The Saharan dust which is transported over many countries in West Africa near the Gulf of Guinea (5°N) during the northern winter, known as the Harmattan period, is presented. The Harmattan dust phenomenon has influence on the climate of the region.

A back trajectory model of the Sahara dust flux toward the Gulf of Guinea has been studied. First, the atmospheric circulation over North and West Africa in winter is obtained by the backward trajectory plots with NOAA HYSPLIT to establish the winds

The particle size, number and mass concentrations of Saharan dust during three successive Harmattan seasons in 1996, 1997 and 1998 in southern Ghana (6°40′N, 1°34′W) are reported. The transport distance for the dust was approximately 3000 km fr

Laser holographic techniques are used to observe and measure the liquid droplets (film drops) produced by air bubbles bursting in both seawater and distilled water. Film drop aerosol production is found not only to be a function of parent bubble size

It has been estimated that 240 ± 80 Tg of Saharan dust are transported annually from Africa over the Atlantic Ocean to far away places such as the Amazon Basin and the Caribbean during the summer months of June to August. There are, however, few dir

The marine droplet aerosol, composed of the film and jet drops produced by breaking bubbles, is at the origin of most of the sea salt particles found in the atmosphere. For a long time, it was believed that the number of film drops produced per bubbl

The liquid droplets produced from the breaking up of the film cap of oceanic bubbles have long been considered as constituting a significant fraction of the marine aerosol. The size and number distributions of these film drops are investigated for si
