What classification of tropical cyclone would have closed isobars, counter clockwise rotary circulation, and sustained winds between 34 and 63 knots?

Correct Answer: Option A — A tropical storm

Tropical cyclones are classified by sustained wind speeds. A tropical depression has winds below 34 knots. A tropical storm is defined by sustained winds ranging from 34 to 63 knots, characterized by closed isobars and a distinct counter-clockwise rotary circulation in the Northern Hemisphere, as defined by NWS standards.
