More than 100,000 thunderstorms impact the United States each year, but did you know there are different types of storms?  Here are some that you may hear meteorologists mention and the dangers of each one.

The Weather Channel describes three main types of thunderstorms: single-cell (pulse), squall line, and supercell storms. Single-cell thunderstorms are common, short-lived, and typically limited in strength due to their structure.

Squall lines form when two air masses collide, often along a cold front, and can produce tornadoes, hail, and damaging winds. Supercells are the most dangerous, featuring strong rotating updrafts and responsible for nearly all significant tornadoes in the United States.

Different types of thunderstorms can have different impacts

One of the most common kinds of thunderstorms is something called a pulse, or single-cell thunderstorm. These storms are usually fairly short-lived and limited in terms of strength, because the downdraft and falling rain cut off the updraft, depriving the storm of moisture. When two air masses collide, like along a cold front, you can get something called a squall line, which is an organized line of thunderstorms. Squall lines can have tornadoes, hail, and damaging straight-line winds all embedded within the line. But the most dangerous and most awe-inspiring of all storms is the supercell. These storms are massive and can be long-lived using wind shear, the difference in wind speed or direction between the surface and upper air levels, to form a deep and strong rotating updraft called a mesocyclone. These storms can also be incredibly beautiful, but only from a distance, because supercells can have very large hail, and they're responsible for nearly all of the United States' significant tornadoes.
