Cumulonimbus Over Buenos Aires, Argentina
March 09, 2016
Photographer: Omar Curcio
The photo above shows a towering cumulonimbus cloud observed near Buenos Aires, Argentina, on February 16, 2016 -- a hot, humid summer's day. The camera is facing east. Rainfall during the summer season in northeastern Argentina is often the result of convective storms that develop during the late afternoon hours. Fueled by strong updrafts, this impressive storm was still building when the picture was snapped.
