While a plume of Saharan dust is adding a haze to our sky this week, it also adds a dry layer of air to the atmosphere when filtering across the Atlantic. We talk about how that impacts tropical development in today's Whatever the Weather blog post:
While Saharan dust often adds a haze to the sky, can affect air quality, and make for aesthetic sunsets, plumes can also affect tropical development during hurricane season.Plumes consist of drier air, which works against tropical cyclone formationWe’ll see a haze in the sky, but major issues to air quality are *not* expectedThe sky will likely look a bit hazy at times this week as.
Plumes of Saharan dust filtering off the coast of Africa have helped to suppress some of that development, due to the drier layer of air it adds to the atmosphere. We didn’t see a whole lot of dust filter across the Atlantic in June, but bigger concentrations of dust finally started to emerge in July.
NHC forecasters have given this tropical wave a low of tropical development over the next seven days as it moves northwest over the warm ocean waters just north of the Lesser Antilles.

Digital Skills Provide a Development Path for Sub-Saharan AfricaSub-Saharan Africa is urbanizing with massive rural-urban migration. But unlike the urbanization of the Western world, Sub-Saharan Africa is missing a critical component: industrialized urban cities. Because of this, these urban areas have become overcrowded with substandard housing and severely inadequate infrastructure to cope with unplanned population growth. Fortunately, a new development playbook to solve this problem is already evolving, and it is anchored on the young people equipped with advanced digital skills in Sub-Saharan Africa. These young workers are digitally savvy, creative, and can lead a massive transformation — if they’re equipped and supported to unlock their potential. They can export digital skills to Western Europe, United States, and Asia through the unbounded and unconstrained opportunities the internet has provided through “digital jobs” from music to software development to prompt engineering. But to scale this and make it a success, changes must be taken into consideration at both the policy level and in implementation in the areas of quality digital education, tax treaties and harmonization, and outsourcing-focused startups.
