Cape Verde Islands

March 4, 2011
Winter brings sunshine and dry weather to the Cape Verde Islands, a combination that withers vegetation and causes the land to appear dull tan instead of the rich verdant green of summertime. The color of winter can be clearly seen in this image acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) of February 25, 2011.

The dry season begins in December and ends with rains that begin in late July or August, and the winds are steady and strong year round. In Africa, just 570 km to the east, winter brings the Sahel winds - strong winds that blow across the Sahara and adjacent Sahel region. These winds can carry approximately one billion tons of dust from African soils annually, much of which is transported across the Atlantic Ocean. In this image, a brownish haze hangs in the air. It is almost certainly a veil of African dust.
