Fujiwhara effect. On Tuesday afternoon, as the storm approached the Bay Area, the system developed two "eyes," or areas of low pressure, resulting in a "doubled-barreled blow" to San Francisco and ...
That data shows the El Reno–Piedmont tornado and a separate cyclonic tornado, originating from the same mesocyclone, rotating in a counterclockwise fashion about a single common center (in a demonstration of the Fujiwhara effect) for several minutes, before merging at approximately 4:35 p.m. [26]: 3033 The second satellite came just minutes ...
"In the original Twister, the idea of putting these Dorothy sensor balls into a tornado is completely science fiction, but it inspired a generation of people to want to do scientific research on ...
