Sahara Desert spread over Niger and Nigeria observed by " SHIKISAI ".
It can be seen that the clouds that occurred in the tropical rainforest climate zone at the bottom of the image (Nigeria) could not reach the desert area at the top of the image (Niger).
The area at the top of the image is called the Sahel area in the Sahara Desert.
The Sahel used to be a lush green area, but due to the effects of recent climate change and other factors, desertification is progressing.
