#WxGeekSpeak: The Triple Point

Every week, the blog introduces you to a technical term from the American Meteorology Society’s “Glossary of Meteorology”. Welcome to #WxGeekSpeak!

When forecasting the origin of thunderstorm development in the Plains, this is an important feature to look for on weather maps. Click the video above to learn the science of the triple point.

Full definition of triple point:

The intersection point between two boundaries (dry line, outflow boundary, cold front, etc.), often a focus for thunderstorm development. Triple point also may refer to a point on the gust front of a supercell, where the warm moist inflow, the rain-cooled outflow from the forward flank downdraft, and the rear flank downdraft all intersect; this point is a favored location for tornado development (or redevelopment).
