What is a role of Saharan dust on hurricanes? 🌪🌧 Hurricanes, including tropical cyclone rainfall (TCR), are among the most destructive weather phenomena on Earth. 🌡💧Traditionally, sea surface temperature or humidity in the atmosphere were considered as the main factor controlling hurricane precipitation. 🏜❗️Now, scientists believe that Sahara dust plays a leading role on hurricane formation over the ocean, which affects weather in America. ℹ️ Previous studies have found that Saharan dust transport may decline in the future and TCR could increase due to a climate change. ➡️⬅️According to a recent research, dust can however have competing effects on TCR. ✔️A dust particle can make ice clouds form more efficiently in the core of the hurricane, which can produce more precipitation. ✔️Dust can also block solar radiation and cool sea surface temperatures around a storm’s core, which weakens the TCR. At high concentrations, dust shifts from boosting to suppressing rainfall. Subscribe- t.me/askmenow
