Cloud videographer, Fabiano Diniz rencently sent a time lapse video he made during 4 days in his hometown, Curitiba, in southern Brazil. He told us that Curitiba is normally a very cloudy city, both in winter and summer. At night, low stratus clouds originating from the Sea Mountain Ridge (to the east of Curitiba) cover the area. Fog is not uncommon and it can be seen in the video.
The time lapse begins on December 9th at 7:23pm and ends on December 13th at 9:00pm, 2015 (daylight savings).
