of the current hurricane season, which has been classified as very active.
“This limits the potential environment for tropical systems to coalesce and organize,” Holly said. However, if a storm does manage to break through the Saharan air layer, it could rapidly intensify and become severe.
