    Strong winds were blowing streamers of dust from the Bodele Depression
    almost every day in November 2022. The Moderate Resolution Imaging
    Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a
    true-color image of Chad on November 25 when thick bands of
    light-colored dust were rising from the Depression and blowing towards
    the southwest.

    Winds frequently from northeast to southwest across parts of northern
    Africa, especially during the Northern Hemisphere autumn and winter. In
    Chad, such winds are concentrated as they blow through a gap between
    two mountain ranges in the northern section of the country. This wind
    then crosses the Bodele Depression, the site of a massive dried-up
    ancient lake in Chad, where they pick up light-colored dust from the
    bed of the nearly-extinct lake. In the lower right section of the image
    (southeast) a bit of green marks the northern edge of Lake Chad, the
    modern small remnant of the ancient lake.
