Mammatus Clouds over Nebraska
Explanation: When do cloud bottoms appear like bubbles? Normally,
cloud bottoms are flat. This is because moist warm air that rises and cools will
condense into water droplets at a specific temperature, which usually corresponds to a very specific height. As water
droplets grow, an opaque cloud forms. Under some conditions, however,
cloud pockets can develop that contain large droplets of water or
ice that fall into clear air as they evaporate. Such
pockets may occur in
turbulent air near a
thunderstorm. Resulting
mammatus clouds can appear especially
dramatic if sunlit from the side. The
mammatus clouds
pictured above were photographed over
Hastings,
Nebraska during 2004 June.

I disagree. I have a soft spot for brick brutalism in architecture. I think the whole image is superb.
