Which definition best describes "directional shear?"
occurs when winds high in the atmosphere are moving faster than winds at the surface

changes in wind direction at different altitudes causing rising air to begin to rotate
the boundary between cold and warm air at the surface during a thunderstorm which forces warm air up into the storm cell

a small storm often accompanied by heavy precipitation and frequent thunder and lightning
a tropical cyclone occurring in the western Pacific or Indian oceans
Which definition best describes "supercell?"
a rising of the sea as a result of atmospheric pressure changes and wind associated with a storm
