Mexico – January 29th, 2013
The spotty clouds over the Yucatán Peninsula are likely an indication of rapid plant growth after a dry spell. During periods in which little rain falls, plants receive more sunlight, leading to an increase in growth and photosynthesis. The latter, in turn, releases water vapor into the air which then rises and cools, causing it to condense into the small, dotted clouds like those visible here. The clouds are often referred to as “popcorn” clouds due to this dotted appearance. Also of note in the image are sediments framing the coastline, particularly by Términos Lagoon (below).
