What is the difference between a Nor’easter and a tropical cyclone? I can’t find the answer.

Nor’easters develop in response to the sharp contrast in the warm Gulf Stream ocean current coming up from the tropical Atlantic and the cold air masses coming down from Canada. Very cold and dry air rushing southward and meeting up with the warm Gulf stream current, which is typically near 70 °F (21 °C) even mid-winter, often causes low-pressure areas to develop and intensify.
Nor’easters differ from tropical cyclones in that nor’easters are cold-core low-pressure systems, meaning that they thrive on drastic changes in temperature of Canadian air and warm Atlantic waters. Tropical cyclones are warm-core low-pressure systems, which means they thrive on purely warm temperatures. However, in rare cases, such as the 1991 Perfect Storm, a small tropical cyclone can develop inside the warm seclusion of an intense nor’easter if the sea surface temperatures are sufficiently warm. Nor’easters can rarely also turn into tropical or subtropical cyclones, such as Tropical Storm Wanda in 2021.

As far as I can tell, nor’easters don’t typically twirl. They are hurricane wanna-bees.
