Hello all,
This Sunday a couple of rounds of small isolated storms with short lifecycle (1 to 2 hours) kept poping through the afternoon in my area. GFS showed CAPE at 2500j/kg, Lifted Index around -4 and EHI at -0,5, mostly instability enhanced.
This is the 12Z sounding from São Paulo, about 140 miles to the east-southeast.

The storms were low topped and the radar images showed max reflectivity around 50/55dbz.
One of the storms had a nice wall cloud and it got pretty clear that it had rotation.

Thank you
 
Great southern hemisphere storm. Mirror image of a supercell environment hodograph that we would see here in the northern hemisphere and CLOCKWISE low-level rotation. I'm always intrigued by footage of southern hemisphere storms because we don't see that type of rotation here, unless we get a rare split storm that rotates anticyclonically. Great catch!
 
Thank you! I have to say that since I began this hobby watching videos from up there, reading some texts like the Skywarn guides, etc, I used to get confused with the position of the storm structures haha.
