North african dust emissions and transport
WebSaharan dust emissions and transports are sensitive to weather and climate conditions in the source regions. Dense dust clouds reduce the ocean surface exposure to sunlight, hence, reducing the ocean surface heating and therefore influencing the air-sea transfer of water vapor and latent heat , which are critical to climate.
